Abstract: 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 endpoint was the (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 prior 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 endpoint was similar between groups (17.1% with SEV and 14.3% with BEV, p=0.25; HR 1.09, 95% CI 0.68-1.75). Conversely the crude rate and adjusted risk of new pacemaker implantation was higher with SEV than BEV (15% vs. 8.6%, p=0.001; HR 1.97, 95% CI 1.13-3.43). A subanalysis on new generation valves showed no difference in the need for pacemaker implantation between the two devices (10.1% vs. 8.0%, p=0.56). In conclusion, in contemporary TAVI, SEV are used more frequently in women with greater comorbidities. While there were no differences in unadjusted and adjusted risk of 1-year primary efficacy endpoint between the valve types, there was a greater need for permanent pacemakers after SEV implantation.

Introduction Transcatheter aortic valve implantation (TAVI) represents a safe and efficacious therapeutic strategy for patients with severe aortic stenosis [1-6]. Unlike coronary artery disease trials, women represent a significant proportion of enrolled patients in TAVI studies. The importance of gender on clinical outcomes following TAVI compared to surgical aortic valve replacement (SAVR) has been previously highlighted by the gender sub-analysis of the PARTNER (Placement of AoRTic TraNscathetER valve) trial and US Corevalve trial, demonstrating that for high risk female patients, TAVI is a better option than surgery[7, 8]. However, a patient-centered TAVI risk/ benefit assessment is required, and anatomical characteristics should be taken into account during patient and prosthetic valve selection. Although there are several devices available for TAVI, only two have been widely utilized both in the US and in Europe: the Edwards balloon expandable valve (BEV) and Medtronic self-expandable valve (SEV). Comparative studies evaluating BEV versus SEV have been limited by small sample size, lower female representation and/or indirect comparison [9-12]. While BEV and SEV are known to have specific features and anatomical requirements, potential gender-related differences in procedural and clinical outcomes have not been investigated so far. The aim of this study from the WIN-TAVI registry [13, 14] is 1) to compare the safety and efficacy of SEV and BEV in an all-female population with severe aortic valve stenosis and 2) to compare the effect of new generation SEV versus BEV.
Methods WIN TAVI (Women’s INternational Transcatheter Aortic Valve Implantation) is an international prospective registry comprising all consecutive female patients undergoing TAVI with any approved device in 19 centers in Europe and the US from March 2013 to December 2015, as previously described [13, 14]. All participating sites had institutional approval from the local ethical review board and the study was conducted according to the principles of the Declaration of Helsinki, International Organization for Standardization Guidelines, and Good Clinical Practice Guidelines. All patients who met the 4
eligibility criteria and provided written informed consent were enrolled in the study. Use of multidetector computed tomography (MDCT) of the aorta and iliofemoral axis was recommended to screen patients and direct the heart team’s choice on procedure type.
For the purpose of this analysis, we included all patients receiving an Edwards SAPIEN (Edwards Lifesciences, Irvine, CA, USA) or a Medtronic (Medtronic, Minneapolis, MN, USA) valve. Patients receiving other valve types were excluded from this analysis due to small numbers. Patients were divided based on valve type implanted into two groups: BEV and SEV. Procedural selection access, device type and use of pre and post-dilation was at the discretion of the treating physician. New-generation BEV (SAPIEN 3) and SEV (Evolut R) groups were also compared.
The primary study endpoint was 1-year efficacy endpoint according to the Valve Academic Research Consortium 2 (VARC-2) definition, comprising all-cause death, all stroke, myocardial infarction, hospitalizations for valve-related symptoms or worsening congestive heart failure or valve-related dysfunction (clinical presentation with valve thrombosis or endocarditis) [15]. Additional individual safety endpoints included: 30 day VARC-2 safety endpoint, 1-year all-cause death, cardiovascular death, myocardial infarction, stroke, bleeding (VARC-2 life-threatening or major bleeding), vascular complications, conduction disturbances and cardiac arrhythmias, coronary obstruction, ventricular perforation and conversion to open surgery. The Clinical and Data coordinating center for the study was at the Icahn School of Medicine at Mount Sinai (New York, New York). Adverse clinical events were reported by the centers through the electronic data collection system and were then reviewed and adjudicated by an independent clinical event committee of expert physicians using source documents provided by the sites. An independent core laboratory reviewed all MDCT exams. The study was endorsed by the SCAI-WIN (Society for Cardiovascular Angiography and Interventions - Women In Innovation) initiative.

