Abstract
BACKGROUND Literature demonstrated that procedure volumes affect outcomes of patients undergoing transcatheter aortic valve implantation. We evaluated the outcomes of surgical aortic valve replacement. METHODS All isolated surgical aortic valve replacement procedures in Germany in 2017 were identified. Hospitals were divided into five groups from ≤25 (very low volume) until >100 (very high volume) annual procedures. RESULTS In 2017, 5,533 patients underwent isolated surgical aortic valve replacement. All groups were of comparable risk (logistic EuroSCORE, 5.12-4.80%) and age (66.6-68.1 years). In-hospital mortality and complication rates were lowest in the very high-volume group. Multivariable logistic regression analyses showed no significant volume-outcome relationship for in-hospital mortality, stroke, postoperative delirium, and mechanical ventilation > 48 hours. Regarding acute kidney injury, patients in the very high-volume group were at lower risk than those in the very low volume group (odds ratio [OR] = 0.53, p = 0.04). Risk factors for in-hospital mortality were previous cardiac surgery (OR = 5.75, p < 0.001), high-grade renal disease (glomerular filtration rate < 15 mL/min, OR = 5.61, p = 0.002), surgery in emergency cases (OR = 2.71, p = 0.002), and higher grade heart failure (NYHA [New York Heart Association] III/IV; OR = 1.80, p = 0.02). Risk factors for all four complication rates were atrial fibrillation and diabetes mellitus. CONCLUSION Patients treated in very low volume centers (≤25 operations/year) had a similar risk regarding in-hospital mortality and most complications compared with very high-volume centers (>100 operations/year). Only in the case of acute kidney injury, very high-volume centers showed better outcomes than very low volume centers. Therefore, surgical aortic valve replacement can be performed safely independent of case volume.

Abstract
BACKGROUND In transcatheter aortic valve replacement (TAVR), complications may force the need for a surgical bailout, but knowledge is rare about outcomes in Germany. METHODS Using national health records, we investigated all TAVR in German hospitals between 2007 and 2020, focusing on 2018-2020. We extracted data on those interventions with need for a surgical bailout. RESULTS A total of 159,643 TAVR were analyzed, with an overall rate of surgical bailout of 2.30 %, an overall in-hospital mortality of 3.85 %, and in-hospital mortality in case of bailout of 16.51 %. The number of all annual TAVR procedures increased substantially (202 to 22,972), with the rate of surgical bailout declining from 27.23 to 0.61 % and overall mortality from 11.39 to 2.29 %. However, in-hospital mortality after bailout was still high (28.37 % in 2020). The standardized rates of overall mortality and surgical bailout between 2018 and 2020 were significantly lower for balloon-expandable and self-expanding transfemoral TAVR than for transapical TAVR after risk adjustment [transapical/transfemoral balloon-expandable/transfemoral self-expanding TAVR: in-hospital mortality: 5.66 % (95 % CI 4.81 %; 6.52 %)/2.30 % (2.03 %; 2.57 %)/2.32 % (2.07 %; 2.57 %); surgical bailout: 2.33 % (1.68 %; 2.97 %)/0.79 % (0.60 %; 0.98 %)/0.42 % (0.31 %; 0.53 %)]. Coronary artery disease [risk-adjusted OR = 1.50 (1.21; 1.85), p < 0.001] and atrial fibrillation [OR = 1.29 (1.07; 1.57), p = 0.009] were found to be the main risk factors for bailout. CONCLUSIONS Rates of TAVR with need for a surgical bailout and overall in-hospital mortality have declined noticeably over the years in Germany. However, the outcomes are still unfavorable after surgical bailout, as in-hospital mortality is continuously high. We present risk factors for surgical bailout to improve preparation of subsequent measures. It must be a major goal to further reduce the rate of surgical bailouts in the future.

Abstract
BACKGROUND Previously, overall comparable outcomes were seen for balloon-expandable (BE) or self-expanding (SE) transfemoral transcatheter aortic valve replacement (TAVR). However, subgroup analyses based on large case numbers are still needed. METHODS German national data of all BE and SE transfemoral TAVR treating aortic valve stenosis in 2019 and 2020 were analysed. We then compared different outcomes and performed a subgroup analysis for the endpoint in-hospital mortality. RESULTS Overall, 46,243 TAVR were analysed, 19,910 BE, and 26,333 SE. Patients in the SE group had a significantly higher logistic EuroSCORE (13.61 vs 12.66%, p < 0.001), age (81.55 vs 79.99a, p < 0.001), and proportion of women (54.82 vs 40.06%, p < 0.001). Both groups showed a similar in-hospital mortality with 2.37% in BE and 2.35% in SE (p = 0.916). In-hospital mortality also did not differ significantly after risk adjustment (OR = 0.98 [0.86, 1.13], p = 0.799). Patients in the SE group had a significantly lower risk of major bleeding (OR = 0.83 [0.73, 0.95], p = 0.006), but a significantly higher risk of stroke (OR = 1.38 [1.19, 1.59], p < 0.001), delirium (OR = 1.15 [1.06, 1.24], p = 0.001), and permanent pacemaker implantation (OR = 1.29 [1.21, 1.37], p < 0.001). In the subgroup analysis of in-hospital mortality, there were no significant differences in any of the observed subgroups (age < 75/75-79/80-84/ ≥ 85a, logistic EuroSCORE < 4/4- < 9/ ≥ 9, gender, NYHA III/IV, previous CABG, peripheral vascular disease, COPD, pulmonary hypertension, renal disease GFR < 30 ml/min, and diabetes mellitus). CONCLUSION In the direct comparison of balloon-expandable and self-expanding TAVR, there are no differences for in-hospital mortality in subgroups.

Abstract
Aims Literature on percutaneous coronary intervention (PCI) stated an inverse relationship between hospital volume and mortality, but the effects on other characteristics are unclear. Methods Using German national records, all coronary angiographies with coronary artery disease in 2017 were identified. We applied risk-adjustment to account for differences in population characteristics. Results Of overall 528,188 patients, 55.22% received at least one stent, with on average 1.01 stents implanted in all patients. Based on those patients who received at least one stent, this corresponds to an average number of 1.82 stents. In-hospital mortality across all patients was 2.93%, length of hospital stay was 6.46 days, and mean reimbursement was €5,531. There were comparatively more emergency admissions in low volume centers and more complex cases (3-vessel disease, left main stenosis, and in-stent stenosis) in high volume centers. In multivariable regression analysis, volume and likelihood of stent implantation (p=0.003) as well as number of stents (p=0.020) were positively correlated. No relationship was seen for in-hospital mortality (p=0.105), length of stay (p=0.201), and reimbursement (p=0.108). Nonlinear influence of volume suggests a ceiling effect: In hospitals with ≤100 interventions, likelihood and number of implanted stents are lowest (∼34% and 0.6). After that, both rise steadily until a volume of 500 interventions. Finally, both remain stable in the categories of over 500 interventions (∼60% and 1.1). Conclusion In PCI, lower volume centers contribute to emergency care. Higher volume centers treat more complex cases and show a higher likelihood of stent implantations, with a stable safety.

Abstract
AIMS Current long QT syndrome (LQTS) therapy, largely based on beta-blockade, does not prevent arrhythmias in all patients; therefore, novel therapies are warranted. Pharmacological inhibition of the serum/glucocorticoid-regulated kinase 1 (SGK1-Inh) has been shown to shorten action potential duration (APD) in LQTS type 3. We aimed to investigate whether SGK1-Inh could similarly shorten APD in LQTS types 1 and 2. METHODS AND RESULTS Human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) and hiPSC-cardiac cell sheets (CCS) were obtained from LQT1 and LQT2 patients; CMs were isolated from transgenic LQT1, LQT2, and wild-type (WT) rabbits. Serum/glucocorticoid-regulated kinase 1 inhibition effects (300 nM-10 µM) on field potential durations (FPD) were investigated in hiPSC-CMs with multielectrode arrays; optical mapping was performed in LQT2 CCS. Whole-cell and perforated patch clamp recordings were performed in isolated LQT1, LQT2, and WT rabbit CMs to investigate SGK1-Inh (3 µM) effects on APD. In all LQT2 models across different species (hiPSC-CMs, hiPSC-CCS, and rabbit CMs) and independent of the disease-causing variant (KCNH2-p.A561V/p.A614V/p.G628S/IVS9-28A/G), SGK1-Inh dose-dependently shortened FPD/APD at 0.3-10 µM (by 20-32%/25-30%/44-45%). Importantly, in LQT2 rabbit CMs, 3 µM SGK1-Inh normalized APD to its WT value. A significant FPD shortening was observed in KCNQ1-p.R594Q hiPSC-CMs at 1/3/10 µM (by 19/26/35%) and in KCNQ1-p.A341V hiPSC-CMs at 10 µM (by 29%). No SGK1-Inh-induced FPD/APD shortening effect was observed in LQT1 KCNQ1-p.A341V hiPSC-CMs or KCNQ1-p.Y315S rabbit CMs at 0.3-3 µM. CONCLUSION A robust SGK1-Inh-induced APD shortening was observed across different LQT2 models, species, and genetic variants but less consistently in LQT1 models. This suggests a genotype- and variant-specific beneficial effect of this novel therapeutic approach in LQTS.

