Minimally invasive surgery of mitral valve (MIS-MV)

Following the revision of the therapeutic guideline of ACC/AHA in (Circulation 114:450-527, 2006), the incidence of mitral valve repair in asymptomatic patients with moderate or severe mitral valve regurgitation has increased. For mitral valve repair, the quality and outcomes as well as lower invasive procedure are important to obtain the confidence of cardiologists and ensure request of early phase operation from cardiologists. With recent innovations of technologies and the development of revolutionary techniques, minimally invasive surgery of the mitral valve (MIS-MV) has become a widespread surgical option of mitral valve repair. It is vital, however, that careful preoperative assessment, and planning of the approach and perfusion strategy are put in place to perform MIS-MV safely.
