Abstract
BACKGROUND Scarce data exist on the evolution of device-related thrombus (DRT) after left atrial appendage closure (LAAC). OBJECTIVES This study sought to assess the incidence, predictors, and clinical impact of persistent and recurrent DRT in LAAC recipients. METHODS Data were obtained from an international multicenter registry including 237 patients diagnosed with DRT after LAAC. Of these, 214 patients with a subsequent imaging examination after the initial diagnosis of DRT were included. Unfavorable evolution of DRT was defined as either persisting or recurrent DRT. RESULTS DRT resolved in 153 (71.5%) cases and persisted in 61 (28.5%) cases. Larger DRT size (OR per 1-mm increase: 1.08; 95% CI: 1.02-1.15; P = 0.009) and female (OR: 2.44; 95% CI: 1.12-5.26; P = 0.02) were independently associated with persistent DRT. After DRT resolution, 82 (53.6%) of 153 patients had repeated device imaging, with 14 (17.1%) cases diagnosed with recurrent DRT. Overall, 75 (35.0%) patients had unfavorable evolution of DRT, and the sole predictor was average thrombus size at initial diagnosis (OR per 1-mm increase: 1.09; 95% CI: 1.03-1.16; P = 0.003), with an optimal cutoff size of 7 mm (OR: 2.51; 95% CI: 1.39-4.52; P = 0.002). Unfavorable evolution of DRT was associated with a higher rate of thromboembolic events compared with resolved DRT (26.7% vs 15.1%; HR: 2.13; 95% CI: 1.15-3.94; P = 0.02). CONCLUSIONS About one-third of DRT events had an unfavorable evolution (either persisting or recurring), with a larger initial thrombus size (particularly >7 mm) portending an increased risk. Unfavorable evolution of DRT was associated with a 2-fold higher risk of thromboembolic events compared with resolved DRT.

Abstract
BACKGROUND Device-related thrombus (DRT) has been considered an Achilles' heel of left atrial appendage occlusion (LAAO). However, data on DRT prediction remain limited. OBJECTIVES This study constructed a DRT registry via a multicenter collaboration aimed to assess outcomes and predictors of DRT. METHODS Thirty-seven international centers contributed LAAO cases with and without DRT (device-matched and temporally related to the DRT cases). This study described the management patterns and mid-term outcomes of DRT and assessed patient and procedural predictors of DRT. RESULTS A total of 711 patients (237 with and 474 without DRT) were included. Follow-up duration was similar in the DRT and no-DRT groups, median 1.8 years (interquartile range: 0.9-3.0 years) versus 1.6 years (interquartile range: 1.0-2.9 years), respectively (P = 0.76). DRTs were detected between days 0 to 45, 45 to 180, 180 to 365, and >365 in 24.9%, 38.8%, 16.0%, and 20.3% of patients. DRT presence was associated with a higher risk of the composite endpoint of death, ischemic stroke, or systemic embolization (HR: 2.37; 95% CI, 1.58-3.56; P < 0.001) driven by ischemic stroke (HR: 3.49; 95% CI: 1.35-9.00; P = 0.01). At last known follow-up, 25.3% of patients had DRT. Discharge medications after LAAO did not have an impact on DRT. Multivariable analysis identified 5 DRT risk factors: hypercoagulability disorder (odds ratio [OR]: 17.50; 95% CI: 3.39-90.45), pericardial effusion (OR: 13.45; 95% CI: 1.46-123.52), renal insufficiency (OR: 4.02; 95% CI: 1.22-13.25), implantation depth >10 mm from the pulmonary vein limbus (OR: 2.41; 95% CI: 1.57-3.69), and non-paroxysmal atrial fibrillation (OR: 1.90; 95% CI: 1.22-2.97). Following conversion to risk factor points, patients with ≥2 risk points for DRT had a 2.1-fold increased risk of DRT compared with those without any risk factors. CONCLUSIONS DRT after LAAO is associated with ischemic events. Patient- and procedure-specific factors are associated with the risk of DRT and may aid in risk stratification of patients referred for LAAO.

Abstract
Potassium is the predominant intracellular cation, with its extracellular concentrations maintained between 3. 5 and 5 mM. Among the different potassium disorders, hypokalaemia is a common clinical condition that increases the risk of life-threatening ventricular arrhythmias. This review aims to consolidate pre-clinical findings on the electrophysiological mechanisms underlying hypokalaemia-induced arrhythmogenicity. Both triggers and substrates are required for the induction and maintenance of ventricular arrhythmias. Triggered activity can arise from either early afterdepolarizations (EADs) or delayed afterdepolarizations (DADs). Action potential duration (APD) prolongation can predispose to EADs, whereas intracellular Ca2+ overload can cause both EADs and DADs. Substrates on the other hand can either be static or dynamic. Static substrates include action potential triangulation, non-uniform APD prolongation, abnormal transmural repolarization gradients, reduced conduction velocity (CV), shortened effective refractory period (ERP), reduced excitation wavelength (CV × ERP) and increased critical intervals for re-excitation (APD-ERP). In contrast, dynamic substrates comprise increased amplitude of APD alternans, steeper APD restitution gradients, transient reversal of transmural repolarization gradients and impaired depolarization-repolarization coupling. The following review article will summarize the molecular mechanisms that generate these electrophysiological abnormalities and subsequent arrhythmogenesis.

