[PMID: 39059705 DOI: 10.1016/j.amjcard.2024.07.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2024] [Accepted: 07/20/2024] [Indexed: 07/28/2024]
Abstract
Patients with small aortic annuli (SAAs) are predominantly women. We sought to compare gender-based and propensity-matched outcomes of index transcatheter aortic valve replacement (TAVR) in patients with SAAs. In this retrospective institutional analysis (2012 to 2023), primary stratification was by gender. SAA was defined as an aortic valve annulus diameter <23 mm and the 30-day and 1-year outcomes were compared between the groups. A total of 3,911 patients underwent TAVR. Of those, 661 patients had an SAA, of whom 23.8% were men and 76.2% were women. Propensity matching (1:1) identified 152 pairs. The mean age was 81 years. History of surgical or percutaneous coronary intervention was more prevalent in men (72.4% vs 48%, p <0.001). Men had a higher incidence of postoperative pacemaker implantation (8.6% vs 3.3%, p = 0.05), whereas only women had iliofemoral dissections (4.6% vs 0%, p = 0.007). The rates of moderate (23.0% vs 25.7%) and severe (2.6% vs 0.7%) prosthesis-patient mismatch was not statistically significantly different between the groups (p = 0.364). The 30-day mortality was 0%, whereas the 1-year mortality was 4.3%, with no difference between the groups. An increase in preoperative creatinine was associated with higher risk of death (hazard ratio 1.206, 95% confidence interval 1.025 to 1.418, p = 0.02), whereas gender was not. Kaplan-Meier survival estimates (Log rank, p = 0.768) and cumulative incidence of stroke readmission (p = 0.842) were similar in both groups. In conclusion, the outcomes of TAVR in SAAs do not differ by gender, with safety and efficacy evident in men and women.

Abstract
Transcatheter aortic valve replacement (TAVR) is a well-established procedure using a catheter-introduced valve prosthesis for patients with severe aortic stenosis (AS). This retrospective study investigated sex-related differences in pre- and post-TAVR clinical and hemodynamic outcomes and analyzed data of the first 100 cases at Kaohsiung Medical University Chung-Ho Memorial Hospital (KMUH) between December 2013 and December 2021. Baseline characteristics, procedural outcomes, mortality rates, and echocardiographic parameters were analyzed and compared between sexes. Among the 100 patients, male (46%) and female (54%) were of similar age (mean age, male 86.0 years vs. female 84.5 years) and of the same severity of AS (mean pressure gradient, male 47.5 mmHg vs. female 45.7 mmHg) at the time receiving the TAVR procedure. Women had smaller aortic valve areas calculated by continuity equation (0.8 ± 0.3 cm2 vs. 0.7 ± 0.2 cm2, p < 0.001). In addition, women had better left ventricle ejection fraction (59.6 ± 14.0% vs. men 54.7 ± 17.2%, p < 0.01). In the post-TAVR follow-up, regression of left ventricle mass and dimension was better in women than in men. None of the patient died within 30 days after the procedure, and women tended to have a more favorable survival than men (2-year mortality and overall mortality rate in 8.3 year, women 9.1% and 22.2% vs. men 22.2% and 34.8%; p = 0.6385 and 0.1277, respectively). In conclusion, the sex-based difference in post-TAVR regression of LV remodeling suggests a need for sex-based evaluation for patients with severe AS and their post TAVR follow-up.

Abstract
Valvular heart diseases (VHDs) are a major cause of cardiovascular morbidity and mortality worldwide. As degenerative and functional mechanisms represent the main etiologies in high-income countries are degenerative and functional, while in low income countries etiologie is mostly rheumatic. Although therapeutic options have evolved considerably in recent years, women are consistently diagnosed at later stages of their disease, are delayed in receiving surgical referrals, and exhibit worse postoperative outcomes, compared to men. This difference is a result of the historical underrepresentation of women in studies from which current guidelines were developed. However, in recent years, important research, including more female patients, has been conducted and has highlighted substantial sex-specific differences in the etiology, diagnosis, and treatment of VHDs. Systematic consideration of these sex-specific differences in VHD patients is crucial for providing equitable healthcare and optimizing clinical outcomes in both female and male patients. Hence, this review aims to explore implications of sex-specific particularities for diagnosis, treatment options, and outcomes in women with VHDs.

