Transapical Off-Pump Neochord Implantation in Case of Severe Mitral Regurgitation

摘要

Mitral regurgitation is common valvular heart disease and a major cause of congestive heart failure and death. It is most often associated with degenerative changes in mitral valve which leads to valve prolapse. Transapical off-pump mitral valve repair is a new minimally invasive procedure to treat mitral regurgitation. Here we report 64-year old female who suffered from grade III mitral regurgitation due to ruptured chorda and posterior leaflet P2/P3 segment prolapse. During surgery 4 artificial chordae were implanted and postoperative echocardiography results showed minimal residual grade I mitral regurgitation, therefore significant clinical improvement can be achieved with minimally invasive approach.