Abstract
BACKGROUND Outcome data following transcatheter mitral valve repair (TMVR) with the MITRACLIP® device are scarce outside the pivotal randomized controlled trials. METHODS The Nationwide Readmission Data base (NRD) was utilized for years 2013-2017 to identify the study population. Thirty-day readmission pattern, in-hospital complications, causes of readmissions, and multivariate predictors for readmission, complications and mortality were explored. RESULTS We noted a total of 14,647 index admissions related to MITRACLIP of which 48% of procedures were performed at high volume centers (Annual hospital volume ≥ 25). A total of 15% of patients were readmitted within 30 days of discharge most frequently due to cardiac causes. Approximately 33% of patients were discharged within 24 h of the procedure. The in-hospital mortality rate was 2.8% and in-hospital complication rate was 14.6%. The most common complications were cardiac complications (8.2%), bleeding related complications (5.9%) and vascular complications (0.65%). On multivariate modeling, female sex, CHF, Atrial fibrillation, prior PCI, COPD, CKD, transfer to skilled nursing facility, length of stay ≥2 days were associated with a high risk of readmission. Additionally, coagulopathy, chronic kidney disease and lengthier hospital stays were associated with high risk of complication or death. CONCLUSION The 30-day readmission rate following commercial treatment with the MITRACLIP device is 15%. Half of these admission were from a cardiac etiology. Heart failure, atrial arrhythmias and clip related complications round out the top 3 cardiac reasons for readmission. There was no impact of hospital size, teaching status or case volume on mortality and in hospital complication rates.

Abstract
Transradial intervention (TRI) was first introduced by Lucien Campeau in 1989 and since then has created a lasting impact in the field of interventional cardiology. Several studies have demonstrated that TRI is associated with fewer vascular site complications, offer earlier ambulation and greater post-procedural comfort. Patients presenting with ST Segment Elevation Myocardial Infarction (STEMI) have experienced survival benefit and higher quality-of-life metrics as well with TRI. While both the updated scientific statement by the American Heart Association and the 2017 European Society of Cardiology guidelines recommend a “radial first” approach there appears to be a lag in physicians adapting TRI as the preferred vascular access. We present a review focusing on identification and management of TRA related challenges and complications using a systematic algorithmic approach.

Abstract
Transcatheter aortic valve implantation (TAVI) has become the mainstream treatment for severe aortic stenosis. Despite improvement in device iteration and operator experience rigorous outcome data outside the scope of clinical trials is lacking. Nationwide readmission database 2016 and 2017 was utilized to identify the study population. International Classification of Disease,10th edition codes were used to identify TAVI admissions. Outcomes of interest were the 90-day readmission pattern and in hospital complications of the TAVI procedure. A total of 73,784 TAVI related index admissions were identified in the Nationwide Readmission Database in 2016 to 2017. Forty four percent of patients undergoing TAVI in that timeframe were discharged within 48 hours of their procedure. 16,343 patients (22.2%) were readmitted within 90 days after discharge. Major cardiac co-morbidities like heart failure were prevalent more often in the group of patients that were readmitted within 90 days. Noncardiac causes however accounted for two thirds of these readmissions. The median time to 90-day readmission was 31 days. Multivariate analysis showed that nonagenarians, patients undergoing transapical TAVI, and patients with a higher comorbidity burden were more likely to be readmitted within 90 days. In conclusion, almost half of TAVI patients in the US are discharged within 48 hours after their procedure and 20% of all TAVI patients are readmitted within 90 days. Most readmissions are due to noncardiac causes.

Abstract
Influenza is associated with significant morbidity in the United States but its influence on in-hospital outcomes in patients with AMI has not been well studied. The Nationwide Readmission Database (NRD) from 2010 to 2014 was queried using the International Classification of Diseases-Ninth edition, Clinical Modification (ICD-9-CM) codes to identify all patients ≥18 years who were admitted for AMI with and without concurrent influenza. Propensity score matching was used to adjust patients' baseline characteristics and co-morbidities. In-hospital mortality, 30-day readmission rates, in-hospital complications, and resource utilization were analyzed. We identified a total of 2,428,361 patients admitted with AMI, of whom 3,006 (0.12%) had coexisting influenza. We noted significantly higher in-hospital mortality (7.7% vs 5.6%, p <0.01) and 30-day readmission rates (15.8% vs 14.1%, p <0.01) in patients with influenza compared with those without it. After propensity matching, the differences in in-hospital mortality and 30-day readmission were no longer statistically significant between the groups. Patients with influenza had a higher incidence of acute kidney injury (30.9% vs 24.6%, p <0.01), acute respiratory failure (50.2% vs 32.2%, p <0.01), need for mechanical ventilation (13.9% vs 9.2%, p <0.01), and sepsis (10% vs 3.8%, p <0.01) in the matched cohort. Patients with influenza had longer hospital stays (8.4 days vs 6.4 days, p <0.01) and mean costs of care (26,200USD vs 23,400USD, p <0.01). In conclusion, AMI patients with concomitant influenza infection had higher in-hospital mortality, 30-day readmission, in-hospital complications, and higher resource utilization compared with those without influenza.

