Limited evidence exists concerning the prognostic impact of baseline left ventricular ejection fraction (LVEF) on outcomes among women undergoing transcatheter aortic valve implantation (TAVI), which we aimed to investigate in the present analysis. Patients from the Women's International Transcatheter Aortic Valve Implantation (WIN-TAVI) registry were categorized according to baseline LVEF into 3 groups: reduced (LVEF ≤40%), mildly reduced (LVEF between 41% and 49%), and preserved (LVEF ≥50%) LVEF. The primary (Valve Academic Research Consortium 2 [VARC-2]) efficacy point was defined as a composite of mortality, stroke, myocardial infarction, hospitalization for valve-related symptoms or heart failure, or valve-related dysfunction at 1 year. The primary (VARC-2) safety end point included all-cause mortality, stroke, major vascular complication, life-threatening bleeding, stage 2 to 3 acute kidney injury, coronary artery obstruction requiring intervention, or valve-related dysfunction requiring repeated procedures. A Cox regression model was performed using the preserved LVEF group as the reference. Among the 944 patients included, 764 (80.9%) exhibited preserved, 80 (8.5%) had mildly reduced, and 100 (10.6%) had reduced LVEF. The 1-year incidence of VARC-2 efficacy end point was numerically higher in patients with reduced LVEF, albeit not resulting in a significant risk difference. Notably, reduced LVEF was associated with a higher risk of the 1-year VARC-2 safety end point, still significant after adjustment (28.0% vs 19.6%, Hazard Ratio 1.78, 95% Confidence Interval 1.12- 2.82, p = 0.014). These differences were primarily driven by trends toward increased rates of all-cause mortality, cardiovascular mortality, and major vascular complications. Clinical outcomes were similar between patients with mildly reduced and preserved LVEF. In conclusion, when performed in women with reduced LVEF, TAVI was associated with a worse (VARC-2) safety profile at 1-year follow-up. In contrast, patients with mildly reduced LVEF appeared to align more closely with outcomes observed in the preserved LVEF group than with the reduced LVEF group., Competing Interests: Declaration of competing interest Dr. Bay is supported by a grant from the German Heart Foundation, grant no.

Early menopause is associated with an increased risk of cardiovascular diseases, including aortic stenosis (AS). We sought to investigate the prevalence and impact of early menopause on clinical outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) for severe symptomatic AS. Women's International TAVI is a multinational, prospective, observational registry of women who underwent TAVI for severe symptomatic AS (n = 1,019). Patients were divided into 2 groups based on age of menopause: early menopause (age ≤45 years) and regular menopause (age >45 years). The primary outcome of interest was Valve Academic Research Consortium 2 efficacy end point, a composite of mortality, stroke, myocardial infarction, hospitalization for valve-related symptoms, or heart failure or valve-related dysfunction at 1-year follow-up. Of 732 patients with available data on menopause age, 173 (23.6%) were classified as having early menopause. These patients presented for TAVI at a younger age (81.6 ± 6.9 vs 82.7 ± 5.9, p = 0.05) and had a significantly lower Society of Thoracic Surgeons score (6.6 ± 4.8 vs 8.2 ± 7.1, p = 0.03) than those with regular menopause. However, the total valve calcium volume was smaller among patients with early versus regular menopause (731.8 ± 850.9 mm 3 vs 807.6 ± 633.8 mm 3 , p = 0.002). Other co-morbidities were similar between the 2 groups. At 1-year follow-up, there were no significant differences in clinical outcomes between patients with early versus regular menopause (hazard ratio 1.00, 95% confidence interval 0.61 to 1.63, p = 1.00). In conclusion, despite presenting for TAVI at a younger age, patients with early menopause had a similar risk of adverse events as patients with regular menopause at 1 year after TAVI., Competing Interests: Disclosures Dr. Chieffo received consultancy fees from Abiomed, Biosensor, Edwards and Shockwave Medical and payments for lecturs from Boston Scientific and Abbot Vascular.

