Revisiting Sex Equality With Transcatheter Aortic Valve Replacement Outcomes A Collaborative, Patient-Level Meta-Analysis of 11,310 Patients
AbstractBackgroundThere has been conflicting clinical evidence as to the influence of female sex on outcomes after transcatheter aortic valve replacement.ObjectivesThe aim of this study was to evaluate the impact of sex on early and late mortality and safety end points after transcatheter aortic valve replacement using a collaborative meta-analysis of patient-level data.MethodsFrom the MEDLINE, Embase, and the Cochrane Library databases, data were obtained from 5 studies, and a database containing individual patient-level time-to-event data was generated from the registry of each selected study. The primary outcome of interest was all-cause mortality. The safety end point was the combined 30-day safety end points of major vascular complications, bleeding events, and stroke, as defined by the Valve Academic Research Consortium when available.ResultsFive studies and their ongoing registry data, comprising 11,310 patients, were included. Women constituted 48.6% of the cohort and had fewer comorbidities than men. Women had a higher rate of major vascular complications (6.3% vs. 3.4%; p < 0.001), major bleeding events (10.5% vs. 8.5%; p = 0.003), and stroke (4.4% vs. 3.6%; p = 0.029) but a lower rate of significant aortic incompetence (grade ≥2; 19.4% vs. 24.5%; p < 0.001). There were no differences in procedural and 30-day mortality between women and men (2.6 % vs. 2.2% [p = 0.24] and 6.5% vs. 6.5% [p = 0.93], respectively), but female sex was independently associated with improved survival at median follow-up of 387 days (interquartile range: 192 to 730 days) from the index procedure (adjusted hazard ratio: 0.79; 95% confidence interval: 0.73 to 0.86; p = 0.001).ConclusionsAlthough women experience more bleeding events, as well as vascular and stroke complications, female sex is an independent predictor of late survival after transcatheter aortic valve replacement. This should be taken into account during patient selection for this procedure
Prevalence, predictors, and outcomes of patient prosthesis mismatch in women undergoing TAVI for severe aortic stenosis: Insights from the WIN-TAVI registry
Objective: To evaluate the incidence, predictors and outcomes of female patients with patient-prosthesis mismatch (PPM) following transcatheter aortic valve intervention (TAVI) for severe aortic stenosis (AS). Background: Female AS TAVI recipients have a significantly lower mortality than surgical aortic valve replacement (SAVR) recipients, which could be attributed to the potentially lower PPM rates. TAVI has been associated with lower rates of PPM compared to SAVR. PPM in females post TAVI has not been investigated to date. Methods: The WIN-TAVI (Women's INternational Transcatheter Aortic Valve Implantation) registry i
Incidence, determinants and clinical impact of definite stent thrombosis on mortality in women: From the WIN-DES collaborative patient-level pooled analysis.
BACKGROUND
Predictors and clinical outcomes of stent thrombosis (ST) in women have not been well investigated. Present study aimed to identify predictors of definite ST and its impact on mortality in women undergoing percutaneous coronary intervention (PCI).
METHODS
Patient-level data of women enrolled in 26 randomized trials of DES was pooled. The study population was stratified based on the presence or absence of definite ST. Cox proportional hazards models were used to determine the predictors of definite ST. To analyze the temporal impact of definite ST on mortality Cox regression with ST entered as time-updated covariate was used.
RESULTS
Of 11,557 patients undergoing PCI with stent implantation, definite ST occurred in 105 patients (0.9%) over median follow-up of 3years. Independent predictors of ST were age (HR 1.03 per year decrease, 95% CI 1.00-1.05; p=0.041), diabetes mellitus (HR 2.25, 95% CI 1.27-3.99; p=0.005), non-ST-segment elevation myocardial infarction (NSTEMI) at presentation (HR 1.97, 95% CI 1.04-3.75; p=0.037) and stent diameter (HR 3.76 per mm decrease, 95% CI 1.66-8.53; p=0.002). Compared to women without ST, the adjusted hazard ratios for mortality in the first 7days, 8-30days, and beyond 30days from ST were 115.81 (95% CI 68.96-194.47); 37.44 (95% CI 17.31-80.98); 3.54 (95% CI 2.20-5.69), respectively.
