Abstract

AIMS:

To assess outcomes after transcatheter aortic valve implantation (TAVI) according to sex, with the two available valves and four recognised delivery approaches.

METHODS AND RESULTS:

VARC outcomes are reported according to sex for 305 high-risk patients consecutively treated in our centre, via available access routes utilising the Edwards SAPIEN™/SAPIEN™ XT or the Medtronic CoreValve ReValving System® devices. Three hundred and five patients underwent TAVI: 52.1% male and 47.9% female. Females had a smaller body surface area (1.84±0.16 m² vs. 1.70±0.16 m²; p<0.001) and aortic annulus (24.4±1.6 mm vs. 22.6±1.7 mm; p<0.001) with increased symptoms (NYHA Class III/IV 61.6% vs. 73.6%; p=0.026). Conversely, men had more comorbidities: diabetes mellitus (35.2% vs. 21.9%; p=0.010), chronic kidney disease (41.8% vs. 23.3%; p=0.001), chronic obstructive pulmonary disease (45.3% vs. 30.1%; p=0.006) and previous myocardial infarction (28.3% vs. 14.4%; p=0.003). Thirty-day mortality was 4.7% with no difference between groups. There was a trend for females to develop more major vascular complications (11.9% vs. 19.9%; p=0.058). Notably, females required more blood transfusion (38.4% vs. 50.0%; p=0.041). No differences were observed in device success (92.5%; p=0.667), combined safety endpoint (61.8%; p=0.211) or combined efficacy endpoint (72.0%; p=0.889).

CONCLUSIONS:

Female sex was a predictor of major vascular complications with females requiring more transfusion. No differences were noted amongst patients undergoing TAVI in composite safety and efficacy endpoints according to sex.
