| Popis: | Women comprise almost 50% of patients undergoing transcatheter aortic valve replacement (TAVR) and previous studies have indicated higher rates of procedural complications and bleeding in women compared to men. It is unknown whether men and women demonstrate a differential response to bivalirudin versus unfractionated heparin (UFH) in TAVR. We sought to evaluate outcomes by sex and type of anticoagulant from the Bivalirudin Versus Heparin Anticoagulation in Transcatheter Aortic Valve Replacement (BRAVO-3) trial of transfemoral TAVR.BRAVO-3 was a randomized multicenter trial comparing transfemoral TAVR with bivalirudin versus UFH (31 centers, n = 802). The primary endpoint was 48 h major bleeding defined as Bleeding Academic Research Consortium (BARC) type ≥3b. Major adverse cardiovascular events (MACE) were a composite of 30-day death, myocardial infarction, or stroke. Net adverse cardiovascular events (NACE) were a composite of BARC ≥3b bleeding or 30-day MACE. We examined the outcomes in men and women.The total cohort included 49% women (n = 391, 195 received bivalirudin and 196 UFH) and 51% men (n = 411, 209 received bivalirudin and 202 UFH). Women were older than men with fewer comorbidities including coronary artery disease, atrial fibrillation, diabetes but similar EuroSCORE I. Women received smaller sheath and device sizes compared with men without differences in the use of vascular closure devices. At 48-hr post-TAVR there was no difference in bleeding or vascular complications in women compared to men. The use of bivalirudin did not result in significantly lower bleeding at 48 hr or 30-days compared to UFH.There was no difference in early outcomes with bivalirudin versus UFH in men or women undergoing contemporary TAVR. © 2016 Wiley Periodicals, Inc. |