CONCLUSIONS
In this large-scale pooled analysis of women, definite ST was uncommon yet associated with substantial mortality risk, which peaked early and rapidly attenuated over time. Younger age, diabetes, NSTEMI and stent diameter were found to be predictors of ST
Influence of Sex on Long-Term Outcomes After Percutaneous Coronary Intervention with the Paclitaxel-Eluting Coronary Stent: Results of the TAXUS Woman Analysis
Intravascular Ultrasound Pulmonary Artery Denervation to Treat Pulmonary Arterial Hypertension (TROPHY1): Multicenter, Early Feasibility Study
Objectives: The aim of this study was to investigate whether therapeutic intravascular ultrasound pulmonary artery denervation (PDN) is safe and reduces pulmonary vascular resistance (PVR) in patients with pulmonary arterial hypertension (PAH) on a minimum of dual oral therapy. Background: Early studies have suggested that PDN can reduce PVR in patients with PAH. Methods: TROPHY1 (Treatment of Pulmonary Hypertension 1) was a multicenter, international, open-label trial undertaken at 8 specialist centers. Patients 18 to 75 years of age with PAH were eligible if taking dual oral or triple nonparenteral therapy and not responsive to acute vasodilator testing. Eligible patients underwent PDN (TIVUS System). The primary safety endpoint was procedure-related adverse events at 30 days. Secondary endpoints included procedure-related adverse events, disease worsening and death to 12 months, and efficacy endpoints that included change in pulmonary hemodynamic status, 6-min walk distance, and quality of life from baseline to 4 or 6 months. Patients were to remain on disease-specific medication for the duration of the study. Results: Twenty-three patients underwent PDN, with no procedure-related serious adverse events reported. The reduction in PVR at 4- or 6-month follow-up was 94 ± 151 dyn·s·cm−5 (p = 0.001) or 17.8%, which was associated with a 42 ± 63 m (p = 0.02) increase in 6-min walk distance and a 671 ± 1,555 step (p = 0.04) increase in daily activity. Conclusions: In this multicenter early feasibility study, PDN with an intravascular ultrasound catheter was performed without procedure-related adverse events and was associated with a reduction in PVR and increases in 6-min walk distance and daily activity in patients with PAH on background dual or triple therapy.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Female-specific survival advantage from transcatheter aortic valve implantation over surgical aortic valve replacement: Meta-analysis of the gender subgroups of randomised controlled trials including 3758 patients
Transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) is the first area of interventional cardiology where women are treated as often as men. In this analysis of the gender specific results of randomised controlled trials (RCTs) comparing TAVI with surgical aortic valve replacement (SAVR) we aimed to determine whether gender affects the survival comparison between TAVI and SAVR. We identified all RCTs comparing TAVI versus SAVR for severe AS and reporting 1 and/or 2 year survival. Summary odds ratios (ORs) were obtained using a random-effects model. Heterogeneity was assessed using the Q statistic and I2. Four RCTs met the criteria, totalling 3758 patients, 1706 women and 2052 men. Amongst females, TAVI recipients had a significantly lower mortality than SAVR recipients, at 1 year (OR 0.68; 95%CI 0.50 to 0.94) and at 2 years (OR 0.74; 95%CI 0.58 to 0.95). Amongst males there was no difference in mortality between TAVI and SAVR, at 1 year (OR 1.09; 95%CI 0.86 to 1.39) or 2 years (OR 1.05; 95%CI 0.85 to 1.3). The difference in treatment effect between genders was significant at both 1 year (pinteraction= 0.02) and 2 years (pinteraction= 0.04). In women TAVI has a 26 to 31% lower mortality odds than SAVR. In men, there is no difference in mortality between TAVI and SAVR
Outcomes After Transcatheter Aortic Valve Implantation in Men Versus Women.
Gender-based differences in outcomes after successful transcatheter aortic valve implantation (TAVI) in patients without an indication for oral anticoagulation have not been well studied. We aim to evaluate gender-based differences in clinical outcomes after TAVI. In the present analysis of the GALILEO (Global study comparing a rivaroxaban-based antithrombotic strategy to an antiplatelet-based strategy after transcatheter aortic valve replacement to optimize clinical outcomes) trial, patients with symptomatic severe aortic stenosis and who underwent successful TAVI were stratified by gender. The primary outcome was major adverse cardiac and cerebrovascular events (MACCEs), a composite of all-cause mortality or thromboembolic events (including any stroke, myocardial infarction, symptomatic valve thrombosis, systemic embolism, deep-vein thrombosis, or pulmonary embolism). Major bleeding was defined as a composite of major, life-threatening, or disabling Valve Academic Research Consortium-2 bleeding. Of 1,644 patients, 813 were female, and 831 were male. At baseline, female patients were older and at higher surgical risk (Society of Thoracic Surgeons risk score: 4.7 ± 3.6 versus 3.6 ± 3.0, p <0.0001) than male patients. After adjustment for differences in baseline clinical and procedural parameters, female patients had lower rates of MACCE (hazard ratio [HR] 0.69, 95% confidence interval [CI] 0.49 to 0.96), all-cause mortality (HR 0.54, 95% CI 0.34 to 0.87), and noncardiovascular mortality (HR 0.33, 95% CI 0.15 to 0.75) at a median of 17 months of follow-up. By landmark analyses, these differences appeared to emerge with a longer follow-up time. No significant differences in major, life-threatening, or disabling bleeding, cardiovascular mortality, and stroke were noted. In conclusion, compared with male patients, female patients with severe symptomatic aortic stenosis had a lower risk of MACCE and mortality but a similar risk of bleeding events after TAVI
Safety and efficacy of drug-eluting stents in women: a patient-level pooled analysis of randomised trials
BACKGROUND
The safety and efficacy of drug-eluting stents (DES) in the treatment of coronary artery disease have been assessed in several randomised trials. However, none of these trials were powered to assess the safety and efficacy of DES in women because only a small proportion of recruited participants were women. We therefore investigated the safety and efficacy of DES in female patients during long-term follow-up.
