Retrospective analysis assesses mid-term outcomes of bioprosthetic and mechanical valves in 172 patients, highlighting similar survival rates.
Key Points
Mid-term survival rates are comparable for bioprosthetic and mechanical valves after minimally invasive mitral valve replacement.
Postoperative arrhythmia was significantly more common in patients receiving bioprosthetic valves, occurring in 18.9% compared to 6.5% for mechanical valves.
The study included 172 patients aged 50 to 69 undergoing minimally invasive mitral valve replacement, following STROBE guidelines.
This research supports using minimally invasive approaches with either valve type in patients within the gray zone age group.
