Abstract
The Old-Age Heart Abstract. Knowledge of cardiovascular changes in old age and their therapeutic options is important. Old age can lead to hypertrophy of the left ventricle, diastolic dysfunction, heart valve changes and pulmonary hypertension. Patients often develop arterial hypertension. Valvular changes are common in people over 100 years of age (aortic stenosis and mitral insufficiency). The risk of coronary heart disease is 35 % for men and 24 % for women. In old age, sinus node dysfunction and atrial fibrillation are common. 25 % of all strokes are cardiac embolisms in atrial fibrillation. Cardiac interventions in the elderly are increasingly frequent and include coronary catheter revascularization or valve interventions (percutaneous aortic valve replacement or MitraClip). Optimal therapy in old age includes not only cardiovascular interventions also include drugs and a lifestyle modification and mainly serves to improve the quality of life.

Abstract
Aims To analyse reasons, timing and predictors of hospital readmissions after transcatheter aortic valve implantation (TAVI). Methods and results Patients included in the Bern TAVI Registry between August 2007 and June 2014 were analysed. Fine and Gray competing risk regression was used to identify factors predictive of hospital readmission within 1 year after TAVI with bootstrap analysis for internal validation. Of 868 patients alive at discharge, 221 (25.4%) were readmitted within 1 year. Compared with patients not requiring readmission, those with at least one readmission more frequently were male and more often had atrial fibrillation and higher creatinine values (P < 0.05 for all cases). For overall 308 readmissions, cardiovascular causes accounted for 46.1% with heart failure as the most frequent indication; non-cardiovascular readmissions occurred for surgery (11.7%), gastrointestinal disorders (9.7%), malignancy (4.9%), respiratory diseases (4.6%) and chronic kidney failure (2.6%). Male gender (subhazard ratio, SHR, 1.33, 95% confidence intervals, CI, 1.02-1.73, P = 0.035) and stage 3 kidney injury (SHR 2.04, 95% CI 1.12-3.71, P = 0.021) were found independent risk factors for any hospital readmission, whereas previous myocardial infarction (SHR 1.88, 95% CI 1.22-2.90, P = 0.004) and in-hospital life-threatening bleeding (SHR 2.18, 95%CI 1.24-3.85, P = 0.007) were associated with cardiovascular readmissions. The event rate for mortality was significantly increased after readmissions for any cause (RR 4.29, 95% CI 2.86-6.42, P < 0.001). Conclusion Hospital readmission was observed in one out of four patients during the first year after TAVI and was associated with a significant increase in mortality.

Abstract
SummaryDrug-drug interaction between statins metabolised by cytochrome P450 3A4 and clopidogrel have been claimed to attenuate the inhibitory effect of clopidogrel. However, published data regarding this drug-drug interaction are controversial. We aimed to determine the effect of fluvastatin and atorvastatin on the inhibitory effect of dual anti-platelet therapy with acetylsalicylic acid (ASA) and clopidogrel. One hundred one patients with symptomatic stable coronary artery disease undergoing percutaneous coronary intervention and drug-eluting stent implantation were enrolled in this prospective randomised study. After an interval of two weeks under dual antiplatelet therapy with ASA and clopidogrel, without any lipid-lowering drug, 87 patients were randomised to receive a treatment with either fluvastatin 80 mg daily or atorvastatin 40 mg daily in addition to the dual antiplatelet therapy for one month. Platelet aggregation was assessed using light transmission aggregometry and whole blood impedance platelet aggregometry prior to randomisation and after one month of receiving assigned statin and dual antiplatelet treatment. Platelet function assessment after one month of statin and dual antiplatelet therapy did not show a significant change in platelet aggregation from 1st to 2nd assessment for either statin group. There was also no difference between atorvastatin and fluvastatin treatment arms. In conclusion, neither atorvastatin 40 mg daily nor fluvastatin 80 mg daily administered in combination with standard dual antiplatelet therapy following coronary drug-eluting stent implantation significantly interfere with the antiaggregatory effect of ASA and clopidogrel.