METHODS
We pooled patient-level data for female participants from 26 randomised trials of DES and analysed outcomes according to stent type (bare-metal stents, early-generation DES, and newer-generation DES). The primary safety endpoint was a composite of death or myocardial infarction. The secondary safety endpoint was definite or probable stent thrombosis. The primary efficacy endpoint was target-lesion revascularisation. Analysis was by intention to treat.
FINDINGS
Of 43,904 patients recruited in 26 trials of DES, 11,557 (26·3%) were women (mean age 67·1 years [SD 10·6]). 1108 (9·6%) women received bare-metal stents, 4171 (36·1%) early-generation DES, and 6278 (54·3%) newer-generation DES. At 3 years, estimated cumulative incidence of the composite of death or myocardial infarction occurred in 132 (12·8%) women in the bare-metal stent group, 421 (10·9%) in the early-generation DES group, and 496 (9·2%) in the newer-generation DES group (p=0·001). Definite or probable stent thrombosis occurred in 13 (1·3%), 79 (2·1%), and 66 (1·1%) women in the bare-metal stent, early-generation DES, and newer-generation DES groups, respectively (p=0·01). The use of DES was associated with a significant reduction in the 3 year rates of target-lesion revascularisation (197 [18·6%] women in the bare-metal stent group, 294 [7·8%] in the early-generation DES group, and 330 [6·3%] in the newer-generation DES group, p<0·0001). Results did not change after adjustment for baseline characteristics in the multivariable analysis.
INTERPRETATION
The use of DES in women is more effective and safe than is use of bare-metal stents during long-term follow-up. Newer-generation DES are associated with an improved safety profile compared with early-generation DES, and should therefore be thought of as the standard of care for percutaneous coronary revascularisation in women.

Effect of Increasing Stent Length on 3-Year Clinical Outcomes in Women Undergoing Percutaneous Coronary Intervention With New-Generation Drug-Eluting Stents: Patient-Level Pooled Analysis of Randomized Trials From the WIN-DES Initiative.
OBJECTIVES
The aim of this study was to examine whether stent length per patient and stent length per lesion are negative markers for 3-year outcomes in women following percutaneous coronary intervention (PCI) with new-generation drug-eluting stents (DES).
BACKGROUND
In the era of advanced stent technologies, whether stent length remains a correlate of adverse outcomes is unclear.
METHODS
Women treated with new-generation DES in 14 randomized trials from the WIN-DES (Women in Innovation and Drug-Eluting Stents) pooled database were evaluated. Total stent length per patient, which was available in 5,403 women (quartile 1, 8 to 18 mm; quartile 2, 18 to 24 mm; quartile 3, 24 to 36 mm; quartile 4, ≥36 mm), and stent length per lesion, which was available in 5,232 women (quartile 1, 8 to 18 mm; quartile 2, 18 to 20 mm; quartile 3, 20 to 27 mm; quartile 4, ≥27 mm) were analyzed in quartiles. The primary endpoint was 3-year major adverse cardiovascular events (MACE), defined as a composite of all-cause death, myocardial infarction, or target lesion revascularization.
RESULTS
In the per-patient analysis, a stepwise increase was observed with increasing stent length in the adjusted risk for 3-year MACE (p for trend <0.0001), myocardial infarction (p for trend <0.001), cardiac death (p for trend = 0.038), and target lesion revascularization (p for trend = 0.011) but not definite or probable stent thrombosis (p for trend = 0.673). In the per-lesion analysis, an increase was observed in the adjusted risk for 3-year MACE (p for trend = 0.002) and myocardial infarction (p for trend <0.0001) but not other individual endpoints. On landmark analysis for late event rates between 1 and 3 years, stent length per patient demonstrated weak associations with target lesion revascularization (p = 0.0131) and MACE (p = 0.0499), whereas stent length per lesion was not associated with higher risk for any late events, suggesting that risk was established early within the first year after PCI.
CONCLUSIONS
In this pooled analysis of women undergoing PCI with new-generation DES, increasing stent length per patient and per lesion were independent predictors of 3-year MACE but were not associated with definite or probable stent thrombosis