Abstract
BACKGROUND Electromechanical reciprocity - comprising electro-mechanical (EMC) and mechano-electric coupling (MEC) - provides cardiac adaptation to changing physiological demands. Understanding electromechanical reciprocity and its impact on function and heterogeneity in pathological conditions - such as (drug-induced) acquired long QT syndrome (aLQTS) - might lead to novel insights in arrhythmogenesis. Our aim is to investigate how electrical changes impact on mechanical function (EMC) and vice versa (MEC) under physiological conditions and in aLQTS. METHODS To measure regional differences in EMC and MEC in vivo, we used tissue phase mapping cardiac MRI and 24-lead ECG vest in healthy (control) and IKr -blocker E-4031-induced aLQTS rabbit hearts. MEC was studied in vivo by acutely increasing cardiac preload, and ex vivo by using voltage optical mapping in beating hearts at different preloads. RESULTS In aLQTS, electrical repolarization (heart rate corrected RT-interval, RTn370) was prolonged compared to control (p<0.0001) with increased spatial and temporal RT heterogeneity (p<0.01). Changing electrical function (in aLQTS) resulted in significantly reduced diastolic mechanical function and prolonged contraction duration (EMC), causing increased apico-basal mechanical heterogeneity. Increased preload acutely prolonged RTn370 in both control and aLQTS hearts (MEC). This effect was more pronounced in aLQTS (p<0.0001). Additionally, regional RT-dispersion increased in aLQTS. Motion-correction allowed to determine APD-prolongation in beating aLQTS hearts, but limited motion correction accuracy upon preload-changes prevented a clear analysis of MEC ex vivo. CONCLUSION Mechano-induced RT-prolongation and increased heterogeneity were more pronounced in aLQTS than in healthy hearts. Acute MEC effects may play an additional role in LQT-related arrhythmogenesis, warranting further mechanistic investigations. KEY POINT SUMMARY Electromechanical reciprocity - comprising excitation-contraction coupling (EMC) and mechano-electric feedback loops (MEC) - is essential for physiological cardiac function. Alterations in electrical and/or mechanical heterogeneity are known to have potentially pro-arrhythmic effects. In this study, we aimed to investigate how electrical changes impact on the mechanical function (EMC) and vice versa (MEC) - both under physiological conditions (control) and in acquired long QT syndrome (aLQTS). We show that changing the electrical function (in aLQTS) results in significantly altered mechanical heterogeneity via EMC and - vice versa - that increasing the preload acutely prolongs repolarization duration and increases electrical heterogeneity, particularly in aLQTS as compared to control. Our results substantiate the hypothesis that LQTS is an 'electro-mechanical' - rather than a 'purely electrical' - disease and suggest that acute MEC effects may play an additional role in LQT-related arrhythmogenesis.

Abstract
BACKGROUND COVID-19 has caused the deferral of millions of elective procedures, likely resulting in a backlog of cases. We estimate the number of postponed surgical aortic valve replacement (sAVR) and transcatheter aortic valve replacement (TAVR) procedures during the first two waves of the COVID-19 pandemic in Germany. METHODS Using German national records, all isolated TAVR and sAVR procedures between 2007 and 2020 were identified. Using weekly TAVR and sAVR procedures between 2017 and 2019, we created a forecast for 2020 and compared it with the observed number of procedures in 2020. RESULTS In Germany, a total of 225,398 isolated sAVR and 159,638 isolated TAVR procedures were conducted between 2007 and 2020 that were included in our analysis. The reduction in all AVR procedures (sAVR and TAVR) for the entire year 2020 was 19.07% (95%CI: 15.19-22.95%). During the first wave of the pandemic (week 12-21), the mean weekly reduction was 32.06% (23.44-40.68%) and during the second wave of the pandemic (week 41-52), the mean weekly reduction was 25.58% (14.19-36.97%). The number of sAVR procedures decreased more than the number of TAVR procedures (24.63% vs. 16.42% for the entire year 2020). CONCLUSION The first year of the COVID-19 pandemic saw a substantial postponing of AVR procedures in Germany. Postponing was higher for sAVR than for TAVR procedures and less pronounced during the second wave of the COVID-19 pandemic.

Abstract
Background In pure aortic regurgitation, transcatheter aortic valve replacement (TAVR) is not yet used on a regular base. Due to constant development of TAVR, it is necessary to analyze current data. Methods By use of health records, we analyzed all isolated TAVR or surgical aortic valve replacements (SAVR) for pure aortic regurgitation between 2018 and 2020 in Germany. Results 4,861 procedures-4,025 SAVR and 836 TAVR-for aortic regurgitation were identified. Patients treated with TAVR were older, showed a higher logistic EuroSCORE, and had more pre-existing diseases. While results indicate a slightly higher unadjusted in-hospital mortality for transapical TAVR (6.00%) vs. SAVR (5.71%), transfemoral TAVR showed better outcomes, with self-expanding compared to balloon-expandable transfemoral TAVR having significantly lower in-hospital mortality (2.41% vs. 5.17%; p = 0.039). After risk adjustment, balloon-expandable as well as self-expanding transfemoral TAVR were associated with a significantly lower mortality vs. SAVR (balloon-expandable: risk adjusted OR = 0.50 [95% CI 0.27; 0.94], p = 0.031; self-expanding: OR = 0.20 [0.10; 0.41], p < 0.001). Furthermore, the observed in-hospital outcomes of stroke, major bleeding, delirium, and mechanical ventilation >48 h were significantly in favor of TAVR. In addition, TAVR showed a significantly shorter length of hospital stay compared to SAVR (transapical: risk adjusted Coefficient = -4.75d [-7.05d; -2.46d], p < 0.001; balloon-expandable: Coefficient = -6.88d [-9.06d; -4.69d], p < 0.001; self-expanding: Coefficient = -7.22 [-8.95; -5.49], p < 0.001). Conclusions TAVR is a viable alternative to SAVR in the treatment of pure aortic regurgitation for selected patients, showing overall low in-hospital mortality and complication rates, especially with regard to self-expanding transfemoral TAVR.

Abstract
Background The COVID-19 pandemic led to extensive restrictions in Germany in 2020, including the postponement of elective interventions. We examined the impact on ST-elevation myocardial infarction (STEMI) as an acute and non-postponable disease. Methods Using German national records, all STEMI between 2017 and 2020 were identified. Using the number of STEMI cases between 2017 and 2019, we created a forecast for 2020 and compared it with the observed number of STEMI in 2020. Results From 2017 to 2020, 248,062 patients were treated for STEMI in Germany. Mean age was 65.21 years and 28.36% were female. When comparing forecasted and observed STEMI in 2020, a correlation can be seen: noticeable fewer STEMI were treated in those weeks respectively months with an increasing COVID-19 hospitalization rate (monthly percentage decrease in STEMI: March − 14.85%, April − 13.39%, November − 11.92%, December − 22.95%). At the same time, the crude in-hospital mortality after STEMI increased significantly at the peaks of the first and second waves (relative risk/RR of monthly in-hospital mortality: April RR = 1.11 [95% CI 1.02; 1.21], November RR = 1.13 [1.04; 1.24], December RR = 1.16 [1.06; 1.27]). Conclusion The COVID-19 pandemic led to a noticeable decrease in the number of STEMI interventions in Germany at the peaks of the first and second waves in 2020, corresponding to an increase in COVID-19 hospitalizations. At the same time, in-hospital mortality after STEMI increased significantly in these phases. Graphical abstract Impact of the COVID-19 pandemic on STEMI numbers and in-hospital mortality in Germany.

Abstract
Abstract
Background
Severe complications during transcatheter aortic valve replacement (TAVR) may require a surgical bailout. However, little is known about the outcomes after bailout in Germany.
Methods
All TAVR between 2007 and 2020 were identified using German national electronic health records, with focus on 2018 to 2020. Additionally, those procedures requiring surgical bailout were selected.
Results
A total of 159,643 patients received TAVR. Overall rate of surgical bailout was 2.30% and overall in-hospital mortality 3.85%. In-hospital mortality after surgical bailout was 16.51%. While the annual number of procedures in all TAVR rose steeply (202 to 22,972), the rate of surgical bailout dropped from 27.23 to 0.61% and that of overall mortality from 11.39 to 2.29%. However, mortality in case of surgical bailout remained high with 28.37% in 2020. After risk adjustment, in 2018 to 2020, standardized rates of overall in-hospital mortality and surgical bailout for both balloon-expandable and self-expanding transfemoral TAVR were significantly lower than for transapical TAVR (transapical vs transfemoral balloon-expandable vs self-expanding TAVR: in-hospital mortality: 5.66% [95% CI 4.81%; 6.52%] vs 2.30% [2.03%; 2.57%] vs 2.32% [2.07%; 2.57%]; surgical bailout: 2.33% [1.68%; 2.97%] vs 0.79% [0.60%; 0.98%] vs 0.42% [0.31%; 0.53%]). Main risk factors for surgical bailout were coronary artery disease (risk adjusted OR=1.50 [1.21; 1.85], p<0.001), atrial fibrillation (OR=1.29 [1.07; 1.57], p=0.009), and higher grade heart failure NYHA III/IV (OR=1.26 [1.01; 1.57], p=0.037).
Conclusion
Rates of surgical bailout as well as overall in-hospital mortality after TAVR decrease substantially over the years. However, in the case of surgical bailout, outcomes remain poor with a constantly high in-hospital mortality.