Abstract
AIMS The ADVANCE study was designed to evaluate the safety and effectiveness of transcatheter aortic valve implantation (TAVI) with a self-expanding bioprosthesis in real-world patients with symptomatic, severe aortic stenosis at high surgical risk for valve replacement. METHODS AND RESULTS Study participants were enrolled from 44 experienced centres in 12 countries. Patient eligibility, treatment approach, and choice of anaesthesia were determined by the local Heart Team. The study was 100% monitored, and adverse events were adjudicated by an independent clinical events committee using Valve Academic Research Consortium (VARC-1) criteria. There were 1015 patients enrolled with 996 attempted TAVI procedures. Mean age was 81 years, and mean logistic EuroSCORE was 19.3 ± 12.3%. Five-year follow-up was available on 465 (46.7%) patients. At 5 years, the rate of all-cause mortality was 50.7% (95% confidence interval: 46.7%, 54.5%), and the rate of major stroke was 5.4%. Haemodynamic measures remained consistent for paired patients with a mean aortic valve gradient of 8.8 ± 4.4 mmHg (n = 198) and an effective orifice area of 1.7 ± 0.4 cm2 (n = 123). Aortic regurgitation (AR) decreased over time and among paired patients dropped from 12.8% to 8.0% moderate AR at 5 years (n = 125). Of the 860 patients with echocardiographic data or a reintervention after 30 days, there were 22 (2.6%) patients meeting the VARC-2 criteria for valve dysfunction and 10 (1.2%) patients with a reintervention >30 days. CONCLUSION Five-year results in real-world, elderly, high-risk patients undergoing TAVI with a self-expanding bioprosthesis provided evidence for continued valve durability with low rates of reinterventions and haemodynamic valve dysfunction.

Abstract
BACKGROUND Extensive evidence relating to transcatheter aortic valve replacement (TAVR) has accumulated in recent years, but mid-term outcomes are less reported. We investigated 996 patients after implantation of the CoreValve prosthesis for severe aortic stenosis in a real-world setting. OBJECTIVE To report clinical and echocardiographic 3-year results from the ADVANCE study. METHODS ADVANCE is a prospective, multicenter, fully monitored, nonrandomized clinical study. This analysis assessed valve-related events, predictors of early and mid-term mortality after TAVR, and systolic and diastolic prosthesis performance over 3 years. RESULTS Three years after TAVR, the rate of major adverse cardiac/cerebrovascular events was 38.5%. All-cause mortality was 33.7%; cardiovascular mortality, 22.3%; VARC-1 stroke, 6.5%; and New York Heart Association class III/IV, 19.5%. Mean effective orifice area was consistently 1.7 cm2 from discharge to 3 years, and average mean aortic valve gradient remained ≤10 mmHg. At 3 years, 12.6% of patients had moderate and none had severe paravalvular regurgitation. Multivariable analysis identified Society of Thoracic Surgeons (STS) score, device migration, prior atrial fibrillation, and major vascular complication as predictors of early mortality. Predictors of mid-term mortality included male gender, STS score, history of chronic obstructive pulmonary disease, history of cancer, stroke, life-threatening/disabling or major bleeding, and valve deterioration. CONCLUSIONS Our 3-year data demonstrate significant hemodynamic benefits and durable symptom relief after CoreValve prosthesis implantation. Postprocedural patient management should be carefully considered, since postprocedural valve-related events were identified as independent predictors of mid-term mortality.

Abstract
AIMS We aimed to demonstrate the feasibility and investigate the safety of a novel, self-expanding trans-catheter heart valve in a selected patient population with severe aortic stenosis. METHODS AND RESULTS Between January and September 2013, a total of 21 patients with symptomatic severe aortic stenosis were eligible for transcatheter aortic valve implantation (TAVI) with the self-expanding NVT Allegra bioprosthesis (New Valve Technology, Hechingen, Germany) at two cardiovascular centres. Patients were elderly (age 83.8±4 years), predominantly female (95.2%), and all were considered to be at prohibitive risk for surgical aortic valve replacement (logistic EuroSCORE 30.4±11%). Procedural and device success was achieved in 95.2% and 85.7%, respectively. Echocardiographic assessment at discharge showed favourable haemodynamic results with a reduction of the mean transvalvular aortic gradient from 48.0±21 mmHg to 8.9±3 mmHg. In the majority of patients (90.5%), none or trace aortic regurgitation was recorded. Permanent pacemaker implantation was required in 23.8% of patients within the first 30 days of follow-up. Apart from one procedural death, no other serious adverse events were observed during the periprocedural period. TAVI with the NVT Allegra system was highly effective in alleviating symptoms and reducing NYHA functional class at 30-day follow-up. CONCLUSIONS The first-in-human experience with the NVT Allegra transcatheter heart valve prosthesis was associated with a high rate of procedural success. Furthermore, the NVT Allegra bioprosthesis was able to achieve favourable haemodynamic results and effectively alleviate symptoms at 30-day follow-up. The larger, multicentre NAUTILUS study will provide further information on the safety and efficacy of this novel, second-generation transcatheter aortic bioprosthesis.