Abstract
BACKGROUND There is a paucity of data regarding the optimum timing of PCI in relation to TAVR. OBJECTIVE We compared the major adverse cardiovascular and cerebrovascular events (MACCE) rates among patients who underwent percutaneous coronary intervention (PCI) before transcatheter aortic valve replacement (TAVR) with those who received PCI with/after TAVR. METHODS In this multicenter study, we pooled all consecutive patients who underwent TAVR at three high volume centers. RESULTS Among 3,982 patients who underwent TAVR, 327 (8%) patients underwent PCI within 1 year before TAVR, 38 (1%) had PCI the same day as TAVR and 15 (0.5%) had PCI within 2 months after TAVR. Overall, among patients who received both PCI and TAVR (n = 380), history of previous CABG (HR:0.501; p = .001), higher BMI at TAVR (HR:0.970; p = .038), and statin therapy after TAVR (HR:0.660, p = .037) were independently associated with lower MACCE while warfarin therapy after TAVR was associated with a higher risk of MACCE (HR:1.779, p = .017). Patients who received PCI within 1 year before TAVR had similar baseline demographics, STS scores, clinical risk factors when compared to patients receiving PCI with/after TAVR. Both groups were similar in PCI (Syntax Score, ACC/AHA lesion class) and TAVR (valve types, access) related variables. There were no significant differences in terms of MACCE (log rank p = .550), all-cause mortality (log rank p = .433), strokes (log rank p = .153), and repeat PCI (log rank p = .054) in patients who underwent PCI with/after TAVR when compared to patients who received PCI before TAVR. CONCLUSION Among patients who underwent both PCI and TAVR, history of CABG, higher BMI, and statin therapy had lower, while those discharged on warfarin, had higher adverse event rates. Adverse events rates were similar regardless of timing of PCI.

Abstract
BACKGROUND Intravascular brachytherapy (VBT) is an established treatment for the management of in-stent restenosis (ISR). However, whether VBT is associated with improved patient reported outcomes unknown. METHODS We evaluated 51 consecutive patients undergoing VBT in one or more coronary arteries from January 2018 to September 2019. Data on baseline characteristics, procedural outcomes and adverse events were obtained. All patients completed the Seattle Angina Questionnaire - 7 (SAQ-7) form before and after VBT at 1 month and 6 months. RESULTS The mean age was 69 ± 9 years and 29 (57%) of patients were males. Procedural success was 94.1%. The mean summary SAQ-7 score improved significantly (53.2 ± 21 vs. 83 ± 19, p < .001) at 30-days. The median Quality of Life (QoL) component of SAQ-7 score was 31.3 (Interquartile Range [IQR]: 18.8, 62.5) and improved to 82.5 (IQR: 62.5, 100), p < .001 at 30 days and 87.5 [IQR: 75, 100), p < .001 at last follow up. Likewise, the median angina frequency component of the SQL-7 score pre-VBT was 55 (IQR: 45, 80) and improved significantly to 90 (IQR: 60, 100) at 30-days, p < .001 and 100 [IQR: 68.8, 100], p = .02 at last follow up. Lastly, the median activity component of the SAQ-7 score improved from 83.3 (IQR: 60-100) to 100 (IQR: 83, 100), p = .01 at 30-days. Thus, results were evident as early as 1 month and sustained at median follow up of 17 months. CONCLUSION VBT is associated with improvement in patient reported outcome measures at short term and long term follow up.

Abstract
Purpose To measure the inter- and intraobserver variability among operators of varying expertise in conducting CT-derived fractional flow reserve (CT FFR) measurements on-site by using structural and fluid analysis and to evaluate differences in reproducibility between two different training methods for end users. Materials and Methods This retrospective analysis of the prospectively enrolled cohort included 22 symptomatic patients who underwent both 320-detector row coronary CT angiography and catheter-derived fractional flow reserve (FFR) within 90 days. Thirteen operators of varying expertise were assigned to one of two training arms: arm 1, on-site training by a specialist in CT FFR technology; arm 2, self-training through use of written materials. After the training, all 13 operators reviewed the CT data and measured CT FFR in 24 vessels in 22 patients. Inter- and intraoperator variability and agreements between CT FFR and catheter-derived FFR measurements were evaluated. Results The overall intraclass correlation coefficient (ICC) among operators was 0.71 (95% confidence interval: 0.58, 0.83) with a mean absolute difference (± standard deviation) of 0.027 ± 0.022. The operators in arm 2 showed greater interoperator differences than those in arm 1 (0.031 ± 0.024 vs 0.023 ± 0.018; P = .024). Among operators who recalculated CT FFR, the mean CT FFR value did not significantly differ between the first and second calculations (ICC, 0.66; 95% confidence interval: 0.46, 0.87), with the medical specialists producing the lowest intraoperator variability (0.053 ± 0.060). The overall correlation coefficient between CT FFR and catheter FFR was r = 0.61, with a mean absolute difference of 0.096 ± 0.089. Conclusion Good reproducibility of CT FFR values calculated on-site on the basis of structural and fluid analysis was observed among operators of varying expertise. Face-to-face training sessions may cause less variability.© RSNA, 2019Supplemental material is available for this article.