Abstract
BACKGROUND Sex-specific characteristics in patients with aortic stenosis and small annuli undergoing transcatheter aortic valve implantation (TAVI) might affect clinical outcomes and hemodynamics. METHODS TAVI-SMALL 2 international retrospective registry included 1378 patients with severe aortic stenosis and small annuli (annular perimeter <72 mm or area < 400 mm2) treated with transfemoral TAVI at 16 high-volume centers between 2011 and 2020. Women (n = 1233) were compared with men (n = 145). One-to-one propensity score (PS) matching resulted in 99 pairs. Primary endpoint was incidence of all-cause mortality. Incidence of pre-discharge severe prosthesis-patient mismatch (PPM) and its association with all-cause mortality were investigated. Binary logistic and Cox regression were performed to adjust the treatment effect for PS quintiles. RESULTS Incidence of all-cause mortality at a median follow-up of 377 days did not differ between sex in the overall (10.3 vs. 9.8%, p = 0.842) and PS-matched (8.5 vs. 10.9%, p = 0.586) populations. After PS matching, pre-discharge severe PPM was numerically higher in women vs. men (10.2 vs. 4.3%), even though no evidence of a difference was found (p = 0.275). Within the overall population, women with severe PPM suffered a higher incidence of all-cause mortality when compared to those with less than moderate PPM (log-rank p = 0.024) and less than severe PPM (p = 0.027). CONCLUSIONS No difference in all-cause mortality at medium-term follow-up was observed between women and men with aortic stenosis and small annuli undergoing TAVI. Incidence of pre-discharge severe PPM was numerically higher in women than men, and it was associated with increased all-cause mortality in women.

Abstract
BACKGROUND There is a significant increase in morbidity and mortality in patients complicated by major bleeding following transcatheter aortic valve replacement (TAVR). It has become more challenging to manage such complications when the patient needs to be on anticoagulation or antiplatelet agent post-procedure to prevent thrombotic/embolic complications. METHODS We systematically reviewed all available randomized controlled trials and observational studies to identify incidence rates of gastrointestinal bleeding post-procedure. After performing a systematic search, a total of 8731 patients from 15 studies (5 RCTs and 10 non-RCTs) were included in this review. RESULTS The average rate of gastrointestinal bleeding during follow-up was 3.0% in randomized controlled trials and 1.9% among observational studies. CONCLUSION Gastrointestinal bleeding has been noted to be higher in the RCTs as compared to observational studies. This review expands knowledge of current guidelines and possible management of patients undergoing TAVR.

Abstract
In adults with severe aortic stenosis, sex and age differences in symptoms and diagnosis may lead to delays in intervention. Choice of intervention partly depends on expected longevity because bioprosthetic valves have limited durability, particularly in younger patients. Current guidelines recommend the following: a mechanical valve in younger adults (aged <50 years) if lifelong anticoagulation is possible and acceptable and a valve-sparing procedure is not possible; surgical mechanical or bioprosthetic aortic valve replacement (SAVR) in adults aged 50-65 years; and transcatheter aortic valve implantation (TAVI) for those aged >80 years based on lower mortality and morbidity compared to SAVR and adequate valve durability. For patients aged 65-80 years, the choice between TAVI and a bioprosthetic SAVR depends on expected longevity, which is greater in women than men, as well as associated cardiac and noncardiac conditions, valvular and vascular anatomy, estimated risk of SAVR versus TAVI and expected complications and patient preferences.