Abstract
Abstract
Background
An inverse volume-outcome relationship in transcatheter aortic valve implantation (TAVI) has been demonstrated in the literature but little is known about emergency cases.
Methods
All isolated balloon-expandable and self-expanding transfemoral TAVI in 2018 were identified using German national electronic health records. Additionally, those patients with an emergency admission were selected.
Results
A total of 17,295 patients received TAVI, 1,682 of these cases had an emergency admission. Of the emergency cases, 49.2% were female, mean age was 81.2 years and logistic EuroSCORE was 23.3%. Relatively more emergency cases were treated in lower volume centers than in higher volume centers (p<0.001): Centers performing <50 TAVI had an emergency admission rate of ∼15% while centers performing >200 TAVI were associated with a rate of ∼11%. Analyzing the outcomes for a volume increase per 10 emergency cases using propensity score adjustment, higher volume centers showed significantly better results than lower volume centers for in-hospital mortality (OR=0.872, p=0.043), major bleeding (OR=0.772, p=0.001), stroke (OR=0.816, p=0.044), mechanical ventilation >48h (OR=0.749, p=0.001), length of hospital stay (risk adjusted difference in days of hospitalization per 10 emergency admissions: −1.01 days, p<0.001), and reimbursement (risk adjusted difference in reimbursement per 10 emergency admissions: −€314.89, p<0.001). No correlation was seen in acute kidney injury (OR=0.951, p=0.104), postoperative delirium (OR=0.975, p=0.480), and permanent pacemaker implantation (OR=1.010, p=0.732).
Conclusion
In transfemoral TAVI, lower volume centers treat relatively more emergency cases in Germany, but higher volume centers provide significantly better outcomes regarding in-hospital mortality and complication rates as well as resource utilization parameters.

At the same time, the risk-adjusted in-hospital mortality increased significantly at the peaks of the first and second waves (monthly in-hospital mortality: April RR=1.11 [95% CI 1.02; 1.21], November 1.13 [1.04; 1.24], December 1.16 [1.06; 1.27]). Conclusion The COVID-19 pandemic led to a noticeable decrease in the number of STEMI interventions in Germany at the peaks of the first and second waves in 2020, corresponding to an increase in COVID-19 hospitalizations. At the same time, in-hospital mortality after STEMI increased significantly in these phases. Funding Acknowledgement Type of funding sources: None.

Abstract
BACKGROUND The hospital mortality of patients suffering from pulmonary failure requiring venovenous extracorporeal membrane oxygenation (V-V ECMO) or extracorporeal carbon dioxide removal (ECCO2 R) is high. It is unclear whether outcome correlates with a hospital's annual procedural volume. METHODS Data on all V-V ECMO and ECCO2 R cases treated from 2007 to 2019 was retrieved from the German Institute for Medical Documentation and Information. Comorbidities and outcomes were assessed by DRG, OPS, and ICD codes. The study population was divided into 5 groups depending on annual hospital V-V ECMO and ECCO2 R volumes (<10 cases; 10-19 cases; 20-29 cases; 30-49 cases; ≥50 cases). Primary outcome was hospital mortality. RESULTS A total of 25,096 V-V ECMO and 3,607 ECCO2 R cases were analyzed. V-V ECMO hospitals increased from 89 in 2007 to 214 in 2019. Hospitals handling <10 cases annually increased especially (64 in 2007 to 149 in 2019). V-V ECMO cases rose from 807 in 2007 to 2,597 in 2019. Over 50% were treated in hospitals handling ≥30 cases annually. Hospital mortality was independent of the annual hospital procedural volume (55.3%; 61.3%; 59.8%; 60.2%; 56.3%, respectively, p=0.287). We detected no differences when comparing hospitals handling <30 cases to those with ≥30 annually (p=0.659). The numbers of ECCO2 R hospitals and cases has dropped since 2011 (287 in 2007 to 48 in 2019). No correlation between annual hospital procedural volume and hospital mortality was identified (p=0.914). CONCLUSION The number of hospitals treating patients requiring V-V ECMO and V-V ECMO cases rose from 2007 to 2019, while ECCO2 R hospitals and their case numbers decreased. We detected no correlation between annual hospital V-V ECMO or ECCO2 R volume and hospital mortality.

Abstract
Background Oxytocin is used therapeutically in psychiatric patients. Many of these also receive anti-depressant or anti-psychotic drugs causing acquired long-QT-syndrome (LQTS) by blocking HERG/IKr. We previously identified an oxytocin-induced QT-prolongation in LQT2 rabbits, indicating potential harmful effects of combined therapy. We thus aimed to analyze the effects of dual therapy with oxytocin and fluoxetine/risperidone on cardiac repolarization. Methods Effects of risperidone, fluoxetine and oxytocin on QT/QTc, short-term variability (STV) of QT, and APD were assessed in rabbits using in vivo ECG and ex vivo monophasic AP recordings in Langendorff-perfused hearts. Underlying mechanisms were assessed using patch clamp in isolated cardiomyocytes. Results Oxytocin, fluoxetine and risperidone prolonged QTc and APD in whole hearts. The combination of fluoxetine + oxytocin resulted in further QTc- and APD-prolongation, risperidone + oxytocin tended to increase QTc and APD compared to monotherapy. Temporal QT instability, STVQTc was increased by oxytocin, fluoxetine / fluoxetine + oxytocin and risperidone / risperidone + oxytocin. Similar APD-prolonging effects were confirmed in isolated cardiomyocytes due to differential effects of the compounds on repolarizing ion currents: Oxytocin reduced IKs, fluoxetine and risperidone reduced IKr, resulting in additive effects on IKtotal-tail. In addition, oxytocin reduced IK1, further reducing the repolarization reserve. Conclusion Oxytocin, risperidone and fluoxetine prolong QTc / APD. Combined treatment further prolongs QTc/APD due to differential effects on IKs and IK1 (block by oxytocin) and IKr (block by risperidone and fluoxetine), leading to pronounced impairment of repolarization reserve. Oxytocin should be used with caution in patients in the context of acquired LQTS.

Abstract
INTRODUCTION In patients suffering a sudden out-of-hospital cardiac arrest (OHCA), the prevalence of a coronary artery lesion as the underlying cause is relatively high, but many other causes have been described. For this reason, identifying patients who would benefit from an emergency coronary angiography is important. AREAS COVERED In the present manuscript, we reviewed the literature covering some relevant studies regarding the role of coronary angiography in patients with OHCA, including our local algorithm for the management of patients with OHCA. We particularly focused on the selection of patients who would benefit from an emergency coronary angiography, the time period until the performance of the angiography, the role of extracorporeal cardiopulmonary resuscitation (ECPR), the identification of a coronary artery lesion as the underlying cause of cardiac arrest and clinical outcomes. EXPERT OPINION In summary, a local standard algorithm for the management of patients with OHCA appears favorable. An emergency coronary angiography should be advised in patients with a presumed cardiac cause and without obvious non-cardiac cause. A shockable initial rhythm, ST elevation in the post-resuscitation ECG, a previously known coronary artery disease, and ECPR are important predictors of cardiac cause of OHCA.

Abstract
OBJECTIVES To evaluate in-hospital outcomes of concomitant mitral valve replacement (MVR) in patients undergoing conventional aortic valve replacement due to aortic stenosis in a nationwide cohort. METHODS Administrative data from all patients with aortic stenosis undergoing conventional aortic and concomitant MVR (reason for MVR not specified) between 2017 and 2018 in Germany were analysed. RESULTS A total of 2597 patients with a preoperative logistic EuroScore of 9.81 (standard deviation: 8.56) were identified. In-hospital mortality was 6.8%. An in-hospital stroke occurred in 3.4%, acute kidney injury in 16.3%, prolonged mechanical ventilation of more than 48 h in 16.3%, postoperative delirium in 15.8% and postoperative pacemaker implantation in 7.6% of the patients. Mean hospital stay was 16.5 (standard deviation: 12.1) days. Age [odds ratio (OR): 1.03; P = 0.019], New York Heart Association class III or IV (OR: 1.63; P = 0.012), previous cardiac surgery (OR: 2.85, P = 0.002), peripheral vascular disease (OR: 2.01, P = 0.031), pulmonary hypertension (OR: 1.63, P = 0.042) and impaired renal function (glomerular filtration rate <15, OR: 3.58, P = 0.001; glomerular filtration rate <30, OR: 2.51, P = 0.037) were identified as independent predictors for in-hospital mortality. CONCLUSIONS In this nationwide analysis, concomitant aortic and MVR was associated with acceptable in-hospital mortality, morbidity and length of in-hospital stay. The regression analyses may help to identify high-risk patients and further optimize treatment strategies.

Abstract
OBJECTIVES We aimed to identify risk factors for major transcatheter aortic valve intervention (TAVI) access site complications based on detailed analysis of the preprocedural computed tomography angiogram (CTA). BACKGROUND Transfemoral TAVI has become the treatment of choice for severe aortic stenosis in elderly patients, especially with increased perioperative risk. Frailty, however, favors complications at the vascular access site due to the large bore vascular sheath devices necessary for valve deployment. METHODS In this monocentric study, we retrospectively analyzed the preprocedural CTA of 417 consecutive patients that received transfemoral TAVI between 2015 and 2019 to quantify vessel diameter, calcification volume and calcified plaque location in detail within 10 cm proximal to the femoral bifurcation. RESULTS The mean age of the study cohort was 81.4 ± 6.5 years with a STS of 8 ± 5.2 representing a population at increased periprocedural risk. 54.4% of patients were female. Major vascular access site complications occurred in 8.2% of patients. Major vascular complications correlated statistically with a sheath-to-vessel diameter (SFAR) when measured 1 cm proximal to the femoral bifurcation using a line-derived diameter and ventral calcification within the first 5 cm proximal to the bifurcation. In contrast, overall calcification volume had no influence. CONCLUSIONS Transfemoral TAVI harbors a considerable risk for vascular access site complications especially if vessel diameter is too small to comfortably host the sheath diameter at the area of the femoral bifurcation. For preprocedural TAVI planning and risk assessment, location of calcification, especially if located ventrally, seems to be more relevant than consideration of overall calcification alone.