Abstract
BACKGROUND The Society of Thoracic Surgeons (STS) scores are used to screen patients for transcatheter aortic valve replacement (TAVR). The STS scores were also used to risk stratify patients in major TAVR trials. This study evaluates the reclassification of predicted risk of mortality by the currently available online STS score calculator compared with the 2008 STS risk model in patients undergoing TAVR. METHODS AND RESULTS All patients who underwent TAVR from 2006 to 2016 were included in the study. The STS scores for all included patients were calculated by applying the 2008 STS risk model and again using the current STS online calculator. Among 1209 patients who underwent TAVR, 30-day mortality was 27 (2.2%). The overall predicted risk of mortality estimated by using the current online STS risk calculator was significantly lower than the 2008 STS risk model (6.3±4.4 vs 7.3±4.9; P<0.001). A total of 235 (19%) patients were reclassified into a lower risk category per the current STS risk model. In a multivariable logistic regression analysis, patients with persistent atrial fibrillation (odds ratio, 1.4; 95% CI, 1.0-1.9; P=0.03), chronic heart failure (odds ratio, 6.0; 95% CI, 3.8-10.1; P<0.001), and New York Heart Association class IV heart failure (odds ratio, 2.4; 95% CI, 1.3-4.4; P=0.007) were more likely to be reclassified into a lower risk category per the current STS risk model. CONCLUSIONS The current STS calculation method produces significantly lower predicted risk of mortality than the 2008 calculator, more pronounced in patients with certain comorbid conditions. These results should be considered while evaluating data from prior studies of TAVR.

Abstract
Purpose of Review Chronic total occlusion (CTO) of the coronary arteries is a significant clinical problem and has traditionally been treated by medical therapy or coronary artery bypass grafting. Recent studies have examined percutaneous coronary intervention (PCI) as an alternative option. Recent Findings This systematic review and meta-analysis compared medical therapy to PCI for treating CTOs. Summary PubMed and Embase were searched from their inception to March 2019 for studies that compared medical therapy and PCI for clinical outcomes in patients with CTOs. Quality of the included studies was assessed by Newcastle–Ottawa scale. The results were pooled by DerSimonian and Laird random- or fixed-effect models as appropriate. Heterogeneity between studies and publication bias was evaluated by I2 index and Egger’s regression, respectively. Of the 703 entries screened, 17 studies were included in the final analysis. This comprised 11,493 participants. Compared to PCI, medical therapy including randomized and observational studies was significantly associated with higher risk of all-cause mortality (risk ratio (RR) 1.99, 95% CI 1.38–2.86), cardiac mortality (RR 2.36 (1.97–2.84)), and major adverse cardiac event (RR 1.25 (1.03–1.51)). However, no difference in the rate of myocardial infarction and repeat revascularization procedures was observed between the two groups. Univariate meta-regression demonstrated multiple covariates as independent moderating factors for myocardial infarction and repeat revascularization but not cardiac death and all-cause mortality. However, when only randomized studies were included, there was no difference in overall mortality or cardiac death. In CTO, when considering randomized and observational studies, medical therapy might be associated with a higher risk of mortality and myocardial infarction compared to PCI treatment.

Abstract
BACKGROUND Frontal QRS-T angle (FQRST) has previously been correlated with mortality in patients with stable coronary artery disease, but its role as survival predictor after ST-elevation myocardial infarction (STEMI) remains unknown. METHODS We evaluated 267 consecutive patients with STEMI undergoing reperfusion or coronary artery bypass grafting. Data assessed included demographics, clinical presentation, electrocardiograms, medical therapy, and one-year mortality. RESULTS Of 267 patients, 187 (70%) were males and most (49.4%) patients were Caucasian. All-cause mortality was significantly higher among patients with the highest (101-180°) FQRST [28% vs. 15%, p = 0.02]. Patients with FQRST 1-50° had higher survival (85.6%) compared with FQRST = 51-100° (72.3%) and FQRST = 101-180° (67.9%), [log rank, p = 0.01]. Adjusting for significant variables identified during univariate analysis, FQRST (OR = 2.04 [95% CI: 1.31-13.50]) remained an independent predictor of one-year mortality. FQRST-based risk score (1-50° = 0 points, 51-100° = 2 points, 101-180° = 5 points) had excellent discriminatory ability for one-year mortality when combined with Mayo Clinic Risk Score (C statistic = 0.875 [95%CI: 0.813-0.937]. A high (>4 points) FQRST risk score was associated with greater mortality (32% vs. 19%, p = 0.02) and longer length of stay (6 vs. 2 days, p < 0.001). CONCLUSION FQRST represents a novel independent predictor of one-year mortality in patients with STEMI undergoing reperfusion. A high FQRST-based risk score was associated with greater mortality and longer length of stay and, after combining with Mayo Clinic Risk Score, improved discriminatory ability for one-year mortality.

Abstract
OBJECTIVE Neutrophil-to-lymphocyte ratio (NLR) has prognostic value in acute coronary syndromes. We investigated its utility for predicting heart failure (HF) admissions and major adverse cardiac outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS Data on clinical, laboratory, procedural, HF admissions, and major adverse cardiac events (MACEs) (all-cause mortality, recurrence of myocardial infarction requiring intervention, stroke) for 298 consecutive patients who underwent TAVR between 2012 and 2016 in our tertiary center were collected. RESULTS Analysis included 298 patients. The mean age was 83 ± 8 years, 51% were males, and 95% were Caucasians. The median Society of Thoracic Surgeons risk score was 9 (interquartile range: 6.3-11.8). Receiver-operating curve analysis identified a cutoff value of NLR of 4.0 for MACE after TAVR and sensitivity of 68% and specificity of 68% {area under the curve [AUC] = 0.65 [95% confidence interval (CI): 0.51-0.79], p = 0.03}. An NLR of 4.0 for HF hospitalizations after TAVR and sensitivity of 60% and specificity of 57% [AUC = 0.61 (95% CI: 0.53-0.69), p = 0.01]. NLR ≥4.0 before TAVR significantly predicted MACE after TAVR (68.4% vs. 31.6%, p = 0.02) and HF hospitalizations (58.3% vs. 41.7%, p = 0.03). NLR with TAVR risk score increased the predictive value for MACE after TAVR from AUC = 0.61 (95% CI: 0.50-0.72, p = 0.06) to AUC = 0.69 (95% CI: 0.57-0.80, p = 0.007). CONCLUSION NLR predicts all-cause mortality, MACE, and HF hospitalization 1 year after TAVR. NLR with TAVR risk score improved predictability for MACE. Further studies for prognostication using NLR are warranted.