Sex Difference in Outcomes Following Transcatheter Aortic Valve Replacement in Bicuspid Aortic Stenosis. JACC Cardiovasc Interv 2022; 15:1652-1660. [PMID: 35981839 DOI: 10.1016/j.jcin.2022.06.036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 06/06/2022] [Accepted: 06/14/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND It is unknown whether the sex difference whereby female transcatheter aortic valve replacement (TAVR) candidates had a lower risk profile, a higher incidence of in-hospital complications, but more favorable short- and long-term survival observed in tricuspid cohorts undergoing TAVR would persist in patients with bicuspid aortic valves (BAVs). OBJECTIVES The aim of this study was to reexamine the impact of sex on outcomes following TAVR in patients with BAVs. METHODS In this single-center study, patients with BAVs undergoing TAVR for severe aortic stenosis from 2012 to 2021 were retrospectively included. Baseline characteristics, aortic root anatomy, and in-hospital and 1-year valve hemodynamic status and survival were compared between sexes. RESULTS A total of 510 patients with BAVs were included. At baseline, women presented with fewer comorbidities. Men had a greater proportion of Sievers type 1 BAV, higher calcium volumes (549.2 ± 408.4 mm3 vs 920.8 ± 654.3 mm3; P < 0.001), and larger aortic root structures. Women experienced more vascular complications (12.9% vs 4.9%; P = 0.002) and bleeding (11.1% vs 5.3%; P = 0.019) and higher residual gradients (16.9 ± 7.7 mm Hg vs 13.2 ± 6.4 mm Hg; P < 0.001), while men were more likely to undergo second valve implantations during index TAVR (6.3% vs 15.9%; P = 0.001). Death at 1 year was not significantly different between sexes (HR: 1.15; 95% CI: 0.56-2.35; P = 0.70). Bleeding (adjusted HR: 4.62; 95% CI: 1.51-14.12; P = 0.007) was the single independent predictor of 1-year death for women. CONCLUSIONS In patients with BAVs undergoing TAVR, women presented with fewer comorbidities, while men had a greater proportion of type 1 BAV, more calcification, and larger aortic roots. In-hospital outcomes favored men, with fewer complications except for the need for second valve implantation, but 1-year survival was comparable between sexes.

Abstract
Few data exist on late vascular complications (VCs) after transfemoral (TF) transcatheter aortic valve implantation (TAVI). The objective of this study was to evaluate the incidence and predictors of late access site VC after TF TAVI. A total of 128 patients (mean age: 80 ± 8 years, women: 52%) who underwent TF TAVI without major VC were included. A femoral US-Doppler evaluation was performed in all patients at a median of 5 (3 to 15) months after the procedure, and 76 patients (59.4%) also had a preprocedural ultrasound (US)-Doppler examination. The impact of baseline and procedural factors (including the use of simple 2 Proglides or complex additional Proglide or Angioseal device on top of the 2 Proglide technique, hemostasis techniques, and the use of balloon dilation for optimizing femoral hemostasis) were evaluated. The follow-up US-Doppler evaluation detected 2 asymptomatic VCs (1.6%), and 5 (3.9%) patients exhibited significant femoral stenosis (peak systolic velocity [PSV] ≥300 cm/s). Female gender (p <0.001) and smaller femoral diameter (p = 0.045) were associated with higher femoral PSV values. In those patients who underwent a pre-TAVI femoral US-Doppler, the median PSV values after TAVI were higher compared with those obtained pre-TAVI (p <0.001), but similar results were found for the contralateral femoral arteries. A complex hemostasis technique or the use of balloon optimization at the puncture site was not associated with any increase in PSV values. In conclusion, percutaneous femoral hemostasis after TAVI was associated with a low rate of late VC. The results were similar irrespective of the hemostasis technique and the use of balloon dilation at the puncture site, but women and a smaller femoral size were associated with increased PSV values. Further studies are needed to determine the optimal femoral hemostasis technique in TAVI procedures.

Gender Differences in Age-Stratified Inhospital Outcomes After Transcatheter Aortic Valve Implantation (from the National Inpatient Sample 2012 to 2018). Am J Cardiol 2022; 167:83-92. [PMID: 34991843 DOI: 10.1016/j.amjcard.2021.11.038] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 11/21/2021] [Accepted: 11/23/2021] [Indexed: 01/09/2023]
Abstract
Contemporary data on gender differences in outcomes after transcatheter aortic valve implantation (TAVI), after stratification by age, remain limited. We studied age-stratified (60 to 70, 71 to 80, and 81 to 90 years) inhospital outcomes by gender after TAVI from the National Inpatient Sample database between 2012 and 2018. We analyzed National Inpatient Sample data using the International Classification of Diseases, Clinical Modification, Ninth Revision, and Tenth Revision claims codes. Between the years 2012 and 2018, a total of 188,325 weighted hospitalizations for TAVI were included in the analysis. A total of 21,957 patients were included in the 60 to 70 age group (44% females), 60,770 (45% females) in the 71 to 80 age group, and 105,580 (50% females) in the 81 to 90 age groups, respectively. Propensity-matched inhospital mortality rates were significantly higher for females than males for the age group of 81 to 90 years (3.0% vs 2.1%, p <0.01). Vascular complications and a need for blood transfusions remained significantly higher for females on propensity-matched analysis across all categories of ages. Conversely, acute kidney injury and the need for pacemaker implantation remained significantly higher for males across all age groups. In conclusion, we report that mortality is higher in female patients who underwent TAVI between the ages of 81 to 90. Moreover, the female gender was associated with higher vascular complications and bleeding requiring transfusions. Conversely, the male gender was associated with higher rates of pacemaker implantation and acute kidney injury.