Abstract
AIMS Data on procedural and clinical outcomes after transcatheter aortic valve implantation (TAVI) with the new-generation self-expanding Medtronic Evolut R prosthesis in comparison with its predecessor, the Medtronic CoreValve, are scarce. The aim of this study was to assess the safety and efficacy of the Evolut R device compared with the former-generation CoreValve. METHODS AND RESULTS In a nationwide, prospective, multicentre cohort study, outcomes of consecutive transfemoral TAVI patients treated with the new-generation Medtronic Evolut R (September 2014 - February 2016) and the Medtronic CoreValve (February 2011 - February 2016) were investigated. Events were reported according to VARC-2 and adjudicated by a clinical events committee. During the study period, 317 and 678 consecutive patients underwent TAVI with the Evolut R and the CoreValve bioprosthesis, respectively. Baseline clinical characteristics between the groups were comparable, although Evolut R patients were lower risk according to the STS score (4.8±3.4% vs. 6.9±5.0%, p<0.001) and logistic EuroSCORE (17.3±13% vs. 20.1±13%, p=0.009). Implantation of the Evolut R was associated with a lower use of predilatation (48.1% vs. 72.4%, p<0.001), a shorter procedure time (67.9±36 min vs. 76.7±42 min, p=0.002), and less contrast dye use during the procedure (155.2±98 ml vs. 208.0±117 ml, p<0.001). Post-procedural mean gradient was comparable (7.4±4.7 mmHg vs. 7.5±5.0 mmHg), as were the 30-day rates of moderate to severe aortic regurgitation (8.5% vs. 10.5%), major vascular (9.8% vs. 10.3%) and life-threatening bleeding complications (5.4% vs. 5.3%), disabling stroke (1.9% vs. 1.6%), all-cause mortality (3.2% vs. 3.4%) as well as permanent pacemaker implantation (22.1% vs. 23.4%). CONCLUSIONS Thirty-day clinical outcomes were favourable and comparable between the Evolut R and the CoreValve bioprosthesis.

Abstract
Transcatheter aortic valve implantation (TAVI) has evolved into a safe and effective procedure to treat symptomatic patients with severe aortic stenosis (AS), with predictable and reproducible results. Rates of important complications such as vascular complications, strokes and paravalvular leaks are lower than ever, because of improved patient selection, systematic use of multidector computer tomography, increasing operator experience and device iteration. Accumulating data suggest that transfemoral TAVI with newer generation transcatheter heart valves and delivery systems is superior to conventional surgical aortic valve replacement among intermediate- and high-risk patients with severe symptomatic AS with regard to all-cause mortality and stroke. One can anticipate that by 2020, the majority of patients with severe symptomatic AS will undergo TAVI as first line therapy, regardless of surgical risk.

Abstract
Background The safety and effectiveness of the fully repositionable LOTUS valve system as compared with the balloon‐expandable Edwards SAPIEN 3 prosthesis for the treatment of aortic stenosis has not been evaluated to date. Methods and Results All patients undergoing transcatheter aortic valve implantation with the Edwards SAPIEN 3 or the LOTUS valve system were included into the Swiss Transcatheter Aortic Valve Implantation Registry. An adjusted analysis was performed to compare the early clinical safety outcome according to the Valve Academic Research Consortium‐2 definition. Between February 2014 and September 2015, 140 and 815 patients were treated with the LOTUS and the Edwards SAPIEN 3 valve, respectively. There was no difference in crude and adjusted analyses of the early safety outcome between patients treated with LOTUS (14.3%) and those treated with Edwards SAPIEN 3 (14.6%) (crude hazard ratio, 0.97; 95% CI, 0.61–1.56 [P=0.915]; adjusted hazard ratio, 1.03; 95% CI, 0.64–1.67 [P=0.909]). More than mild aortic regurgitation was <2% for both devices. A total of 34.3% of patients treated with LOTUS and 14.1% of patients treated with Edwards SAPIEN 3 required a permanent pacemaker (HR, 2.76; 95% CI, 1.97–3.87 [P<0.001]). Conclusions The repositionable LOTUS valve system and the balloon‐expandable Edwards SAPIEN 3 prosthesis appeared comparable in regard to the Valve Academic Research Consortium‐2 early safety outcome, and the rates of more than mild aortic regurgitation were exceedingly low for both devices. The need for new permanent pacemaker implantation was more frequent among patients treated with the LOTUS valve.