Abstract
BACKGROUND Brugada syndrome is an ion channelopathy that predisposes affected subjects to ventricular tachycardia/fibrillation (VT/VF), potentially leading to sudden cardiac death (SCD). Tpeak-Tend intervals, (Tpeak-Tend)/QT ratio and Tpeak-Tend dispersion have been proposed for risk stratification, but their predictive values in Brugada syndrome have been challenged recently. METHODS A systematic review and meta-analysis was conducted to examine their values in predicting arrhythmic and mortality outcomes in Brugada Syndrome. PubMed and Embase databases were searched until 1 May 2018, identifying 29 and 57 studies. RESULTS Nine studies involving 1740 subjects (mean age 45 years old, 80% male, mean follow-up duration was 68 ± 27 months) were included. The mean Tpeak-Tend interval was 98.9 ms (95% CI: 90.5-107.2 ms) for patients with adverse events (ventricular arrhythmias or SCD) compared to 87.7 ms (95% CI: 80.5-94.9 ms) for those without such events, with a mean difference of 11.9 ms (95% CI: 3.6-20.2 ms, P = 0.005; I 2 = 86%). Higher (Tpeak-Tend)/QT ratios (mean difference = 0.019, 95% CI: 0.003-0.036, P = 0.024; I 2 = 74%) and Tpeak-Tend dispersion (mean difference = 7.8 ms, 95% CI: 2.1-13.4 ms, P = 0.007; I 2 = 80%) were observed for the event-positive group. CONCLUSION Tpeak-Tend interval, (Tpeak-Tend)/QT ratio and Tpeak-Tend dispersion were higher in high-risk than low-risk Brugada subjects, and thus offer incremental value for risk stratification.

Abstract
BACKGROUND The electrocardiographic criteria currently available for the diagnosis of left ventricular hypertrophy (LVH) are low in sensitivity. Thus, we compared the diagnostic performance of newly proposed electrocardiographic criteria to the existing criteria in a Chinese population. METHODS A total of 235 consecutive hypertensive patients, hospitalized in our department between May 2017 and April 2018, were included. They were divided into two groups based on the gold standard echocardiogram: those with (n = 116) and without LVH (n = 119). The newly proposed ECG criteria were calculated by summating the amplitude of the deepest S wave (SD ) in any single lead and the S-wave amplitude of lead V4 (SV4 ). The area under the curve was calculated and compared against the sex-specific Cornell limb lead and Sokolow-Lyon criteria. RESULTS ECG analysis of the cohort showed that the newly proposed criteria had the highest sensitivity in diagnosing LVH (male: 65.5%; female: 81%), followed by the Cornell limb lead criteria (male: 55.2%; female: 56.9%). The specificities of both sets of criteria were higher than 70%, with no significant differences between them. Receiver operator curve analysis showed an optimal cutoff of ≥2.1 mV for females (AUC: 0.832; 95% CI: 0.757-0.906) and ≥2.6 mV for males (AUC: 0.772; 95% CI: 0.687-0.856). CONCLUSION The newly proposed SD + SV4 criteria provide an improved sensitivity for the ECG diagnosis of LVH compared to existing criteria, but its routine use will require further validation in larger populations.

Abstract
BACKGROUND Permanent pacemaker implantation is the most common complication after Transcatheter aortic valve replacement (TAVR) and is associated with worse outcomes and mortality. However, its impact on quality-of-life (QoL) outcomes remains unknown. METHODS We included 383 consecutive patients undergoing TAVR from January 2012 to 2016 who completed a baseline Kansas City Cardiomyopathy Questionnaire (KCCQ-12) health survey. The clinical, laboratory, angiographic, QoL, mortality, and occurrence of poor outcomes (KCCQ-12 score < 45 or KCCQ decrease of ≥10 points) were obtained. RESULTS The mean age was 83 ± 8 years, 51% were men, and majority were Caucasians (n = 364, 95%). Permanent pacemaker (PPM) was implanted in 11.5% of patients post-TAVR. PPM patients were more likely to have prior conduction disease including RBBB (25% vs 12%, P = .02) and PQ interval >250 ms (11% vs 5%, P = .07). One-month median KCCQ-12 scores were significantly lower among PPM patients (84.7 vs 68.8, P = .04), but did not differ significantly at 1-year (86.5 vs 90.6, P = .5) post-TAVR. Occurrence of poor outcomes did not differ significantly among those with or without PPM at 1 month (11% vs 7%, P = .39) and 1 year (13% vs 9%, P = .45), respectively. However, patients with poor QoL outcomes at 1 month post-TAVR also had significantly worse mortality during follow-up in unadjusted (31.3% vs 4.5%, P < .001) and adjusted (HR = 5.30, 95% [CI: 1.85-15.22, P = .002])analyses, respectively. CONCLUSION Permanent pacemaker implantation is associated with short-term reduction in QoL without long-term implications post-TAVR. Patients with poor QoL post-TAVR also have significantly higher mortality.