Scarce data exist on mitral valve (MV) infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). This multicenter study included a total of 579 patients with a diagnosis of definite IE after TAVI from the IE after TAVI International Registry and aimed to evaluate the incidence, characteristics, management, and outcomes of MV-IE after TAVI. A total of 86 patients (14.9%) had MV-IE. These patients were compared with 284 patients (49.1%) with involvement of the transcatheter heart valve (THV) only. Two factors were found to be associated with MV-IE: the use of self-expanding valves (adjusted odds ratio 2.49, 95% confidence interval [CI] 1.23 to 5.07, p = 0.012), and the presence of an aortic regurgitation ≥2 at discharge (adjusted odds ratio 3.33; 95% CI 1.43 to 7.73, p <0.01). There were no differences in IE timing and causative microorganisms between groups, but surgical management was significantly lower in patients with MV-IE (6.0%, vs 21.6% in patients with THV-IE, p = 0.001). All-cause mortality rates at 2-year follow-up were high and similar between patients with MV-IE (51.4%, 95% CI 39.8 to 64.1) and patients with THV-IE (51.5%, 95% CI 45.4 to 58.0) (log-rank p = 0.295). The factors independently associated with increased mortality risk in patients with MV-IE were the occurrence of heart failure (adjusted p <0.001) and septic shock (adjusted p <0.01) during the index hospitalization. One of 6 IE episodes after TAVI is localized on the MV. The implantation of a self-expanding THV and the presence of an aortic regurgitation ≥2 at discharge were associated with MV-IE. Patients with MV-IE were rarely operated on and had a poor prognosis at 2-year follow-up., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Although most patients with small aortic annulus are women, there is paucity of data on the prognostic impact of small aortic prosthesis in women who underwent transcatheter aortic valve implantation (TAVI). Therefore, we aimed to evaluate the impact of small valve size on 1-year clinical outcomes after TAVI in women. The Women's INternational Transcatheter Aortic Valve Implantation is an all-women registry evaluating patients with severe aortic stenosis who underwent TAVI. Based on the size of the aortic bioprosthesis implanted, women were stratified into small (≤23 mm) and nonsmall (>23 mm) valve. The primary efficacy endpoint was the Valve Academic Research Consortium-2 composite of all-cause death, stroke, myocardial infarction, hospitalization for valve-related symptoms or heart failure or valve-related dysfunction at 1-year follow-up. Of 934 women who underwent TAVI, 388 (41.5%) received a small valve. Women with a small valve size had a lower body mass index, lower surgical risk scores, were less likely to suffer from atrial fibrillation, less often required postdilation and had a lower rate of residual aortic regurgitation grade ≥2. The occurrence of the Valve Academic Research Consortium-2 efficacy endpoint was similar between women treated with small and nonsmall valve (16.0% vs 16.3%, p = 0.881; adjusted hazard ratio 1.34, 95% confidence interval 0.90 to 2.00). Likewise, there were no significant differences in the occurrence of other secondary endpoints after multivariable adjustment. In conclusion, women with severe aortic stenosis who underwent TAVI with the implantation of a small valve bioprosthesis had similar 1-year outcomes as those receiving a nonsmall bioprosthesis., (Copyright © 2022 Elsevier Inc.

