Long-term Outcomes Following Mechanical or Bioprosthetic Aortic Valve Replacement in Young Women.

Background: Studies performed to date reporting outcomes after mechanical or bioprosthetic aortic valve replacement (AVR) have largely neglected the young female population. This study compares long-term outcomes in female patients aged < 50 years undergoing AVR with either a mechanical or bioprosthetic valve.

Methods: In this propensity-matched study, we compared outcomes after mechanical AVR (n = 57) and bioprosthetic AVR (n = 57) between 2004 and 2018.

Rapid deployment valves versus conventional tissue valves for aortic valve replacement.

Objectives: Rapid deployment valves have been developed as a means to adjust for limitations in transcatheter aortic valve replacement and surgical aortic valve replacement for the management of aortic valve disease. To date, many studies have shown that although rapid deployment valves facilitate a shorter surgical aortic valve replacement, they offer no clinical benefit. The purpose of this study was to compare the outcomes of rapid deployment valves with conventional surgical aortic valve replacement.
