Aims: The impact of sexuality in patients with significant tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI) is unknown. The aim of this study was to investigate sex-specific outcomes in patients with significant TR treated with TTVI vs. medical therapy alone.Methods and results: The Transcatheter Tricuspid Valve Therapies (TriValve) registry collected data on patients with significant TR from 24 centres who underwent TTVI from 2016 to 2021. A control cohort was formed by medically managed patients with ≥severe isolated TR diagnosed in 2015–18. The primary endpoint was freedom from all-cause mortality. Secondary endpoints were heart failure (HF) hospitalization, New York Heart Association (NYHA) functional status, and TR severity. One-year outcomes were assessed for the TriValve cohort and compared with the control cohort with the inverse probability of treatment weighting (IPTW). A total of 556 and 2072 patients were included from the TriValve and control groups, respectively. After TTVI, there was no difference between women and men in 1-year freedom from all-cause mortality 80.9% vs. 77.9%, P = 0.56, nor in HF hospitalization (P = 0.36), NYHA Functional Classes III and IV (P = 0.17), and TR severity >2+ at last follow-up (P = 0.42). Multivariable Cox-regression weighted by IPTW showed improved 1-year survival after TTVI compared with medical therapy alone in both women (adjusted hazard ratio 0.45, 95% confidence interval 0.23–0.83, P = 0.01) and men (adjusted hazard ratio 0.42, 95% confidence interval 0.18–0.89, P = 0.03).Conclusion: After TTVI in high-risk patients, there were no sex-related differences in terms of survival, HF hospitalization, functional status, and TR reduction up to 1 year. The IPTW analysis shows a survival benefit of TTVI over medical therapy alone in both women and men.

Objectives Most elderly patients affected by reflex vasodepressor syncope take one or more hypotensive drugs. The role of these drugs in causing syncope has not yet been established. We hypothesised that recurrence of syncope and presyncope can be reduced by discontinuing/reducing vasoactive therapy without increasing the risk of cardiovascular and neurological events. Methods This randomised, parallel, prospective, trial was conducted from January 2014 to March 2016 in four general hospitals. Of 328 initially screened participants, 58 patients (mean (SD) age 74±11 years) affected by vasodepressor reflex syncope, which was reproduced by tilt testing (n=54) or carotid sinus massage (n=4), were randomised to stop/reduce vasoactive therapy or to continue it. Primary end point was recurrence of syncope, presyncope or adverse events (defined as stroke, cerebral transient ischaemic attacks, worsening heart failure, myocardial infarction). Results Of 58 patients who were randomised, 55 completed the trial. After 1 month, systolic blood pressure was significantly higher in the ‘stop/reduce’ group than in the ‘continue’ group, in both supine (141±13 mm Hg vs 128±14 mm Hg; p=0.004) and standing (133±13 mm Hg vs 122±15 mm Hg; p=0.02) positions. During a mean follow-up of 13±7 months, the primary combined end point occurred in seven ‘stop/reduce’ patients (23%): three had syncope, three had presyncope and one had heart failure. Conversely, it occurred in 13 ‘continue’ patients (54%): 10 had syncope, 2 had presyncope and 1 had cerebral transient ischaemic attack. The log-rank p value was 0.02 and the HR was 0.37 (95% CI 0.15 to 0.91). Conclusions Recurrence of syncope and presyncope can be reduced by discontinuing/reducing vasoactive therapy in most elderly patients affected by reflex vasodepressor syncope.