We sought to analyze outcomes of women receiving balloon-expandable valves (BEV) or self-expanding valves (SEV) in contemporary transcatheter aortic valve implantation (TAVI). WIN TAVI (Women's INternational Transcatheter Aortic Valve Implantation) is the first all-female TAVI registry to study the safety and performance of TAVI in women. We compared women treated with BEV (n = 408, 46.9%) versus those treated with SEV (n = 461, 53.1%). The primary efficacy end point was the Valve Academic Research Consortium-2 (VARC-2) composite of 1-year all-cause death, stroke, myocardial infarction, hospitalization for valve-related symptoms or heart failure or valve-related dysfunction. Women receiving SEV had higher surgical risk scores, higher rate of previous stroke and pulmonary hypertension whereas women receiving BEV were more frequently denied surgical valve replacement due to frailty. BEV patients were less likely to require post-dilation and had significantly lower rates of residual aortic regurgitation grade ≥2 (9.8% vs 4.7%, p = 0.007). At 1 year, the crude incidence and adjusted risk of the primary VARC-2 efficacy end point was similar between groups (17.1% with SEV and 14.3% with BEV, p = 0.25; hazards ratio 1.09, 95% confidence interval 0.68 to 1.75). Conversely the crude rate and adjusted risk of new pacemaker implantation was higher with SEV than BEV (15% vs 8.6%, p = 0.001; hazards ratio 1.97, 95% confidence interval 1.13 to 3.43). A subanalysis on new generation valves showed no difference in the need for pacemaker implantation between the 2 devices (10.1% vs 8.0%, p = 0.56). In conclusion, in contemporary TAVI, SEV are used more frequently in women with greater co-morbidities. While there were no differences in unadjusted and adjusted risk of 1-year primary efficacy end point between the valve types, there was a greater need for permanent pacemakers after SEV implantation., (Copyright © 2019 Elsevier Inc.

Results from randomized trials evaluating thrombus aspiration (TA) in patients with ST-elevation myocardial infarction (STEMI) are conflicting. We assessed 1-year survival in STEMI patients participating in the French Registry of Acute ST-Elevation and non-ST-Elevation Myocardial Infarction (FAST-MI) 2010 according to the use of TA during primary percutaneous coronary intervention (PCI). FAST-MI 2010 is a nationwide French registry that included 4,169 patients with acute myocardial infarction at the end of 2010 in 213 centers. Of those, 2,087 patients had STEMI, of whom 1,538 had primary PCI, with TA used in 671 (44%). Patients with TA were younger (61 ± 13.5 vs 63 ± 14 years), with a similar risk score of the Global Registry of Acute Coronary Events (140 ± 31 vs 143 ± 34) and a shorter median time from symptom onset (245 vs 285 minutes); location of acute myocardial infarction, history of myocardial infarction, PCI, or coronary artery bypass surgery did not differ significantly. Thirty-day mortality was 2.1% versus 2.1% (adjusted p = 0.18), and the rate of 1-year survival was 95.5% versus 94.8%. Using fully adjusted Cox multivariate analysis, hazard ratio for 1-year death was 1.13 (95% confidence interval 0.66 to 1.94). After propensity score matching (480 patients per group), 1-year survival was also similar with both strategies. In a real-world setting of patients admitted with STEMI, the use of TA during primary PCI was not associated with improved 1-year survival., (Copyright © 2014 Elsevier Inc. All rights reserved.)

The aim of this study was to identify predictors of 30-day and midterm mortality after transcatheter aortic valve implantation (TAVI) by means of a systemic review. TAVI was demonstrated to be safe and efficacious in patients with severe aortic stenosis. An accurate estimation of procedural risk of these patients represents an actual challenge. The PubMed and Cochrane Collaboration databases were systematically searched for studies reporting on the incidence and independent predictors of 30-day and midterm mortality. Adverse events were pooled with random effect, whereas independent predictors are reported as odds ratios (ORs) with 95% confidence intervals (CIs). A total of 25 studies with 8,874 patients were included (median age 82.5 ± 1.5 years, 54.6% women). At 30 days, 7.5% of patients (n = 663) died. At midterm follow-up (median 365 days, interquartile range 267 to 365 days), the cumulative mortality rate was 21.6% (n = 1,917). Acute kidney injury (AKI) stage ≥2 (OR 