Abstract
BACKGROUND This study aimed to assess the evolution of cognitive function after transcatheter aortic valve implantation (TAVI). Previous smaller studies reported conflicting results on the evolution of cognitive function after TAVI. METHODS AND RESULTS In this prospective cohort, cognitive function was measured in 229 patients ≥70 years using the Mini Mental State Examination before and 6 months after TAVI. Cognitive deterioration or improvement was defined as change of ≥3 points decrease or increase in the Mini Mental State Examination score between baseline and follow-up. Cognitive deterioration was found in 29 patients (12.7%). Predictive analysis using logistic regression did not identify any statistically significant predictor of cognitive deterioration. A review of individual medical records in 8 patients with a major Mini Mental State Examination score decrease of ≥5 points revealed specific causes in 6 cases (postinterventional delirium in 2; postinterventional stroke, progressive renal failure, progressive heart failure, or combination of preexisting cerebrovascular disease and mild cognitive impairment in 1 each). Among 48 patients with impaired baseline cognition (Mini Mental State Examination score <26 points), 18 patients (37.5%) cognitively improved. The preinterventional aortic valve area was lower in patients who cognitively improved (median aortic valve area 0.60 cm2) as compared with patients who did not improve (median aortic valve area 0.70 cm2; P=0.01). CONCLUSIONS This is the first study providing evidence that TAVI results in cognitive improvement among patients who had impaired preprocedural cognitive function, possibly related to hemodynamic improvement in patients with severe aortic stenosis. Our results confirm that some patients experience cognitive deterioration after TAVI.

Abstract
BACKGROUND New generation transcatheter heart valves (THV) may improve clinical outcomes of transcatheter aortic valve implantation. METHODS AND RESULTS In a nationwide, prospective, multicenter cohort study (Swiss Transcatheter Aortic Valve Implantation Registry, NCT01368250), outcomes of consecutive transfemoral transcatheter aortic valve implantation patients treated with the Sapien 3 THV (S3) versus the Sapien XT THV (XT) were investigated. An overall of 153 consecutive S3 patients were compared with 445 consecutive XT patients. Postprocedural mean transprosthetic gradient (6.5±3.0 versus 7.8±6.3 mm Hg, P=0.17) did not differ between S3 and XT patients, respectively. The rate of more than mild paravalvular regurgitation (1.3% versus 5.3%, P=0.04) and of vascular (5.3% versus 16.9%, P<0.01) complications were significantly lower in S3 patients. A higher rate of new permanent pacemaker implantations was observed in patients receiving the S3 valve (17.0% versus 11.0%, P=0.01). There were no significant differences for disabling stroke (S3 1.3% versus XT 3.1%, P=0.29) and all-cause mortality (S3 3.3% versus XT 4.5%, P=0.27). CONCLUSIONS The use of the new generation S3 balloon-expandable THV reduced the risk of more than mild paravalvular regurgitation and vascular complications but was associated with an increased permanent pacemaker rate compared with the XT. Transcatheter aortic valve implantation using the newest generation balloon-expandable THV is associated with a low risk of stroke and favorable clinical outcomes.