Abstract
As populations age worldwide, the burden of valvular heart disease has grown exponentially, and so has the proportion of affected women. Although rheumatic valve disease is declining in high-income countries, degenerative age-related causes are rising. Calcific aortic stenosis and degenerative mitral regurgitation affect a significant proportion of elderly women, particularly those with comorbidities. Women with valvular heart disease have been underrepresented in many of the landmark studies which form the basis for guideline recommendations. As a consequence, surgical referrals in women have often been delayed, with worse postoperative outcomes compared with men. As described in this review, a more recent effort to include women in research studies and clinical trials has increased our knowledge about sex-based differences in epidemiology, pathophysiology, diagnostic criteria, treatment options, outcomes, and prognosis.

Female gender and the clinical and periprocedural profile and clinical outcomes of transcatheter aortic valve implantation: experiences of a tertiary Polish centre. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2020; 16:436-443. [PMID: 33598017 PMCID: PMC7863829 DOI: 10.5114/aic.2020.101769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 10/12/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Despite the establishment of multiple factors influencing short- and mid-term outcomes in patients treated with transcatheter aortic valve implantation (TAVI), the real-world data on the association between gender and outcomes after TAVI remain conflicting. Aim To evaluate the association of female gender with the clinical and periprocedural characteristics along with in-hospital, short- and medium-term outcomes of patients treated with TAVI in comparison with male patients. Material and methods Data from the prospective, single-centre registry of consecutive patients with severe AS referred for TAVI from 26 November 2008 to 31 December 2018 were analysed retrospectively. The study population comprised 275 patients who were divided by gender. The primary endpoint of the study was all-cause mortality at 1 year. Results Women constituted 132 (48.0%) of the overall population. Women were significantly older, but had a significantly higher left ventricular ejection fraction (LVEF) and had less frequently undergone coronary artery bypass grafting (CABG) before TAVI. The implantation success rate was comparable between genders, but women less frequently required implantation of a pacemaker after TAVI, although they more frequently required blood transfusion due to severe bleeding. The primary endpoint occurred in 13.6% of women and 7.7% of men (p = 0.12). Conclusions Despite advanced age and prevalence of cardiovascular risk factors, the overall short- and medium-term mortality in patients treated with TAVI in our analysis of the real-world population remains relatively low. Although women seemed to have a slightly better clinical baseline profile, their in-hospital, 30-day, 6-month and 12-month outcomes did not differ significantly from the male patients.

Abstract
In the current state of interventional cardiology, the ability to offer advanced therapies to patients who historically were not surgical candidates has grown exponentially in the last few decades. As therapies have expanded in complex coronary and structural interventions, the nuances of treating certain populations have emerged. In particular, the role of sex-based anatomic and outcome differences has been increasingly recognized. As guidelines for cardiovascular prevention and treatment for certain conditions may vary by sex, therapeutic interventions in the structural and percutaneous coronary areas may also vary. In this review, we aim to discuss these differences, the current literature available on these topics, and areas of focus for the future.

