Background: Cumulative findings from various worldwide cohorts have shown sex-related differences in patients undergoing transcatheter aortic valve implantation (TAVI), yet data regarding procedural and long-term outcome are conflicting.
Aims: To evaluate sex-related differences regarding demographic and echocardiographic characteristics, procedural outcome and complications and long-term outcomes in patients undergoing TAVI.
Method: We evaluated patients who underwent TAVI for severe symptomatic aortic stenosis from a large TAVI registry in 4 tertiary hospitals in Israel between the years 2008-2016.
Results: Our final cohort included 1,359 female and 1,136 male patients. Female patients compared to male patients were less likely to present with a history of coronary artery disease (39% versus 67%, p<0.001), had a more favorable STS (Society of Thoracic Surgeons) score (4.8±4 versus 5.0±3.3, p<0.001), but were more frequently defined as frail (30% versus 17%, respectively, p<0.001). Female patients had a smaller valve area with higher peak and mean gradients compared to male patients (p
Conclusion: Female patients undergoing TAVI present with distinct baseline and procedure-related characteristics which may impact procedure related complications and long term outcome. Improved prognosis was observed among women versus men in the early TAVI period but outcomes seem to balance in the current period.