OBJECTIVES The aim of this study was to determine temporal trends, in-laboratory complications, mortality, and predictors of mortality among nonagenarians undergoing percutaneous coronary intervention (PCI). BACKGROUND Nonagenarians (patients 90 years of age or older) undergoing PCI are often underrepresented in clinical trials, and their management remains challenging and controversial. METHODS All veterans undergoing PCI with data recorded in the Veterans Affairs Clinical Assessment, Reporting, and Tracking program from 2005 to 2014 were evaluated. Temporal trends in the use of PCI, occurrence of in-laboratory complications, and 30-day and 1-year mortality were assessed. Using a frailty model, predictors of 30-day and 1-year mortality in nonagenarians were evaluated. RESULTS Among all veterans undergoing PCI (n = 67,148) between 2005 and 2014, 274 (0.4%) were nonagenarians. The proportion of nonagenarians increased from 0.25% in 2008 to 0.58% in 2014. Compared with younger patients, nonagenarians had a greater risk for acute cardiogenic shock post-procedure (0.73% vs. 0.12%; p = 0.04) and no reflow (2.9% vs. 1.0%; p = 0.02). Unadjusted (10.6% vs. 1.4%; p < 0.0001) and adjusted 30-day mortality (odds ratio: 2.14; 95% confidence interval [CI]: 1.42 to 3.22) and unadjusted (16.3% vs. 4.2%; p < 0.0001) and adjusted 1-year mortality (odds ratio: 1.82; 95% CI: 1.27 to 2.62) were higher among PCI patients who were nonagenarians. The National Cardiovascular Data Registry risk score was highly predictive of both 30-day (hazard ratio: 2.29; 95% CI: 1.86 to 2.82) and 1-year (hazard ratio: 1.43; 95% CI: 1.07 to 1.90) mortality among nonagenarians. CONCLUSIONS Nonagenarians were a small but growing population with worse 30-day and 1-year mortality. The National Cardiovascular Data Registry risk score was a strong predictor of mortality in these patients.

Abstract
BACKGROUND Coronary artery disease (CAD) is the leading cause of mortality around the world. We sought to study changes in the risk profile of patients presenting with ST elevation myocardial infarction (STEMI). METHODS We retrospectively studied all patients presenting with STEMI to our center between 1995 and 2014. Patients were divided into four quartiles, 5years each. Baseline risk factors and comorbidities were recorded. Sub-analysis was done for patients with established CAD and their household incomes. RESULTS A total of 3913 patients (67.9% males) were included; 42.5% presented with anterior STEMI and 57.5% inferior STEMI. Ages were 64±12, 62±13, 61±13 and 60±13 in the four quartiles respectively. Obesity prevalence was 31, 37, 38 and 40% and diabetes mellitus prevalence was 24, 25, 24 and 31%, while hypertension was 55, 67, 70 and 77%, respectively, p<0.01 for all. Smoking prevalence was 28, 32, 42 and 46, p<0.01. When subgroup analysis was done for patients with history of CAD, prevalence of smoking, obesity, diabetes and hypertension significantly increased across the four quartiles. When patients were divided to four groups based on household income (poor, low middle, middle and high income), prevalence of diabetes, hypertension, smoking and obesity were significantly higher in patients with low income. CONCLUSION Despite better understanding of cardiovascular risk factors and more focus on preventive cardiology, patients presenting with STEMI over the past 20years are getting younger and more obese, with more prevalence of smoking, hypertension, and diabetes mellitus. This trend is greater in the lower income population.

Abstract
Objectives To characterise pregnancy course and outcomes in women with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). Methods From a combined Johns Hopkins/Dutch ARVD/C registry, we identified 26 women affected with ARVD/C (by 2010 Task Force Criteria) during 39 singleton pregnancies >13 weeks (1–4 per woman). Cardiac symptoms, treatment and episodes of sustained ventricular arrhythmias (VAs) and heart failure (HF) ≥ Class C were characterised. Obstetric outcomes were ascertained. Incidence of VA and HF were compared with rates in the non-pregnant state. Long-term disease course was compared with 117 childbearing-aged female patients with ARVD/C who had not experienced pregnancy with ARVD/C. Results Treatment during pregnancy (n=39) included β blockers (n=16), antiarrhythmics (n=6), diuretics (n=3) and implantable cardioverter defibrillators (ICDs) (n=28). In five pregnancies (13%), a single VA occurred, including two ICD-terminated events. Arrhythmias occurred disproportionately in probands without VA history (p=0.045). HF, managed on an outpatient basis, developed in two pregnancies (5%) in women with pre-existing overt biventricular or isolated right ventricular disease. All infants were live-born without major obstetric complications. Caesarean sections (n=11, 28%) had obstetric indications, except one (HF). β Blocker therapy was associated with lower birth weight (3.1±0.48 kg vs 3.7±0.57 kg; p=0.002). During follow-up children remained healthy (median 3.4 years), and mothers were without cardiac mortality or transplant. Neither VA nor HF incidence was significantly increased during pregnancy. ARVD/C course (mean 6.5±5.6 years) did not differ based on pregnancy history. Conclusions While most pregnancies in patients with ARVD/C were tolerated well, 13% were complicated by VA and 5% by HF.