Abstract
Abstract
Background
The impact of valve type used in transfemoral transcatheter aortic valve replacement (TF-TAVR) on outcomes is currently under discussion.
Purpose
We examine the in-hospital outcomes of balloon-expandable (BE) and self-expanding (SE) valves in a complete national cohort in Germany in 2018.
Methods
All 17,295 patients receiving TF-TAVR with BE (N=9,882) or SE (N=7,413) valves in Germany in 2018 were identified. Outcomes were analyzed for the endpoints in-hospital mortality, major bleeding, stroke, acute kidney injury, postoperative delirium, mechanical ventilation >48h, length of hospital stay, and reimbursement. Since there was no randomization of patients to the two treatment options, logistic or linear regression models were carried out using 22 baseline patient characteristics and center-specific variables as potential confounders. Propensity score methods served as sensitivity analysis.
Results
Both valve types differed significantly in baseline characteristics with higher EuroSCORE (p<0.001), age (p<0.001) and rate of female sex (p<0.001) in patients treated with SE valves. After risk adjustment, there were no marked differences in outcomes for in-hospital mortality (risk adjusted odds ratio (aOR) for SE instead of BE: 0.94 [95% CI 0.76; 1.17], p=0.617), major bleeding (aOR 0.91 [0.73; 1.14], p=0.400), stroke (aOR 1.13 [0.88; 1.46], p=0.347), acute kidney injury (aOR 0.97 [0.85; 1.10], p=0.621), postoperative delirium (aOR 1.09 [0.96; 1.24], p=0.184), mechanical ventilation >48h (aOR 0.98 [0.77; 1.25], p=0.893), length of hospital stay (risk adjusted difference in days of hospitalization: −0.05 [−0.34; 0.25], p=0.762) and reimbursement (−€72 [−€291; €147], p=0.519). Similar results were found using propensity score methods.
Conclusion
Outcomes in contemporary TF-TAVR procedures are broadly equivalent regardless of the valve type used. Major complications rarely occur in both types of valve.

Abstract
Abstract
Background
Electro-mechanical (EMC) and mechano-electrical coupling (MEC) are essential for normal cardiac function. Alterations in these can result in increased arrhythmia formation. In “electrical” cardiac diseases, long-QT and short-QT syndrome, regional mechanical function is altered via EMC.
Purpose
In this study, we aimed to investigate how acute changes in mechanics may impact on electrical function (MEC) in these diseases.
Methods
To determine how acute changes in preload impact on QT duration, adult rabbits of both sexes were given a 6ml/kg BW bolus of 0.9% NaCl IV and 12-lead-ECGs were assessed first in wildtype (WT) and acquired drug-induced (E4031 to block IKr) LQT2 (“aLQT2”) rabbits, and in a second step in transgenic short-QT type 1 (“SQT1”, KCNH2-N588K) and WT littermate control rabbits (“WT-LMC”).
Results
At baseline, aLQT2 rabbits demonstrated a markedly prolonged heart-rate corrected QTc duration compared to WT (p<0.0001; n=13), with increased QT-dispersion (QTMax-Min [ms], WT 21.4±5.7 vs. aLQT2 25.8±5.8; p=0.003; n=13) and increased short-term variability of QT (STVQT [ms], WT 3.5±1.0 vs. aLQT2 5.3±1.7; p=0.02; n=13), markers for regional and temporal heterogeneity of repolarization, respectively. SQT1 rabbits (n=8) demonstrated a shorter QTc duration compared to WT-LMC (n=10; p=0.04), with no differences in QT-dispersion and STVQT between the two groups.
Increased preload acutely prolonged QT and heart-rate corrected QTc in all groups (despite a slight increase in heart-rate by an average of 25 beats/min): in WT [ms] 171.6±11.6 to 213.3±20.3 (p<0.0001) vs. aLQT2 208.9±19.6 to 271.0±37.5 (p<0.0001; n=13 each), and in WT-LMC 171.3±4.8 to 199.2±5.4 (p<0.0001; n=10) vs. SQT1 156.0±4.7 to 177.3±3.5 (p=0.0004; n=8). Importantly, the extent of mechano-induced electrical changes differed among genotypes, with less pronounced QTc prolongation in SQT1 compared to WT-LMC (delta QTc [ms], SQT1 21.2±3.4 (n=8) vs. WT-LMC 27.9±2.8 (n=10; p=0.15)), and a more pronounced QTc prolongation in aLQT2 compared to WT (delta QTc [ms], WT 41.6±14.9 vs. aLQT2 62.1±32.1; p=0.006; n=13 each). Moreover, QT-dispersion was increased significantly upon global mechanical change only in aLQTS (QTMax-Min [ms], 25.8±5.5 to 32.7±12.3; p=0.03; n=13).
Conclusion
Acute changes in mechanical function result in electrical changes via MEC in SQT1, WT and aLQT2 rabbits. The extent of these changes, however, depends on the underlying QTc duration, with the least pronounced QTc prolongation in SQT1 rabbits, with the shortest QTc, and the most pronounced QTc prolongation in aLQT2 rabbits, with the longest QTc. The most pronounced MEC effects on global QT duration as well as on regional QT dispersion in aLQT2 indicate that acute MEC effects may play an additional role in LQTS-related arrhythmogenesis.

Abstract
AIM Long QT syndrome (LQTS) is a cardiac channelopathy predisposing to ventricular arrhythmias and sudden cardiac death. Since current therapies often fail to prevent arrhythmic events in certain LQTS subtypes, new therapeutic strategies are needed. Docosahexaenoic acid (DHA) is a polyunsaturated fatty acid, which enhances the repolarizing IKs current. METHODS AND RESULTS We investigated the effects of DHA in wild type (WT) and transgenic long QT Type 1 (LQT1; loss of IKs), LQT2 (loss of IKr), LQT5 (reduction of IKs), and LQT2-5 (loss of IKr and reduction of IKs) rabbits. In vivo ECGs were recorded at baseline and after 10 µM/kg DHA to assess changes in heart-rate corrected QT (QTc) and short-term variability of QT (STVQT). Ex vivo monophasic action potentials were recorded in Langendorff-perfused rabbit hearts, and action potential duration (APD75) and triangulation were assessed. Docosahexaenoic acid significantly shortened QTc in vivo only in WT and LQT2 rabbits, in which both α- and β-subunits of IKs-conducting channels are functionally intact. In LQT2, this led to a normalization of QTc and of its short-term variability. Docosahexaenoic acid had no effect on QTc in LQT1, LQT5, and LQT2-5. Similarly, ex vivo, DHA shortened APD75 in WT and normalized it in LQT2, and additionally decreased AP triangulation in LQT2. CONCLUSIONS Docosahexaenoic acid exerts a genotype-specific beneficial shortening/normalizing effect on QTc and APD75 and reduces pro-arrhythmia markers STVQT and AP triangulation through activation of IKs in LQT2 rabbits but has no effects if either α- or β-subunits to IKs are functionally impaired. Docosahexaenoic acid could represent a new genotype-specific therapy in LQT2.

Abstract
Presentation and mortality of coronary artery disease (CAD) substantially differs in both sexes. Most of the existing data analyzing sex differences is older than 10 years and mostly was retrieved in clinical trials, which are potentially structured with a bias against the inclusion of women, leading to a potential selection-bias. Meanwhile, with better diagnostic and therapeutic options, actual data analyzing sex differences in emergency CAD patients is rare.Data on all emergency case numbers with CAD diagnosis in Germany 2017 was retrieved from the German Institute for Medical Documentation and Information. DRG, OPS, and ICD codes were used to determine comorbidities, in-hospital course, and outcome. Competing risk regression analysis for in-hospital mortality was performed analyzing age, European System for Cardiac Operative Risk Evaluation (EuroSCORE), severity of CAD, clinical presentation type and sex.264,742 patients were included. Female patients were older and had more comorbidities. Three-vessel CAD was significantly less present in female patients (36.5% vs 47.5%; P < .001). After adjusting for age, EuroSCORE and severity of CAD, female sex was an independent predictor of lower in-hospital mortality (subdistribution hazard ratio [sHR] 0.94, 95% CI: 0.90-0.98, P = .002) in the whole cohort and in non-ST-segment elevation myocardial infarction (NSTEMI) patients (sHR 0.85, 95% CI: 0.79-0.92, P < .001), whereas in ST-segment elevation myocardial infarction (STEMI) patients, female sex was associated with a higher in-hospital mortality (sHR 1.07, 95% CI: 1.01-1.14, P = .029).In all patients admitted as emergency with CAD diagnosis and in all NSTEMI patients, female sex is protective, whereas in STEMI patients, females show a higher in-hospital mortality risk.

Abstract
Combined implantation of cardiac contractility modulation (CCM) with subcutaneous implantable cardioverter-defibrillator (S-ICD) appears a suitable option to reduce the amount of intracardiac leads and complications for patients. Here we report on a patient with ischemic cardiomyopathy carrying an S-ICD in which a CCM device was implanted. During crosstalk testing post-CCM implantation, the S-ICD misannotated QRS complexes and T waves. The problem was solved through reprogramming the CCM, while preserving S-ICD functionality and improving heart failure symptoms. In conclusion, S-ICD combined with CCM seems to be a good and safe option for patients when device interference is being ruled out.