Abstract
Previous studies indicate that women who underwentwho underwent transcatheter aortic valve implantation (TAVI) have poorer 30-day outcomes compared with men. However, the effect of gender as a prognostic factor for long-term outcomes following TAVI remains unclear. Between 2008 and 2018, all patients (n = 683) who underwent TAVI in 2 centres in Melbourne, Australia were prospectively included in a registry. The primary end-point was long-term mortality. The secondary end points were Valve Academic Research Consortium-2 (VARC-2) in-hospital complications and mortality at 30-days and 1-year. Of 683 patients, 328 (48%) were women. Women had a higher mean STS-PROM score (5.2 ± 3.1 vs 4.6 ± 3.5, p < 0.001) but less co-morbidities than men. Women had a significantly higher in-hospital bleeding rates (3.3% vs 1.0%, Odds Ratio 4.21, 95% confidence interval [CI] 1.16 to15.25, p = 0.027) and higher 30-day mortality (2.4% vs 0.3%, hazard ratio [HR] 8.75, 95% CI 1.09 to 69.6, p = 0.040) than men. Other VARC-2 outcomes were similar between genders. Overall mortality rate was 36% (246) over a median follow up of 2.7 (interquartile rang [IQR] 1.7 to 4.2) years. Median time to death was 5.3 (95% CI 4.7 to 5.7) years. One-year mortality was similar between genders (8.3% vs 7.8%), as was long-term mortality (HR = 0.91, 95% CI 0.71 to 1.17, p = 0.38). On multivariable analysis, female gender was an independent predictor for 1-year mortality (HR = 2.33, 95% CI 1.11 to 4.92, p = 0.026), but not long-term mortality (HR = 0.78, 95% CI 0.54 to 1.14, p = 0.20). In the women only cohort, STS-PROM was the only independent predictor of long-term mortality (HR 1.88, 95% CI 1.42 to 2.48, p < 0.001). In conclusion, women had higher rates of peri-procedural major bleeding and 30-day mortality following TAVI. However, long-term outcomes were similar between genders.

Abstract
Left ventricular (LV) remodeling with aortic stenosis (AS) appears to differ according to sex, but reverse remodeling after transcatheter aortic valve implantation (TAVI) has not been elucidated in a Japanese population. This study aims to determine whether any sex-related differences in LV or reverse remodeling after TAVI exist in the context of severe AS.Of 208 patients who received TAVI for severe AS in our institution, 100 (men, 42; mean age, 83.0 ± 4.9 years) underwent transthoracic echocardiography before and 3 months after TAVI. Despite similar valvular gradients, women with severe AS had lower indexed LV mass (LVMi) than did men (152.3 ± 35.4 versus 173.2 ± 44.6 g/m2, P = 0.005), with smaller indexed LV end-diastolic (LVEDVi) (50.2 ± 13.3 versus 61.4 ± 20.7 mL/m2, P = 0.001) and end-systolic (LVESVi; 17.9 ± 8.7 versus 24.3 ± 13.8 mL/m2, P = 0.006) volumes. After TAVI, women (-6.0% ± 14.4%) had higher reduction in the rate of change of relative wall thickness (RWT) than did men (4.4% ± 19.0%, P = 0.003). Men (-8.9% ± 3.9%) had higher reduction in the rate of change of LVEDVi than did women (1.5% ± 3.3%, P = 0.045). Incidence of LV reverse remodeling defined as a reduction in LVESV of >15% was significantly higher in men (50%) than in women (26%, P = 0.013).In addition to sex differences in the pattern of LV remodeling with AS, reverse LV remodeling after TAVI also differed between sexes.

Abstract
Introduction: In aortic stenosis (AS), there are clear sex differences in clinical presentation, left ventricular (LV) response to pressure overload, and pathophysiology of valvular calcification. These differences may affect outcome following valve intervention.Area covered: This review aims to discuss sex differences in clinical presentation, pathophysiology of aortic valve calcification, LV remodeling in view of historic and recent echocardiographic and cardiac magnetic resonance imaging studies, and outcome after valve intervention. In addition, it will also provide some brief insights on the exercise physiology in women and men with AS.Expert commentary: Women at presentation are often older, have higher prevalence of hypertension and diastolic dysfunction, while men are younger, and more often have a bicuspid aortic valve and higher atherosclerotic disease burden. Men have more valve calcification than women for a given severity of AS and develop different patterns of LV remodeling and myocardial fibrosis. Although women tend to walk shorter on treadmill and achieve lower metabolic equivalents, they achieve similar peak heart rates and blood pressure, and the frequency of revealed symptoms during exercise test is comparable in both sexes. Men are more likely to undergo a surgical AVR with better outcome, while women have generally better outcome after TAVI.