Continuous baseline variables are expressed as mean±SD and were compared with the Student’s t-test. Categorical variables are expressed as percentages and were compared by the chi-square method. Clinical outcomes are reported using Kaplan Meier time-to-event methods and compared using the log-rank test. Hazard ratios (HR) and 95% confidence intervals (CI) were generated using multivariable Cox regression methods for risk of 1-year outcomes with SEV (reference= BEV). Variables for adjustment comprised age, body mass index, prior myocardial infarction, prior percutaneous coronary intervention or coronary artery bypass graft, prior stroke, chronic kidney disease, baseline atrial fibrillation, baseline permanent pacemaker, left ventricular ejection fraction, baseline pulmonary hypertension, surgical risk scores, high surgical risk judged by heart team, surgical aortic valve replacement rejected due to frailty, device size (>26mm vs. <=26mm), device generation, valve pre-dilation, valve post-dilation, post TAVI aortic regurgitation (AR) grade 2 or 3. A sensitivity analysis was carried out in patients receiving SEV or BEV for whom cardiac MDCT data was available (n=461). The sensitivity analysis took into account only MDCT variables that differed between the two groups in addition to the covariates previously listed for the primary analysis. A secondary analysis was carried out to compare new generation SEV Evolut R versus new generation BEV SAPIEN 3 valve (reference=BEV). All analyses were performed using Stata version 14.0 (StataCorp., College Station, Texas) and p-values<0.05 were considered significant.
Results Among 1019 patients enrolled in WIN-TAVI, 408 received an Edwards BEV, either SAPIEN XT or SAPIEN 3, and 461 received a Medtronic SEV, either Corevalve or Evolut R. Table 1 displays the baseline characteristics of patients according to valve type. SEV were more likely used in patients with a history of stroke, higher surgical risk scores and prior pacemaker implantation. Females receiving SEV had higher prevalence of pulmonary hypertension whereas those receiving BEV had high frailty as key reasons for rejecting SAVR (Fig 1). Echocardiographic characteristics were comparable between the two groups, 6
except for larger aortic annulus diameter in women receiving SEV. MDCT aortic root assessment confirmed larger mean annular diameter and circumference in SEV than BEV treated patients, whereas mean annulus area and the mean height from annulus to the left and right coronary ostia were similar between groups.
Procedural data are summarized in Table 2. The majority of BEV and SEV women were treated via the transfemoral route using local anaesthesia or conscious sedation without significant differences between the groups. SEV patients were more likely to receive larger sized valves and were more frequently treated with post-dilatation after implantation compared to BEV patients. No differences in procedural complications were noted between the groups. A significantly lower incidence of post-procedure AR grade ≥2 was observed in the BEV group (9.8% vs. 4.7%, p=0.007).
Clinical outcomes are presented in Table 3. No differences were observed between SEV and BEV in the occurrence of 30 day all-cause (4.3% vs. 3.7%, p=0.62) or cardiovascular death (4.3% vs. 3.4%, p=0.49). In addition, there were no statistically significant differences in the incidence of the VARC-2 combined safety endpoint (14.3% vs. 5.4%, p=0.87) or other secondary endpoints between the two groups. In contrast, the incidence of device failure requiring second valve deployment and new permanent pacemaker implantation was higher for patients treated with SEV. At 1-year, the crude incidence and adjusted risk of the primary VARC-2 efficacy endpoint was similar between BEV and SEV groups (17.1% with SEV and 14.3% with BEV, p=0.25; HR 1.09, 95% CI 0.68-1.75) (Figure 2). Conversely, the risk of new permanent pacemaker implantation was higher with SEV both before and after adjusting for confounders (15% vs. 8.6%, p=0.001; HR 1.97, 95% CI 1.13-3.43). Other secondary endpoints did not significantly differ between SEV and BEV treated women.

A sensitivity analysis was performed in those patients for whom cardiac MDCT data were available (n=461) (Figure 3). The sensitivity analysis confirmed that the risk of 1year VARC-2 efficacy endpoint was comparable between SEV and BEV, in keeping with the main analysis. However, once adjusted for MDCT characteristics, no difference was observed in the need for permanent pacemaker implantation (HR 1.25, 95% CI 0.63 - 2.48).
In the secondary analysis on new generation devices, we identified 224 Edwards SAPIEN 3 BEV and 79 Medtronic Evolut R SEV. Notably, the percentage of new generation devices used was significantly higher among the BEV than SEV group (p<0.001). Although the incidence of post procedural AR ≥2 grade was significantly lower for new generation devices (p<0.001), SEV prostheses were associated with a greater rate of AR compared to BEV prostheses (2.7% vs. 8.6%; p=0.04). Of note, no cases of grade 3 AR were recorded in any group. With the limitations of a small sample size, there were no significant differences in the rates of all crude and adjusted 1-year clinical outcomes including permanent pacemaker implantation (Table 4).
Discussion. The WIN-TAVI registry presents the largest observational single arm study to examine the safety and performance of contemporary TAVI in women [13, 14]. The main findings of this analysis by valve type are the following: 1) SEV were used more frequently in females with significant comorbidities and higher surgical risk; 2) there were no differences in crude incidence and adjusted risk of 1-year primary efficacy endpoint between valve types. Moreover, there were no significant differences in incidence and adjusted risk of 30 day or 1-year death between BEV and SEV; 3) the rate of grade 2 or 3 aortic regurgitation post TAVI implantation and new pacemaker implantation were higher with SEV. However, after adjusting for MDCT characteristics, there was no difference in the need for new pacemakers; 4) comparison of new generation devices confirmed no significant differences

between BEV and SEV in 1-year clinical outcomes including need for permanent pacemaker implantation.