Abstract
Aims The early repolarization syndrome (ERS) can cause ventricular fibrillation (VF) and sudden death in young, otherwise healthy individuals. There are limited data suggesting that ERS might be heritable. The aim of this study was to characterize the clinical phenotype and to identify a causal variant in an affected family using an exome-sequencing approach. Methods and results Early repolarization syndrome was diagnosed according to the recently proposed Shanghai ERS Score. After sequencing of known ERS candidate genes, whole-exome sequencing (WES) was performed. The index patient (23 years, female) showed a dynamic inferolateral early repolarization (ER) pattern and electrical storm with intractable VF. Isoproterenol enabled successful termination of electrical storm with no recurrence on hydroquinidine therapy during 33 months of follow-up. The index patient’s brother (25 years) had a persistent inferior ER pattern with malignant features and a history of syncope. Both parents were asymptomatic and showed no ER pattern. While there was no pathogenic variant in candidate genes, WES detected a novel missense variant affecting a highly conserved residue (p. H2245R) in the ANK3 gene encoding Ankyrin-G in the two siblings and the father. Conclusion We identified two siblings with a malignant ERS phenotype sharing a novel ANK3 variant. A potentially pathogenic role of the novel ANK3 variant is suggested by the direct interaction of Ankyrin-G with the cardiac sodium channel, however, more patients with ANK3 variants and ERS would be required to establish ANK3 as novel ERS susceptibility gene. Our study provides additional evidence that ERS might be a heritable condition.

Abstract
BACKGROUND Severe aortic valve stenosis inhibits renal perfusion, thereby potentially worsening renal function, in particular in elderly patients most often assigned to transcatheter aortic valve implantation (TAVI). Pre-TAVI diagnostics and the procedure itself may adversely impact renal function, however renal perfusion and function may also improve post-procedure. This study aimed to clarify the impact of TAVI planning and procedure on kidney function METHODS: In this retrospective study, kidney function of patients who underwent transfemoral TAVI at a tertiary university hospital between 2016 and 2019 was analyzed. The present study investigated kidney function at baseline, after computed tomography (CT) was performed for evaluation of TAVI, after TAVI, at discharge and at follow-up. RESULTS Among 366 patients, the prevalence of acute kidney injury (AKI) was 14.5% after TAVI. Independent predictors of AKI were arterial hypertension, baseline creatinine, AKI post CT and coronary intervention during pre-procedural diagnostics. At discharge and follow-up, 2.1% and 3.4%, respectively had sustained relevant impairment of kidney function (defined as creatinine/baseline creatinine > 1.5 or renal replacement therapy). Patients with known chronic kidney disease showed no higher rates of short- and long-term impairment, but higher rates of improvement of renal function after TAVI. CONCLUSIONS In most cases TAVI does not worsen renal function. A sustained impairment after TAVI was found in only a few cases. This was independent of reduced baseline kidney function. Transfemoral TAVI can thus be planned and performed even in patients with higher stages of chronic kidney disease.

Abstract
OBJECTIVES This study hypothesized that cerebral protection prevents strokes in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR) in clinical practice. BACKGROUND Preventing strokes is an important aim in TAVR procedures. Embolic protection devices may protect against cardiac embolism during TAVR, but their use and outcomes in clinical practice remain controversial. METHODS Isolated transfemoral TAVR procedures performed in Germany with or without cerebral protection devices were extracted from a comprehensive nationwide billing dataset. RESULTS A total of 41,654 TAVR procedures performed between 2015 and 2017 were analyzed. The overall share of procedures incorporating cerebral protection devices was 3.8%. Patients receiving cerebral protection devices were at increased operative risk (European System for Cardiac Operative Risk Evaluation score 13.8 vs. 14.7; p < 0.001) but of lower age (81.1 vs. 80.6 years; p = 0.001). To compare outcomes that may be related to the use of cerebral protection devices, a propensity score comparison was performed. The use of a cerebral protection device did not reduce the risk for stroke (adjusted risk difference [aRD]: +0.88%; 95% confidence interval [CI]: -0.07% to 1.83%; p = 0.069) or the risk for developing delirium (aRD: +1.31%; 95% CI: -0.28% to 2.89%; p = 0.106) as a sign of acute brain failure. Although brain damage could not be prevented, in-hospital mortality was lower in the group receiving a cerebral protection device (aRD: -0.76%; 95% CI: -1.46% to -0.06%; p = 0.034). CONCLUSIONS In this large national database, cerebral embolic protection devices were infrequently used during TAVR procedures. Device use was associated with lower mortality but not a reduction in stroke or delirium. Future studies are needed to confirm these findings.

Abstract
Background A central element in the management of cardiogenic shock (CS) comprises mechanical circulatory support (MCS) systems to maintain cardiac output (CO). This study aims to quantify incidence, outcome and influence of MCS in CS over the last decade. Methods All patients hospitalized with CS in a tertiary university hospital in Germany between 2007 and 2017 were identified utilizing the international coding system ICD-10 with code R57.0. Application of MCS was identified via German procedure classification codes (OPS). Results 383,983 cases of cardiogenic shock were reported from 2007 to 2017. Patients had a mean age of 71 years and 38.5% were female. The incidence of CS rose by 65.6% from 26,828 cases in 2007 (33.1 per 100,000 person-years, hospital survival 39.2%) to 44,425 cases in 2017 (53.7 per 100,000 person-years, survival 41.2%). In 2007, 16.0% of patients with CS received MCS (4.6 per 100,000 person-years, survival 46.6%), dropping to 13.9% in 2017 (6.6 per 100,000 person-years, survival 38.6%). Type of MCS changed over the years, with decreasing use of the intra-aortic balloon pump (IABP), an increase in extracorporeal membrane oxygenation (VA-ECMO) and percutaneous ventricular assist device (pVAD) usage. Significant differences regarding in-hospital survival were observed between the devices (survival: overall: 40.2%; medical treatment = 39.5%; IABP = 49.5%; pVAD = 36.2%; VA-ECMO = 30.5%; p < 0.001). Conclusions The incidence of CS is increasing, but hospital survival remains low. MCS was used in a minority of patients, and the percentage of MCS usage in CS has decreased. The use rates of the competing devices change over time. Graphical Abstract ![]()

Abstract
Abstract
Introduction and aim
Current emergency treatment options for severe aortic valve stenosis include surgical aortic valve replacement (SAVR), transcatheter aortic valve replacement (TAVR) and balloon valvuloplasty (BV). So far no larger patient population has been evaluated regarding clinical characteristics and outcomes. Therefore we aimed to describe the use and outcome of the three therapy options in a broad registry study.
Method and results
Using German nationwide electronic health records, we evaluated emergency admissions of symptomatic patients with severe aortic valve stenosis between 2014 and 2017. Patients were grouped according to SAVR, TAVR or BV only treatments. Primary outcome was in-hospital mortality. Secondary outcomes were stroke, acute kidney injury, periprocedural pacemaker implantation, delirium and prolonged mechanical ventilation >48 hours. Stepwise multivariable logistic regression analyses including baseline characteristics were performed to assess outcome risks.
8,651 patients with emergency admission for severe aortic valve stenosis were identified. The median age was 79 years and comorbidities included NYHA classes III-IV (52%), coronary artery disease (50%), atrial fibrillation (41%) and diabetes mellitus (33%). Overall in-hospital mortality was 6.2% during a mean length of stay of 22±15 days. TAVR was the most common treatment (6,357 [73.5%]), followed by SAVR (1,557 [18%]) and BV (737 8.5%]).
Patients who were treated with TAVR or BV were significantly older than patients with SAVR (mean age 81.3±6.5 and 81.2±6.9 versus 67.2±11.0 years, p<0.001), had more relevant comorbidities (coronary artery disease 52–91% vs. 21.8%; p<0.001), worse NYHA classes III-IV (55–65% vs. 34.5%; p<0.001) and higher EuroSCORES (24.6±14.3 and 23.4±13.9 vs. 9.5±7.6; p<0.001) than SAVR patients. Patients treated with BV only had the highest in-hospital mortality compared with TAVR or SAVR (20.9% vs. 5.1 and 3.5%; p<0.001).
Compared with BV only, SAVR patients (adjusted odds ratio [aOR] 0.25; 95% confidence interval [CI] 0.14–0.46; p<0.001) and TAVR patients (aOR 0.37; 95% CI 0.28–0.50; p<0.001) had a lower risk for in-hospital mortality.
Conclusion
In-hospital mortality for emergency patients with symptomatic severe aortic valve stenosis is high. Our results showed that BV only therapy was associated with highest mortality, which is in line with current research. Yet, there is a trend towards more TAVR interventions and this study might imply that balloon valvuloplasty alone is insufficient. The role of BV as a bridging strategy to TAVR or SAVR needs to be further investigated.