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 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.

Abstract
Transcatheter aortic valve implantation (TAVI) has emerged as an alternative treatment for severe symptomatic aortic stenosis in patients who are not suitable for surgery or are at high surgical risk. Approximately 50% of patients undergoing TAVI are female and this is reflected by a higher inclusion rate of women in TAVI trials. However, women undergoing TAVI have different baseline clinical characteristics in comparison to men, with fewer comorbidities and a more preserved left ventricular ejection fraction. This translates into favourable outcomes after TAVI, despite a higher rate of peri-procedural complications. This article discusses gender differences in terms of presentation, procedural characteristics and post-procedural results in patients with aortic stenosis undergoing TAVI, with particular focus on possible sex-specific factors affecting outcome.

Abstract
BACKGROUND Transfemoral aortic valve replacement (TAVR) is a guideline-recommended treatment option for patients with severe aortic valve stenosis. Women and men present with different baseline characteristics, which may influence procedural outcomes. OBJECTIVES This study sought to evaluate differences between women and men undergoing transfemoral TAVR across the globe during the last decade. METHODS The CENTER (Cerebrovascular EveNts in patients undergoing TranscathetER aortic valve implantation with balloon-expandable valves versus self-expandable valves)-collaboration was a global patient level dataset of patients undergoing transfemoral TAVR (N = 12,381) from 2007 to 2018. In this retrospective analysis, the study examined differences in baseline patient characteristics, 30-day stroke and mortality, and in-hospital outcomes between female and male patients. The study also assessed for temporal changes in outcomes and predictors for mortality per sex. RESULTS We included 58% (n = 7,120) female and 42% (n = 5,261) male patients. Women had higher prevalence of hypertension and glomerular filtration rate <30 ml/min/1.73 m2 but lower prevalence of all other traditional cardiovascular comorbidities. Both sexes had similar rates of 30-day stroke (2.3% vs. 2.5%; p = 0.53) and mortality (5.9% vs. 5.5%; p = 0.17). In contrast, women had a 50% higher risk of life-threatening or major bleeding (6.7% vs. 4.4%; p < 0.01). Over the study period, mortality rates decreased to a greater extent in men than in women (60% vs. 50% reduction; both p < 0.001), with no reductions in stroke rates over time. CONCLUSIONS In this global collaboration, women and men had similar rates of 30-day mortality and stroke. However, women had higher rates of procedural life-threatening or major bleeding after TAVR. Between 2007 and 2018, mortality rates decreased to a greater extent in men than in women.

Abstract
We evaluated temporal trends in gender-related differences in patients who underwent transcatheter aortic valve implantation (TAVI) for severe symptomatic aortic stenosis from a multicenter TAVI registry during the years 2008 to 2016. Our final cohort included 1,159 males and 1,370 females, with a median follow-up of 2.3 (IQR 1.2, 4.4) years. For temporal trends analysis, the entire population was divided according to period of procedure: 2008 to 2012 and 2013 to 2016. During the 2008 to 2012 period, the rates of in-hospital aortic paravalvular leak, myocardial infarction, pacemaker implantation, and stroke were higher among men than women, but became comparable between the gender during the 2013 to 2016 period. Multivariate analysis demonstrated that female patients who underwent TAVI between the years 2008 and 2012 had a 26% lower risk of death compared with male patients (p = 0.004), but there were no gender-related differences in mortality risk between the years 2013 and 2016 (hazard ratio 1.07, p = 0.6; gender-by-year of procedure, p = 0.027 for interaction). In conclusion, the favorable long-term prognosis described in female patients during the earlier TAVI period seemed to diminish with contemporary TAVI. This might be attributed to current technological advances and improved valve sizing, with a more significant benefit in favor of male patients.