Abstract
Transcatheter aortic valve implantation (TAVI) has become the standard of care for many patients with symptomatic severe aortic stenosis who are at increased risk of morbidity and mortality during surgical aortic valve replacement. However, there is still no general consensus regarding the use of general anesthesia (GA) versus local anesthesia with sedation (non-GA) during the TAVI procedure. Using propensity score-matching analysis, we analyzed the characteristics and outcomes of patients who underwent TAVI with either GA (n = 245) or non-GA (n = 245) in the fully monitored, international, CoreValve ADVANCE Study. No statistically significant differences existed between the non-GA and GA groups in all-cause mortality (25.4% vs 23.9%, p = 0.78), cardiovascular mortality (16.4% vs 16.6%, p = 0.92), or stroke (5.2% vs 6.9%, p = 0.57) through 2-year follow-up. Major vascular complications were more common in the non-GA group. Total hospital stay was similar between the 2 groups. Conversion from non-GA to GA occurred in 13 patients (5.3%) because of procedural complications in 9 patients and discomfort or restlessness in 4 patients. Most procedural complications were related to valve positioning or vascular issues. Two of the 13 converted patients died during the procedure. Both GA and non-GA are widely used in real-world TAVI practice, and the decision appears to be guided by only a few patient-related factors and dominated by local and national practice. The outcomes of both anesthesia modes are equally good. When conversion from non-GA did occur, the complication requiring GA affected outcomes.

Abstract
BACKGROUND Pulmonary hypertension (PH) frequently coexists with severe aortic stenosis, and PH severity has been shown to predict outcomes after transcatheter aortic valve implantation (TAVI). The effect of PH hemodynamic presentation on clinical outcomes after TAVI is unknown. METHODS AND RESULTS Of 606 consecutive patients undergoing TAVI, 433 (71.4%) patients with severe aortic stenosis and a preprocedural right heart catheterization were assessed. Patients were dichotomized according to whether PH was present (mean pulmonary artery pressure, ≥25 mm Hg; n=325) or not (n=108). Patients with PH were further dichotomized by left ventricular end-diastolic pressure into postcapillary (left ventricular end-diastolic pressure, >15 mm Hg; n=269) and precapillary groups (left ventricular end-diastolic pressure, ≤15 mm Hg; n=56). Finally, patients with postcapillary PH were divided into isolated (n=220) and combined (n=49) subgroups according to whether the diastolic pressure difference (diastolic pulmonary artery pressure-left ventricular end-diastolic pressure) was normal (<7 mm Hg) or elevated (≥7 mm Hg). Primary end point was mortality at 1 year. PH was present in 325 of 433 (75%) patients and was predominantly postcapillary (n=269/325; 82%). Compared with baseline, systolic pulmonary artery pressure immediately improved after TAVI in patients with postcapillary combined (57.8±14.1 versus 50.4±17.3 mm Hg; P=0.015) but not in those with precapillary (49.0±12.6 versus 51.6±14.3; P=0.36). When compared with no PH, a higher 1-year mortality rate was observed in both precapillary (hazard ratio, 2.30; 95% confidence interval, 1.02-5.22; P=0.046) and combined (hazard ratio, 3.15; 95% confidence interval, 1.43-6.93; P=0.004) but not isolated PH patients (P=0.11). After adjustment, combined PH remained a strong predictor of 1-year mortality after TAVI (hazard ratio, 3.28; P=0.005). CONCLUSIONS Invasive stratification of PH according to hemodynamic presentation predicts acute response to treatment and 1-year mortality after TAVI.

Abstract
Aortic stenosis is the most common valvular heart disease in Western industrial countries (including Switzerland) with a prevalence of about 5% in the population aged 75 and over. If left untreated, symptomatic patients have a rate of death of more than 50% within 2 years. As a result of age and elevated surgical risk, an important proportion of elderly patients are not referred to surgery. Thus, the introduction of transcatheter aortic valve implantation (TAVI) in 2002 has initiated a paradigm shift in the treatment of patients with symptomatic, severe aortic stenosis. The early technical and procedural success of this minimal invasive treatment in high-risk patients has promoted further innovation and development of transcatheter heart valve (THV) systems during the last 13 years. Downsizing of the delivery catheters along with technical improvements aiming to reduce postprocedural paravalvular regurgitation have resulted in a significant reduction in mortality. As a consequence, TAVI is nowadays established as safe and effective treatment for selected inoperable and high-risk patients. Ongoing studies are investigating the outcome of intermediate risk patients allocated to either surgical aortic valve replacement (SAVR) or TAVI. Despite these advancements, some specific areas of concern still require attention and need further investigations including conduction disturbances, valve degeneration and antithrombotic management. Although the off-label use of TAVI devices in the mitral, tricuspid or pulmonary position has recently developed, important limitations still apply and careful patient selection remains crucial. This review aims to summarise the available clinical evidence of transcatheter aortic valve treatment during the last 13 years and to provide a glimpse of future technologies.