Abstract
Abstract
Background
Percutaneous coronary intervention (PCI) is an established procedure, but recent studies analyzing the indication for stenting are going to change clinical practice. Previous studies suggested that hospital volume is inversely related to in-hospital mortality but its impact on likelihood of stent implantation and the number of stents remains unclear.
Purpose
There is a conflict of objectives between nationwide care including short transfer and intervention times and a few large centers with maximum technology and experience. We examine the effect of hospital volume on in-hospital mortality, likelihood of stent implantation, number of stents, length of hospital stay, and reimbursement in a recent nationwide cohort from Germany.
Methods
Using German national electronic health records, all patients who underwent coronary angiography with a documented coronary artery disease were identified by ICD and OPS codes. Risk-adjustment was applied using a predefined set of patient characteristics to account for differences in the risk factor composition of the patient populations between centers.
Results
In 2017, a total of 528,188 patients with a documented coronary artery disease underwent coronary angiography in Germany. Mean age was 69.8 years and 29.3% of patients were female. 55% of all patients received PCI, with a mean number of 1.01 stents implanted per patient. In-hospital mortality was 2.9%, length of hospital stay was 6.5 days and mean reimbursement was €5,531. Multivariable regression analyses showed a positive linear association between hospital volumes and the likelihood of stent implantation (p=0.003) as well as the number of implanted stents (p=0.020). No association was found between hospital volumes and in-hospital mortality (p=0.105), length of hospital stay (p=0.201) or reimbursement (p=0.108). Inspection of the non-linear impact of procedure volumes on stent implantation practices indicates a ceiling effect in the volume-outcome relationship: implantation likelihood and number of stents per patient are lowest in centers with less than 100 procedures per year (34.4% and 0.62, respectively). Then, implantation likelihood and number of stents constantly increase until the volume category of 500 procedures per year and center. For centers with >500 procedures per year, the likelihood of stent implantation and the number of implanted stents remained relatively constant (about 60% and 1.07, respectively).
Conclusion
Patients undergoing coronary angiography in low-volume centers are less frequently subject to PCI but at comparable risk for in-hospital mortality. Furthermore, the data suggest that more complex cases are treated in high volume centers with consistent mortality rates and thus constant safety is ensured in high volume hospitals. Thresholds are discussed.

Abstract
AIM The present study analyzes in depth the impact of different calcification patterns on disturbances of the conduction system in transcatheter aortic valve replacement (TAVR) patients. METHODS AND RESULTS A total of 169 preprocedural TAVR multislice computed tomography scans from consecutive transfemoral (TF) TAVRs performed between 2014 and 2017 using either Edwards SAPIEN or Medtronic Evolut R valves were retrospectively evaluated. The volume, distribution, and orientation of annular and valvular aortic valve calcification were measured and their impact on postoperative conduction disturbances was determined using linear and logistic regression analyses. The total volume of calcification and distribution at the aortic annulus or valve did not influence the conduction system. Oval calcification of the left aortic cusp was independently associated with an elevated risk for an increase in atrioventricular block degree (+0.6, p = 0.03). Moreover, orthogonal calcifications at the level of the aortic annulus were associated with an increased risk for QRS prolongation (+26 ms, p = 0.004) and an increased risk for permanent pacemaker implantation (OR 4.3, p = 0.03) after TF TAVR. This was more pronounced in patients undergoing TF TAVR using a balloon-expandable Edwards SAPIEN 3 valve (QRS +38.195 ms, p < 0.001; OR permanent pacemaker 15.48, p = 0.013). CONCLUSION Orthogonal annular calcification confers an increased risk for conduction disturbances after TAVR. This is even more pronounced after implantation of balloon-expandable valves.

Abstract
AIMS Short-QT syndrome 1 (SQT1) is an inherited channelopathy with accelerated repolarization due to gain-of-function in HERG/IKr. Patients develop atrial fibrillation, ventricular tachycardia (VT), and sudden cardiac death with pronounced inter-individual variability in phenotype. We generated and characterized transgenic SQT1 rabbits and investigated electrical remodelling. METHODS AND RESULTS Transgenic rabbits were generated by oocyte-microinjection of β-myosin-heavy-chain-promoter-KCNH2/HERG-N588K constructs. Short-QT syndrome 1 and wild type (WT) littermates were subjected to in vivo ECG, electrophysiological studies, magnetic resonance imaging, and ex vivo action potential (AP) measurements. Electrical remodelling was assessed using patch clamp, real-time PCR, and western blot. We generated three SQT1 founders. QT interval was shorter and QT/RR slope was shallower in SQT1 than in WT (QT, 147.8 ± 2 ms vs. 166.4 ± 3, P < 0.0001). Atrial and ventricular refractoriness and AP duration were shortened in SQT1 (vAPD90, 118.6 ± 5 ms vs. 154.4 ± 2, P < 0.0001). Ventricular tachycardia/fibrillation (VT/VF) inducibility was increased in SQT1. Systolic function was unaltered but diastolic relaxation was enhanced in SQT1. IKr-steady was increased with impaired inactivation in SQT1, while IKr-tail was reduced. Quinidine prolonged/normalized QT and action potential duration (APD) in SQT1 rabbits by reducing IKr. Diverse electrical remodelling was observed: in SQT1, IK1 was decreased-partially reversing the phenotype-while a small increase in IKs may partly contribute to an accentuation of the phenotype. CONCLUSION Short-QT syndrome 1 rabbits mimic the human disease phenotype on all levels with shortened QT/APD and increased VT/VF-inducibility and show similar beneficial responses to quinidine, indicating their value for elucidation of arrhythmogenic mechanisms and identification of novel anti-arrhythmic strategies.

Abstract
Abstract
Background Atrial fibrillation (AF) is a risk factor for poor postoperative outcome after transfemoral transcatheter aortic valve replacement (TF-TAVR). The present study analyses the outcomes after TF-TAVR in patients with or without AF and identifies independent predictors for in-hospital mortality in clinical practice.
Methods and Results Among all 57,050 patients undergoing isolated TF-TAVR between 2008 and 2016 in Germany, 44.2% of patients (n = 25,309) had AF. Patients with AF were at higher risk for unfavorable in-hospital outcome after TAVR. Including all baseline characteristics for a risk-adjusted comparison, AF was an independent risk factor for in-hospital mortality after TAVR. Among patients with AF, EuroSCORE, New York Heart Association classification class, or renal disease had only moderate effects on mortality, while the occurrence of postprocedural stroke or moderate to major bleeding substantially increased in-hospital mortality (odds ratio [OR] 3.35, 95% confidence interval [CI] 2.61–4.30, p < 0.001 and OR 3.12, 95% CI 2.68–3.62, p < 0.001). However, the strongest independent predictor for in-hospital mortality among patients with AF was severe bleeding (OR 18.00, 95% CI 15.22–21.30, p < 0.001).
Conclusion The present study demonstrates that the incidence of bleeding defines the in-hospital outcome of patients with AF after TF-TAVR. Thus, the periprocedural phase demands particular care in bleeding prevention.

Abstract
Background Prone positioning (PP) has shown to improve survival in patients with severe acute respiratory distress syndrome (ARDS). To this point, it is unclear if PP is also beneficial for ARDS patients treated with veno-venous extracorporeal membrane oxygenation (VV ECMO) support. Methods We report retrospective data of a single-centre registry of patients with severe ARDS requiring VV ECMO support between October 2010 and May 2018. Patients were allocated to the PP group if PP was performed during VV ECMO treatment or the supine positioning group. VV ECMO weaning success and hospital survival were analysed before and after propensity score matching. Results A total of 158 patients could be analysed, and 38 patients (24.1%) received PP. There were no significant differences in VV ECMO weaning rate (47.4% vs. 46.7%, p = 0.94) and hospital survival (36.8% vs. 36.7%, p = 0.98) between the prone and supine groups, respectively. The analysis of 38 propensity score matched pairs also showed no difference in hospital survival (36.8% vs. 36.8%, p = 1.0) or VV ECMO weaning rate (47.4% vs. 44.7%, p = 0.82). Hospital survival was superior in the subgroup of patients treated with early PP (cutoff < 17 h via Youden’s Index) as compared to late or no PP (81.8% vs. 33.3%, p = 0.02). Conclusion In this propensity score matched cohort of severe ARDS patients requiring VV ECMO support, prone positioning at any time was not associated with improved weaning or survival. However, early initiation of prone positioning was linked to a significant reduction of hospital mortality.

Abstract
Background Transfemoral transcatheter aortic valve replacement (TF‐TAVR) is recommended for patients suffering from aortic valve stenosis at increased operative risk. Beyond that, patients with different comorbidities could benefit from TF‐TAVR. The present study compares real‐world in‐hospital outcomes of surgical aortic valve replacement and TF‐TAVR. Methods and Results For all 33 789 isolated TF‐TAVR and surgical aortic valve replacement procedures performed in Germany in 2014 and 2015, comorbidities and in‐hospital outcomes were identified by International Classification of Diseases (ICD)‐ and OPS (Operation and procedure key)‐codes. Patients undergoing TF‐TAVR were older and at increased estimated risk. Outcomes were risk‐adjusted to allow comparison. TF‐TAVR was associated with a lower risk for acute kidney injuries (odds ratio [OR] 0.62, P<0.001), for bleeding (OR 0.17, P<0.001), and for prolonged mechanical ventilation (>48 hours, OR 0.21, P<0.001). Risk for stroke was similar (OR 1.07, P=0.558). As expected, the risk for pacemaker implantations was higher after TF‐TAVR (OR 4.61, P<0.001). In all patients, none of the treatment strategies had a clear advantage on the risk for in‐hospital mortality (OR 0.83, P=0.068). However, in patients aged >80 years and at high operative risk undergoing TF‐TAVR in‐hospital mortality was lower (TF‐TAVR versus surgical aortic valve replacement 80–84, OR 0.55; P=0.002; ≥85 years, OR 0.42, P=0.006; EuroSCORE (European System for Cardiac Operative Risk Evaluation) >9: OR 0.62, P=0.001). TF‐TAVR was superior in patients with renal failure and in NYHA (New York Heart Association)‐Class III/IV. Other risk groups were not found to be factors favoring a treatment strategy. Conclusions The present study indicates a superiority of TF‐TAVR in clinical practice for patients at increased operative risk, aged >80 years, in NYHA‐Class III/IV, and with renal failure.