Abstract
OBJECTIVES The aims of this study were to determine the clinical characteristics and outcomes of pediatric-onset arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) and to compare these with those of adult-onset ARVD/C. BACKGROUND Improved early detection and increased awareness of ARVD/C have led to a growing group of pediatric patients seeking management recommendations. Prior studies have mainly included adults with ARVD/C; however, clinical features and outcomes may differ in pediatric subjects. METHODS Among 502 subjects fulfilling task force criteria for ARVD/C, we identified 75 (15%) with pediatric-onset disease (diagnosis at <18 years of age or probands presenting symptomatically at <18 years of age). Clinical characteristics and outcomes (sustained ventricular tachycardia, cardiac transplantation, and death) were compared between pediatric and adult patients. RESULTS Pediatric patients presented at 15.3 ± 2.4 years of age. Most pediatric patients were male (55%) and ARVD/C-associated mutation carriers (80%). One-fourth of pediatric patients presented with sudden cardiac death (15%) or resuscitated sudden cardiac arrest (11%). Compared with adults, pediatric patients were disproportionately mutation carriers (p = 0.002) but not more often male (p = 0.696) or probands (p = 0.371). Pediatric patients were more likely to present with sudden cardiac death (p = 0.003), whereas adults more often presented with sustained ventricular tachycardia (p = 0.017). There were no other phenotypic differences between the groups. During 8.4 ± 7.5 years of follow-up, survival free from sustained ventricular tachycardia (p = 0.359), cardiac transplantation (p = 0.523), and death (p = 0.359) was similar between pediatric and adult patients. CONCLUSIONS Pediatric patients with ARVD/C are typically male mutation carriers presenting in adolescence. Pediatric patients disproportionately present with sudden cardiac death. However, once diagnosed, clinical characteristics and outcomes are similar between pediatric and adult patients.

Abstract
Background Exercise is associated with age‐related penetrance and arrhythmic risk in carriers of arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C)‐associated desmosomal mutations; however, its role in patients without desmosomal mutations (gene‐elusive) is uncertain. This study investigates whether exercise is (1) associated with onset of gene‐elusive ARVD/C and (2) has a differential impact in desmosomal and gene‐elusive patients. Methods and Results Eighty‐two ARVD/C patients (39 desmosomal, all probands) were interviewed about regular physical activity from age 10. Participation in endurance athletics, duration (hours/year), and intensity (MET‐Hours/year) of exercise prior to clinical presentation were compared between patients with desmosomal and gene‐elusive ARVD/C. All gene‐elusive patients were endurance athletes. Gene‐elusive patients were more likely to be endurance athletes (P<0.001) and had done significantly more intense (MET‐Hrs/year) exercise prior to presentation (P<0.001), particularly among cases presenting < age 25 (P=0.027). Family history was less prevalent among gene‐elusive patients (9% versus 40% desmosomal, P<0.001), suggesting a greater environmental influence. Gene‐elusive patients without family history did considerably more intense exercise than other ARVD/C patients (P=0.004). Gene‐elusive patients who had done the most intense (top quartile MET‐Hrs/year) exercise prior to presentation had a younger age of presentation (P=0.025), greater likelihood of meeting ARVD/C structural Task Force Criteria (100% versus 43%, P=0.02), and shorter survival free from a ventricular arrhythmia in follow‐up (P=0.002). Conclusions Gene‐elusive, non‐familial ARVD/C is associated with very high intensity exercise suggesting exercise has a disproportionate role in the pathogenesis of these cases. As exercise negatively modifies cardiac structure and promotes arrhythmias, exercise restriction is warranted.

Abstract
Background—
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a progressive cardiomyopathy. We aimed to define long-term outcome in a transatlantic cohort of 1001 individuals.
Methods and Results—
Clinical and genetic characteristics and follow-up data of ARVD/C index-patients (n=439, fulfilling of 2010 criteria in all) and family members (n=562) were assessed. Mutations were identified in 276 index-patients (63%). Index-patients presented predominantly with sustained ventricular arrhythmias (268; 61%). During a median follow-up of 7 years, 301 of the 416 index-patients presenting alive (72%) experienced sustained ventricular arrhythmias. Sudden cardiac death during follow-up occurred more frequently among index-patients without an implantable cardioverter-defibrillator (10/63, 16% versus 2/335, 0.6%). Overall, cardiac mortality and the need for cardiac transplantation were low (6% and 4%, respectively). Clinical characteristics and outcomes were similar in index-patients with and without mutations, as well as in those with familial and nonfamilial ARVD/C. ARVD/C was diagnosed in 207 family members (37%). Symptoms at first evaluation correlated with disease expression. Family members with mutations were more likely to meet Task Force Criteria for ARVD/C (40% versus 18%), experience sustained ventricular arrhythmias (11% versus 1%), and die from a cardiac cause (2% versus 0%) than family members without mutations.
Conclusions—
Long-term outcome was favorable in diagnosed and treated ARVD/C index-patients and family members. Outcome in index-patients was modulated by implantable cardioverter-defibrillator implantation, but not by mutation status and familial background of disease. One third of family members developed ARVD/C. Outcome in family members was determined by symptoms at first evaluation and mutations.

