Long-Term Outcomes and Durability of the Mosaic Mitral Valve Bioprosthesis in Adults Under 65

What this Trial Is About

This research aims to evaluate the long-term outcomes and durability of the Medtronic Mosaic mitral valve bioprosthesis in patients under 65 years of age who have undergone mitral valve replacement. While the safety and effectiveness of this bioprosthetic valve in the aortic position are well documented, fewer studies have examined its performance and patient outcomes in the mitral position, especially in younger patients where mechanical valves are more commonly recommended. This study seeks to provide valuable information on valve efficacy, stability, and post-operative results for this specific group. The study focuses on patients who received the Mosaic mitral valve bioprosthesis at ProMedica Toledo Hospital and were under the age of 65 at the time of surgery. It observes these patients over time to assess valve durability and patient health outcomes. There are no experimental treatments or interventions since this is an observational study reviewing existing cases. The investigation covers multiple years, analyzing data from January 2001 through December 2025. Participants involvement includes monitoring mortality, morbidity, valve stability, and freedom from re-operation over the study period. Researchers will collect and review medical records and follow-up data to measure these outcomes. The study will help understand how well the valve performs in the mitral position among younger patients and aims to inform future treatment choices and valve replacement timing. The total observation period extends until July 1, 2027.