Abstract
Background and Purpose Reliable prediction of pro‐arrhythmic side effects of novel drug candidates is still a major challenge. Although drug‐induced pro‐arrhythmia occurs primarily in patients with pre‐existing repolarisation disturbances, healthy animals are employed for pro‐arrhythmia testing. To improve current safety screening, transgenic long QT (LQTS) rabbit models with impaired repolarisation reserve were generated by overexpressing loss‐of‐function mutations of human HERG (HERG‐G628S, loss of IKr; LQT2), KCNE1 (KCNE1‐G52R, decreased IKs; LQT5), or both transgenes (LQT2‐5) in the heart. Experimental Approach Effects of K+ channel blockers on cardiac repolarisation and arrhythmia susceptibility were assessed in healthy wild‐type (WT) and LQTS rabbits using in vivo ECG and ex vivo monophasic action potential and ECG recordings in Langendorff‐perfused hearts. Key Results LQTS models reflect patients with clinically “silent” (LQT5) or “manifest” (LQT2 and LQT2‐5) impairment in cardiac repolarisation reserve: they were more sensitive in detecting IKr‐blocking (LQT5) or IK1/IKs‐blocking (LQT2 and LQT2‐5) properties of drugs compared to healthy WT animals. Impaired QT‐shortening capacity at fast heart rates was observed due to disturbed IKs function in LQT5 and LQT2‐5. Importantly, LQTS models exhibited higher incidence, longer duration, and more malignant types of ex vivo arrhythmias than WT. Conclusion and Implications LQTS models represent patients with reduced repolarisation reserve due to different pathomechanisms. As they demonstrate increased sensitivity to different specific ion channel blockers (IKr blockade in LQT5 and IK1 and IKs blockade in LQT2 and LQT2‐5), their combined use could provide more reliable and more thorough prediction of (multichannel‐based) pro‐arrhythmic potential of novel drug candidates.

Abstract
Background The introduction of percutaneous mitral valve (MV) repair had an effect on clinical practice in comparison with surgical MV repair. Complete nationwide data are useful in examining how the introduction of a new technique influences clinical practice. Methods We analyzed procedural numbers, patient characteristics, and in-hospital outcomes for all percutaneous edge-to-edge and surgical MV reconstruction procedures performed in Germany between 2009 and 2015. Results 12,664 percutaneous edge-to-edge and 22,825 surgical MV reconstructions were recorded. Numbers increased steadily, albeit more rapidly in the percutaneous edge-to-edge group (108–4079 vs. 2923–3603 with surgical MV reconstruction). Patients with percutaneous edge-to-edge MV reconstruction were older (75.6 ± 8.8 vs 61.6 ± 13.4 years, P < 0.001) and at higher operative risk (estimated logistic EuroSCORE 13.2% vs. 4.7%, P < 0.001) compared to those undergoing surgery. However, in-hospital mortality did not differ (2.9% vs. 2.8%; P = 0.395). This was also true for the subset of 2103 patients at intermediate operative risk as defined by a logistic EuroSCORE ≥ 4% and ≤ 9%. Of note, complication rates (except acute kidney injury) were more favorable in patients undergoing percutaneous edge-to-edge reconstruction. Conclusions Percutaneous edge-to-edge MV reconstruction has markedly changed clinical practice of MR therapy in Germany. Annual overall procedural numbers more than doubled, with a massive increase in percutaneous edge-to-edge procedures. Our data demonstrate its use mainly in high-risk patients and prove the favorable safety profile of this novel technique, with low in-hospital mortality and complication rates.

Abstract
BACKGROUND If the transfemoral access is not feasible, a transapical access or surgical aortic valve replacement (SAVR) are alternatives for patients with aortic valve stenosis. OBJECTIVES To identify patient groups who benefit from SAVR or transapical transcatheter aortic valve replacement (TA-TAVR), we compared in-hospital outcomes of patients in a nationwide dataset. METHODS We identified 19,016 isolated SAVR and 6432 TA-TAVR performed in Germany from 2014 to 2016. We adjusted for risk factors using a covariate- and propensity-adjusted analysis. RESULTS Patients undergoing TA-TAVR were older, had more comorbidities, and accordingly greater estimated operative risk (logistic European System for Cardiac Operative Risk Evaluation 5.3 vs 17.0, P < .001). However, adjusted risk for in-hospital complications such as stroke, acute kidney injury, relevant bleeding, and prolonged mechanical ventilation >48 hours was lower in patients undergoing TA-TAVR (all P < .001). When we compared in-hospital mortality of all patients undergoing either TA-TAVR or SAVR, neither treatment strategy had a clear advantage (covariate-adjusted odds ratio [caOR], 1.13, P = .251; propensity-adjusted OR [paOR], 1.12, P = .309). Two patient subgroups seem to benefit more from SAVR than TA-TAVR: patients <75 years (caOR, 1.29, P = .237; paOR, 2.12, P = .001) and those with European System for Cardiac Operative Risk Evaluation 4-9 (caOR, 1.32, P = .114; paOR, 1.43, P = .041). Female patients had a tendency toward lower risk for in-hospital mortality when undergoing SAVR (caOR, 1.42, P = .030). In patients with chronic renal failure, TA-TAVR was superior (caOR, 0.56, P = .039, P = .040). CONCLUSIONS Patients <75 years and those at low operative risk who underwent SAVR had lower in-hospital mortality than those undergoing TA-TAVR. Patients with chronic renal failure who underwent TA-TAVR had lower in hospital mortality than those that underwent SAVR.

Abstract
ObjectiveTranscatheter aortic valve implantation (TAVI) is the most common aortic valve replacement in Germany. Since 2015, to ensure high-quality procedures, hospitals in Germany and other countries that meet the minimum requirement of 50 interventions per centre are being certified to perform TAVI. This study analyses the impact of these requirements on case number and in-hospital outcomes.MethodsAll isolated TAVI procedures and in-hospital outcomes between 2008 and 2016 were identified by International Classification of Diseases (ICD) and the German Operation and Procedure Classification codes.Results73 467 isolated transfemoral and transapical TAVI procedures were performed in Germany between 2008 and 2016. During this period, the number of TAVI procedures per year rose steeply, whereas the overall rates of hospital mortality and complications declined. In 2008, the majority of procedures were performed in hospitals with fewer than 50 cases per year (54.63%). Until 2014, the share of patients treated in low-volume centres constantly decreased to 5.35%. After the revision of recommendations, it further declined to 1.99%. In the 2 years after the introduction of the minimum requirements on case numbers, patients were at decreased risk for in-hospital mortality when treated in a high-volume centre (risk-adjusted OR 0.62, p=0.012). The risk for other in-hospital outcomes (stroke, permanent pacemaker implantation and bleeding events) did not differ after risk adjustment (p=0.346, p=0.142 and p=0.633).ConclusionA minimum volume of 50 procedures per centre and year appears suitable to allow for sufficient routine and thus better in-hospital outcomes, while ensuring nationwide coverage of TAVI procedures.

Abstract
Aims Patients with postoperative delirium (POD) after transcatheter aortic valve replacement (TAVR) are ventilated and hospitalized longer and suffer increased in-hospital mortality. This study hypothesized that a minimalistic approach with conscious sedation during transfemoral aortic valve replacement (TF-AVR) protects against delirium, time of mechanical ventilation, and increased length of stay in intensive care unit (ICU) compared to intubation anaesthesia. Methods and results 308 patients which underwent TF-AVR in our centre between 01/2013 and 08/2017 were retrospectively evaluated regarding postoperative delirium, time of mechanical ventilation, and days in ICU. TF-AVR was performed with intubation anaesthesia in 245 patients and with conscious sedation in 63. The operative risk estimated by the logEUROScore was similar in both groups (intubation: 13.28 +/-9.06%, conscious sedation: 12.24 +/-6.77%, p = 0.395). In the conscious sedation group procedure duration was shorter (0.61 +/-0.91h vs. 1.75 +/-0.96h, p<0.001). The risk for intraprocedural complications was not influenced by the anaesthesia method (OR conscious sedation instead of intubation 1.66, p = 0.117), but days on ICU (-2.21 days, p<0.0001) and minutes of mechanical ventilation (-531.2 min, p < 0.0001) were reduced. Furthermore, the risk of POD was decreased when TF-AVR was performed under conscious sedation (6.35% vs. 18.18%, OR 0.29, p = 0.021). Conclusions Time of mechanical ventilation, risk of POD, and days on ICU were substantially reduced in patients who underwent TF-AVR under conscious sedation. Our data suggest that TF-AVR with conscious sedation is safe with a beneficial postoperative course in clinical practice, and should be considered the favoured approach.