Abstract
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is rare cardiomyopathy associated with life-threatening arrhythmias and increased risk of sudden cardiac death. In addition to mutations in desmosomal genes, environmental factors such as exercise have been implicated in the pathogenesis of the disease. Recent studies have shown that exercise may be associated with adverse outcomes in ARVD/C patients. Based on current evidence, ARVD/C patients are recommended to limit exercise irrespective of their mutation status. In addition, some studies have suggested the presence of an entirely acquired form of the disease caused by exercise that has been dubbed exercise-induced ARVD/C.

Abstract
BACKGROUND Several inflammation biomarkers have been implicated in the pathogenesis and prognosis of acute coronary syndromes. However, the prognostic role of the neutrophil-lymphocyte white cell interactive response to myocardial injury in predicting short- and long-term mortality after ST elevation myocardial infarction (STEMI) remains poorly defined. METHODS We evaluated 250 consecutive STEMI patients presenting acutely for revascularization to our tertiary care center over 1 year. Patients with acute sepsis, trauma, recent surgery, autoimmune diseases, or underlying malignancy were excluded. Data gathered included demographics, clinical presentation, leukocyte markers, electrocardiograms, evaluations, therapy,major adverse cardiac events, and all-cause mortality. RESULTS Mean age was 62 ± 15 years, 70.4% of subjects were males while majority (49.4%) were Caucasians. Mean duration of follow-up was 571 ± 291 days (median 730 days). Univariate analysis of several inflammatory biomarkers including C-reactive protein, revealed white cell count (OR = 1.09, p < 0.001) and neutrophil to lymphocyte ratio (NLR) (OR = 1.05, p = 0.011) as predictors of short- and long-term mortality; but not mean neutrophil count (OR = 1.04, p = 0.055) or lymphocyte count alone (OR = 0.96, p = 0.551). Multivariate analysis using backward stepwise regression revealed NLR (OR = 2.64, p = 0.026), female gender (OR = 5.35, p < 0.001), cerebrovascular accident history (OR = 3.36, p = 0.023), low glomerular filtration rate (OR = 0.98, p = 0.012) and cardiac arrest on admission (OR = 17.43, p < 0.001) as robust independent predictors of long-term mortality. NLR was divided into two sub-groups based on an optimal cut off value of 7.4. This provided the best discriminatory cut off point for predicting adverse mortality outcome. Both short-term (≤ 30 days) and long-term (≤ 2 years) mortality were predicted with Kaplan-Meier survival curve separation best stratified by a NLR cut off value of 7.4. CONCLUSIONS NLR based on an optimal cut off value of 7.4, was an excellent predictor of short- and long-term survival in patients with revascularized STEMI and warrants larger scale multi-center prospective evaluation, as a prognostic indicator. NLR offers improved prognostic capacity when combined with conventional clinical scoring systems, such as the Thrombolysis In Myocardial Infarction risk score.

Abstract
The bacterium Alcaligenes xylosoxidans is known to cause several nosocomial infections; however, it rarely causes endocarditis, which has a very high mortality rate. Early isolation of the infection source and prompt identification of the patient's antibiotic sensitivities are paramount if the infection is to be treated adequately. We present what is apparently only the second documented case of the successful eradication of bioprosthetic valve endocarditis that was caused by pacemaker lead infection with Alcaligenes xylosoxidans. A 62-year-old woman with multiple comorbidities presented with endocarditis of a recently placed bioprosthetic aortic valve. The infection was secondary to pacemaker lead infection. She underwent antibiotic therapy, but an unusual pattern of antibiotic resistance developed. Despite initially adequate therapy, the infection recurred because of virulence induced by antibiotic resistance. Emergent, high-risk surgical treatment involved excising the infected valve and removing the source of the infection (the pacemaker leads). The patient eventually recovered after prolonged antibiotic therapy and close vigilance for recurrent infection. In addition to the patient's case, we discuss the features of this bacteremia and the challenges in its diagnosis.

Abstract
Caffeine has been suggested as a possible risk factor for breast cancer, potentially through its effect of facilitating the development of benign breast disease. However, coffee and tea also contain polyphenols, which exhibit anticarcinogenic properties. A hospital-based, case-control study was conducted to evaluate the role of coffee, decaffeinated coffee, and black tea in breast cancer etiology. Study participants included 1932 cases with primary, incident breast cancer and 1895 hospital controls with nonneoplastic conditions. All participants completed a comprehensive epidemiological questionnaire. Among premenopausal women, consumption of regular coffee was associated with linear declines in breast cancer risk (P for trend = 0.03); consumers of >or=4 cups/d experienced a 40% risk reduction (odds ratio = 0.62, 95% CI 0.39-0.98). No clear associations between intake of black tea or decaffeinated coffee and breast cancer risk were noted among premenopausal women, although black tea was associated with a protective effect unique to a subsample of cases with lobular histology. Among postmenopausal women, breast cancer risk was not associated with consumption of coffee, tea, or decaffeinated coffee. Results among postmenopausal women did not differ by histologic subtype. Our findings support a protective effect of coffee intake on premenopausal, but not postmenopausal breast cancer risk. Further studies are warranted to confirm these findings.
