Mitral valve repair is preferred to replacement in @entity884 , but in the active phase, it often requires extensive debridement of infected tissue and complex reconstruction. We investigated 22 consecutive native mitral valve operations during active-phase @entity884 . The time from initiation of medical treatment to operation was 16.8    16.4 days. Mitral valve repair was performed in 15 (68.2%) @entity1 , using prosthetic annuloplasty in 14, an autologous pericardial patch in 11, and artificial chordal replacement in 9. Hospital mortality was 9.1% (2 @entity1 ), due to @entity510 and @entity55 . One @entity1 died 26 months after valve replacement due to @entity712 . The postoperative left ventricular end-diastolic dimension was significantly smaller (45.7    5.6 vs. 53.3    10.2 mm) and ejection fraction was significantly higher (57.0%    14.7% vs. 40.1%    8.2%) in @entity1 who underwent valve repair compared to those who had valve replacement. @entity339 requiring reoperation occurred in 3 @entity1 during follow-up. Mitral valve repair is feasible in active-phase @entity884 , and results in improved regression of left ventricular dimensions compared to valve replacement. However, complex mitral valve repair with extensive leaflet resection may not have long-term durability.