Herz 2018; 45:375-381. [PMID: 30483815 PMCID: PMC7286940 DOI: 10.1007/s00059-018-4740-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Revised: 07/18/2018] [Accepted: 07/28/2018] [Indexed: 11/16/2022]
Abstract
Objectives The aim of this study is to investigate the sex-specific aortic root anatomy in patients with bicuspid aortic valve (BAV). Patients and methods This retrospective study includes 73 consecutive patients with BAV who underwent CT evaluation before transcatheter aortic valve replacement (TAVR) between July 2013 and April 2017 in the Second Affiliated Hospital of Zhejiang University. Result The size of the annulus, diameter and height of the sinotubular junction (STJ), height of the coronary artery ostia, and dimension of the aorta were measured. Women had significantly smaller annulus parameters (mean diameter: 23.4 ± 1.8 vs. 26.1 ± 2.1 mm; area: 425.3 ± 59.4 vs. 527.4 ± 84.6 mm2; perimeter: 74.3 ± 5.2 vs. 83.2 ± 6.4 mm), and STJ diameter (29.7 ± 3.1 vs. 32.6 ± 4.5 mm) than men (p < 0.01 for all), even after adjustment for their smaller body surface area (BSA). Dimension of aorta and height of right coronary artery were also significantly smaller in women, although not when indexing for the BSA. The left ventricular ejection fraction of women is significantly higher than that of men before discharge (60.2 ± 9.7% vs. 53.7 ± 13.6%, p = 0.01). There were no differences between women and men in the all-cause 30-day and 1‑year mortality. Conclusion Women with BAV had smaller annulus and STJ diameter after indexing for BSA, reflecting a sex-specific difference. There were no differences in 30-day and 1‑year mortality between the two groups.

Abstract
Gender differences in the pathophysiology of atherosclerosis, cardiovascular risk factors, and diagnosis of coronary artery disease and valvular heart disease are well known. Such differences have also been outlined in the management and outcomes after acute coronary syndromes and valvular repair. Regarding the atherosclerotic process, pathological experimental studies suggest that plaque composition and burden may differ by gender. Female gender is associated with worse outcomes in the case of ischemic heart disease and, compared with men, women are less likely to undergo interventional cardiac procedures and sustain worse outcomes. In the setting of valvular heart disease (VHD), transcatheter aortic valve implantation (TAVI) and percutaneous edge-to-edge mitral valve repair are now well-established procedures with high success rates. In women with moderate to severe aortic stenosis, subgroup analyses in TAVI trials have demonstrated gender-related differences suggesting female gender as beneficial in terms of short-, mid-, and long-term outcomes. Similarly, several studies reported different procedural challenges and outcomes in males and females following surgical and percutaneous mitral valve repair. These diverse findings emphasize the necessity to provide gender-specific analyses of interventional methods. This review highlights gender differences in the epidemiology, pathophysiology, treatment options and clinical outcomes of the conditions mentioned above.

Abstract
Aortic stenosis (AS) is the most common valvular disease in the elderly and is associated with poor outcomes. Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) in high-risk patients. Herein, we describe the gender-related differences in baseline characteristics and pathophysiologic response to severe AS, imaging considerations unique to females, and short- and long-term outcomes after TAVR. Women undergoing TAVR are older and frailer, have less cardiovascular comorbidities, smaller femoral artery size, better left ventricular systolic function, hypertrophied and small left ventricles leading to a higher incidence of paradoxical low-flow low-gradient AS, and a greater prevalence of porcelain aorta, smaller aortic annulus size, and lower coronary ostia heights. Imaging and histopathological data also suggests a sex-related myocardial response to pressure overload from AS. Women experience more vascular complications and blood transfusion requirements, serious procedural complications, and a greater incidence of stroke, but have better long-term outcomes than men. Patient-prosthesis mismatch, which is a concern in patients with a small aortic annulus size undergoing SAVR, has not been problematic with TAVR. The aforementioned findings suggest that TAVR may be preferable for women with severe AS. Further studies are warranted to directly compare TAVR with SAVR in women.

Abstract
Aortic stenosis (AS), 1 of the most common valve diseases in developed countries, carries a poor prognosis if left untreated. Transcatheter aortic valve replacement (TAVR) has become the standard of care for high-risk and inoperable patients with severe aortic stenosis (AS). Women represent a significant proportion of patients with severe AS and demonstrate specific clinical, anatomic, and pathophysiological features that are evident both before and after valve replacement. In this review, we discuss these features as well as the outcomes of women undergoing TAVR for AS.