Abstract
OBJECTIVE Aim of this study was to investigate predictors of survival in unstable patients with high SYNTAX-1-score. BACKGROUND In significant unprotected left main coronary artery (ULMCA) stenosis, treatment options include percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). While CABG is recommended for stable patients with ULMCA stenosis and a SYNTAX-1-score > 32, PCI may be preferable in unstable or high operative risk patients. METHODS Retrospective single-center all-comers registry study. RESULTS A total of 142 patients underwent ULMCA-PCI (~72.9 years, 23.2% females, 54.2% survival in 2-year follow-up), 84 of whom had a SYNTAX-1 > 32 (37.4 ± 12.8). Patients in the high-SYNTAX-1-group (score > 32) were more often in an acute condition compared to low-SYNTAX-2-group (score ≤ 32) including acute myocardial infarction (76.2% vs. 57.4%, p = .024), cardiogenic shock (48.2% vs. 14.8%, p = .001), or need for mechanical support (36.1% vs. 11.1%, p = .001). Survival was predicted by the acute condition including cardiogenic shock (OR 0.06 and 0.05) and myocardial infarction (OR 0.03 and 0.34) in both groups. Performance of the SYNTAX-1-score was limited in our patient collective in both groups (c-index 0.65 vs. 0.63) while SYNTAX-2-PCI-score performed better (c-index 0.67 vs. 0.67). EuroScore II had the best discriminative ability (c-index 0.87 vs. 0.78). CONCLUSIONS The majority of patients undergoing ULMCA-PCI presented in acute conditions with high SYNTAX-1-score, and is therefore underrepresented in clinical trials. Prognosis was best predicted by the acute condition and the EuroScore II. These data suggest that therapy in unstable patients should be guided by clinical condition over the anatomical SYNTAX-1-score.

Abstract
Background Inflammation drives atherosclerosis and its complications. Anti-inflammatory therapy with interleukin 1 beta (IL-1β) antibody reduces cardiovascular events in patients with elevated high-sensitive C-reactive protein (hsCRP). This study aims to identify the share of patients with coronary heart disease (CHD) and residual inflammation who may benefit from anti-inflammatory therapy. Methods hsCRP and low-density lipoprotein (LDL) levels were determined in 2741 all-comers admitted to the cardiological ward of our tertiary referral hospital between June 2016 and June 2018. Patients without CHD, with acute coronary syndrome, chronic or recurrent systemic infection, use of immunosuppressant or anti-inflammatory agents, chronic inflammatory diseases, chemotherapy, terminal organ failure, traumatic injury and pregnancy were excluded. Results 856 patients with stable CHD were included. 42.7% of those had elevated hsCRP ≥ 2 mg/l. Within the group of patients with LDL-cholesterol < 70 mg/dl, 30.9% shared increased hsCRP indicating residual inflammation. After multivariate adjusted backward selection elevated Lipoprotein (a) (OR 1.61, p = 0.048), elevated proBNP (OR 2.57, p < 0.0001), smoking (OR 1.70, p = 0.022), and obesity (OR 2.28, p = 0.007) were associated with elevated hsCRP. In contrast, the use of ezetimibe was associated with normal hsCRP (OR 0.51, p = 0.014). In the subgroup of patients with on-target LDL-cholesterol < 70 mg/dl, backward selection identified elevated proBNP (OR 3.49, p = 0.007) as independent predictor of elevated hsCRP in patients with LDL-cholesterol < 70 mg/dl. Conclusion One-third of all-comers patients with CHD showed increased levels of hsCRP despite a LDL-cholesterol < 70 mg/dl potentially qualifying for an anti-inflammatory therapy. Elevated proBNP is an independent risk factor for hsCRP elevation. Graphic abstract ![]()

Abstract
X-ray fluoroscopy is the gold standard for coronary diagnostics and intervention. Magnetic resonance imaging is a radiation-free alternative to x-ray with excellent soft tissue contrast in arbitrary slice orientation. Here, we assessed real-time MRI-guided coronary interventions from femoral access using newly designed MRI technologies. Six Goettingen minipigs were used to investigate coronary intervention using real-time MRI. Catheters were custom-designed and equipped with an active receive tip-coil to improve visibility and navigation capabilities. Using modified standard clinical 5 F catheters, intubation of the left coronary ostium was successful in all animals. For the purpose of MR-guided coronary interventions, a custom-designed 8 F catheter was used. In spite of the large catheter size, and therefore limited steerability, intubation of the left coronary ostium was successful in 3 of 6 animals within seconds. Thereafter, real-time guided implantation of a non-metallic vascular scaffold into coronary arteries was possible. This study demonstrates that real-time MRI-guided coronary catheterization and intervention via femoral access is possible without the use of any contrast agents or radiation, including placement of non-metallic vascular scaffolds into coronary arteries. Further development, especially in catheter and guidewire technology, will be required to drive forward routine MR-guided coronary interventions as an alternative to x-ray fluoroscopy.

Abstract
Aortic stenosis (AS) is the most common valvular heart disease, with a dismal prognosis when untreated. Recommended therapy is surgical (SAVR) or transcatheter (TAVR) aortic valve replacement. Based on a retrospective cohort of isolated SAVR and TAVR procedures performed in Germany in 2015 (N = 17,826), we examine the impact of treatment selection on in-hospital mortality and total in-hospital costs for a variety of at-risk populations. Since patients were not randomized to the two treatment options, the two endpoints in-hospital mortality and reimbursement are analyzed using logistic and linear regression models with 20 predefined patient characteristics as potential confounders. Incremental cost-effectiveness ratios were calculated as a ratio of the risk-adjusted reimbursement and mortality differences with 95% confidence intervals obtained by Fieller's theorem. Our study shows that TF-TAVR is more costly that SAVR and that cost differences between the procedures vary little between patient groups. Results regarding in-hospital mortality are mixed. SAVR is the predominant procedure among younger patients. For patients older than 85 years or at intermediate and higher pre-operative risk TF-TAVR seems to be the treatment of choice. Incremental cost-effectiveness ratios (ICER) are most favorable for patients older than 85 years (ICER €154,839, 95% CI €89,163-€302,862), followed by patients at higher pre-operative risk (ICER €413,745, 95% CI €258,027-€952,273). A hypothetical shift from SAVR towards TF-TAVR among patients at intermediate pre-operative risk is associated with a less favorable ICER (€1,486,118, 95% CI €764,732-€23,692,323), as the risk-adjusted mortality benefit is relatively small (- 0.97% point), while the additional reimbursement is still eminent (+€14,464). From a German healthcare system payer's perspective, the additional costs per life saved due to TAVR are most favorable for patients older than 85 and/or at higher pre-operative risk.

Abstract
Aims
Women with long QT syndrome 2 (LQT2) have a particularly high postpartal risk for lethal arrhythmias. We aimed at investigating whether oxytocin and prolactin contribute to this risk by affecting repolarization.
Methods and results
In female transgenic LQT2 rabbits (HERG-G628S, loss of IKr), hormone effects on QT/action potential duration (APD) were assessed (0.2–200 ng/L). Hormone effects (200 ng/L) on ion currents and cellular APD were determined in transfected cells and LQT2 cardiomyocytes. Hormone effects on ion channels were assessed with qPCR and western blot. Experimental data were incorporated into in silico models to determine the pro-arrhythmic potential. Oxytocin prolonged QTc and steepened QT/RR-slope in vivo and prolonged ex vivo APD75 in LQT2 hearts. Prolactin prolonged APD75 at high concentrations. As underlying mechanisms, we identified an oxytocin- and prolactin-induced acute reduction of IKs-tail and IKs-steady (−25.5%, oxytocin; −13.3%, prolactin, P < 0.05) in CHO-cells and LQT2-cardiomyocytes. IKr currents were not altered. This oxytocin-/prolactin-induced IKs reduction caused APD90 prolongation (+11.9%/+13%, P < 0.05) in the context of reduced/absent IKr in LQT2 cardiomyocytes. Hormones had no effect on IK1 and ICa,L in cardiomyocytes. Protein and mRNA levels of CACNA1C/Cav1.2 and RyR2 were enhanced by oxytocin and prolactin. Incorporating these hormone effects into computational models resulted in reduced repolarization reserve and increased propensity to pro-arrhythmic permanent depolarization, lack of capture and early afterdepolarizations formation.
Conclusions
Postpartum hormones oxytocin and prolactin prolong QT/APD in LQT2 by reducing IKs and by increasing Cav1.2 and RyR2 expression/transcription, thereby contributing to the increased postpartal arrhythmic risk in LQT2.

Abstract
INTRODUCTION Treatment of aortic valve stenosis has been changing since the introduction of transcatheter aortic valve replacement (TAVR). The present study investigates the treatment of aortic valve stenosis in a real-world population 2014 and 2015 in Germany. METHODS Patient characteristics and in-hospital outcomes of all 38 414 isolated surgical aortic valve replacements (SAVR) or TAVR were analyzed. RESULTS Since 2014 more TAVR than SAVR were performed in Germany. Overall interventions on the aortic valve increases: from 10 858 in 2009 to 19 929 in 2015. In 2015 patients > 75 were mainly treated with transfemoral (TF) TAVR. SAVR was performed in 474 patients over 80 years (for comparison: TF-TAVR: 7519; transapical (TA) TAVR: 1192). Patients treated with TAVR were older, more often female, and had more co-morbidities. Consequently, they were at higher operative risk. Overall in-hospital mortality was 2 % after SAVR, 3 % after TF-TAVR, and 6 % after TA-TAVR. Stroke rates were similar. Relevant bleeding events occurred after SAVR and TA-TAVR in 9 % and 8 % respectively and 3 % after TF-TAVR. 66 % of patients after TF-TAVR and 40 % after SAVR were discharged home. DISCUSSION TF-TAVR has become the most often performed therapy for patients > 75. Despite a higher operative risk, patients can be treated safely with TF-TAVR.