18.0, 95% CI 6.3 to 52), preprocedural hospitalization for heart failure (OR 9.4, 95% CI 2.6 to 35), periprocedural acute myocardial infarction (OR 8.5, 95% CI 2.6 to 33.5), and increased pro-brain natriuretic peptide (pro-BNP) levels (OR 5.4, 95% CI 1.7 to 16.5) were the most important independent predictors of 30-day mortality. Increased pro-BNP levels (OR 11, 95% CI 1.5 to 81), AKI stage 3 (OR 6.8, 95% CI 2.6 to 15.7), left ventricular ejection fraction <30% (OR 6.7, 95% CI 3.5 to 12.7), and periprocedural acute myocardial infarction (OR 6.5, 95% CI 2.3 to 18.1) represented the predictors of midterm mortality. In conclusion, in this large meta-analysis of patients undergoing TAVI, we found that high pro-BNP levels and postprocedural AKI were the strongest independent predictors of both 30-day and 1-year mortality. These findings may contribute to a better understanding of the risk assessment process of patients undergoing TAVI., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Better outcomes have been reported after percutaneous cardiac intervention in obese patients ("obesity paradox"). However, limited information is available on the effect of the body mass index on the outcomes after transcatheter aortic valve implantation (TAVI). We, therefore, sought to determine the effect of the body mass index on the short- and long-term outcomes in patients who underwent TAVI. The population consisted of 940 patients, of whom 25 (2.7%) were underweight, 384 had a (40.9%) normal weight, 372 (39.6%) were overweight, and 159 (16.9%) were obese. Overall, the obese patients were younger (79.7 ± 6.4 years vs 81.7 ± 7.3 and 80.8 ± 7.0 years, p = 0.008) and had a greater prevalence of preserved left ventricular and renal function. On univariate analysis, obese patients had a greater incidence of minor stroke (1.3% vs 0 and 0.3%, p = 0.03), minor vascular complications (15.7% vs 9.1% and 11.6%, p = 0.028) and acute kidney injury stage I (23.3% vs 10.7% and 16.1%, p <0.001). After adjustment, body mass index, as a continuous variable, was associated with a lower risk of mortality at 30 days (odds ratio 0.93, 95% confidence interval 0.86 to 0.98, p = 0.023) and no effect on survival after discharge (hazard ratio 1.01, 95% confidence interval 0.96 to 1.07, p = 0.73). In conclusion, obesity was associated with a greater incidence of minor, but no major, perioperative complications after TAVI. After adjustment, obesity was associated with a lower risk of 30-day mortality and had no adverse effect on mortality after discharge, underscoring the "obesity paradox" in patients undergoing TAVI., (Copyright © 2013 Elsevier Inc.

Our study objective was to assess the incidence, predictors, and implications of access site complications related to transfemoral transcatheter aortic valve implantation (TAVI). We pooled the prospective TAVI databases of 5 experienced centers in Europe enrolling only transfemoral cases for this analysis. Access site complications were defined according to the Valve Academic Research Consortium end-point definitions. The global transfemoral TAVI database contained 986 patients. Percutaneous access and closure was performed in 803 patients (81%) and a surgical strategy in 183 (19%). Incidences of major vascular complications, life-threatening/disabling bleeding, and major bleeding were 14.2%, 11%, and 17.8% respectively. In the patient cohort with a completely percutaneous access strategy, major vascular complications and life-threatening/disabling bleedings were related to closure device failure in 64% and 29%, respectively. Female gender (odds ratio 1.63, 95% confidence interval 1.12 to 2.36) and use of >19Fr system (2.87, 1.68 to 4.91) were independent predictors for major vascular complications. Female gender (odds ratio 2.04, 95% confidence interval 1.31 to 3.17), use of >19Fr system (1.86, 1.02 to 3.38), peripheral arterial disease (2.14, 1.27 to 3.61), learning effect (0.45, 0.27 to 0.73), and percutaneous access strategy (2.39, 1.16 to 4.89) were independently associated with life-threatening/disabling bleedings. In conclusion, transfemoral TAVI is associated with a >10% incidence of major vascular-related complications. A considerable number of these events is related to arteriotomy closure failure. Arterial sheath size and female gender are important determinants of major vascular complications and life-threatening/disabling bleeding., (Copyright © 2012 Elsevier Inc. All rights reserved.)