Gender related studies are of great importance due to their impact on expert consensus statements and societal recommendations for selection of women undergoing TAVI. The current evidence suggests that TAVI is a better option than surgery for high-risk female patients[7, 16-18]. However, women experience greater procedural adverse events compared to men undergoing TAVI regardless of the valve type used [16, 18, 19], which may be due to anatomical differences in annular and left ventricular outflow tract dimension, coronary heights and peripheral vessel sizes [20, 21] . These characteristics should be taken into account during prosthetic valves selection for females undergoing TAVI. Some previous studies have reported a higher use of SEV among females compared with males [10, 19, 22]. In the current analysis from the WIN-TAVI registry, we observed that women receiving SEV prostheses had higher risk baseline profiles including higher surgical risk scores, higher prevalence of prior cerebrovascular events and pulmonary hypertension as well as larger aortic annular circumference on MDCT.
With respect to clinical outcomes between BEV and SEV treated females we observed no significant differences in the crude incidence and adjusted risk of the primary 1year efficacy endpoint or 1-year mortality. To date, the only randomized trial comparing the safety and efficacy of BEV and SEV, is the “Comparison of Transcatheter Heart Valves in High Risk Patients With Severe Aortic Stenosis: Medtronic CoreValve vs Edwards SAPIEN XT” (CHOICE) trial, limited by small sample size and the use of only first generation devices[9]. This trial did not find significant differences in the rate of all-cause mortality and cardiovascular mortality between BEV and SEV treated patients. Other studies including a meta-analysis comprising 35,347 patients have also confirmed similar survival after TAVI with both devices [9, 11, 12, 23]. However, in several studies, the risk of aortic regurgitation ≥2+, valve embolization, and, permanent pacemaker implantation was significantly higher 9
with SEV [9, 11, 23]. Notably, the percentage of males in the meta-analysis by Agarwal et al. was over 80% in both valve groups, making the results potentially difficult to apply to female patients [23]. Nevertheless, we also observed that overall SEVs were associated with a greater risk of post procedural aortic regurgitation ≥2+ (4.7% vs. 9.8%; p=0.007) and higher permanent pacemaker implantation rate (8.6% vs. 15.6%; p=0.001) compared to BEVs in women. Several factors may be implicated in this difference between valve types for paravalvular leak, including lower radial strength of the nitinol frame of SEV, an increased angulation between the left ventricular outflow tract and the ascending aorta in treated patients and deep implantation [9, 21]. Some data suggest that women undergoing TAVI experience less frequent undersizing than men who have larger annuli [7, 19]. Accordingly, females achieve a higher valve cover index and consequently lower incidence of residual severe AR [16], albeit this may occur predominantly with BEV [19]. Therefore, the larger annular dimensions observed in women receiving SEV in our study, might in part explain the higher rate of AR in this group compared to BEV treated women. Residual clinically significant paravalvular leak is rare with second generation TAVI devices, both balloon expandable S3 and Evolut R [24, 25]. In line with previous results, we found a reduced rate of postprocedural AR ≥2+ in females treated with newer generation prostheses. However, despite the higher incidence of post-dilation, new generation SEV were still associated with a greater rate of AR compared to new generation BEV.
Current evidence indicates that, age, pre-existent and procedure-induced conduction abnormalities together with the use of SEV are predictive of need for permanent pacemaker implantation with early-generation prostheses [26-28]. The large TAVI meta-analysis demonstrated more than three times higher incidence of new pacemaker after SEV compared to BEV at 30 days and 1 year [23]. We also observed significant differences in the frequency of permanent pacemaker implantation favoring BEVs among females undergoing TAVI. The rates were reduced with the new generation of SEVs and remained low with new 10
generation BEV. This has been correlated to the repositionable capability enabling more precise valve placement in the device landing zone thereby avoiding conduction disturbances associated with deep implantation [29, 30]. Aligned with these results, we noted comparable risk of pacemaker implantation with new generation SEV versus BEV.
The findings of our study may have important clinical implications for selection of female patients undergoing TAVI. Nevertheless, long term differences in device outcomes will drive physician choice of valve type for women. Our study has some limitations. First, this was an observational study without a control arm of males. Second, valve selection was at operator’s discretion, thus our analyses are subject to selection bias. Third, the majority of devices implanted in the study period were of the first generation. Fourth, despite the high rate of follow-up, lack of mandatory 1-year echocardiography led to missed opportunity for follow-up of paravalvular leak and may have led to underdiagnosis of TAVI dysfunction.
In conclusion, in a large group of women with severe aortic stenosis undergoing contemporary TAVI, SEV are more commonly used in women with severe comorbidities and higher surgical risk. Nevertheless, 1-year hard outcomes did not differ between SEV and BEV treated patients after adjustment. The risk of new pacemaker implantation after TAVI was higher with SEV, although the risk was mitigated with new generation valves.
