Clinical Outcomes of Edwards Lifesciences MITRIS RESLILA Mitral Valve in the Asian Population

This study is a prospective, investigator-Investigator initiated, multicenter observational study that aims to competitively register 200 patients who have undergone mitral valve replacement surgery with the MITRIS RESILIA mitral valve at participating institutions to collect real clinical outcomes.

This study will collect data on clinical outcomes obtained during standard care for patients who undergo mitral valve replacement surgery using the MITRIS RESILIA mitral valve in South Korea.

The aim is to recruit 200 patients using the MITRIS RESILIA mitral valve (competitive recruitment, no more than 100 per institution) over a period of two years.

All patients registered in the registry will be followed for five years. Follow-up assessments will occur at 6 months, 1 year, 2 years, 3 years, and 5 years post-surgery. Including the 2-year registration period and 5 years of follow-up for result analysis, the total study duration is expected to be approximately 7.5 years. However, the overall duration may vary depending on the rate of participant registration.
