Over the past 15 years, repair techniques, improved prostheses, retrograde cardioplegia, and enhanced exposure collectively have led to impressive advances in mitral valve surgery. Just as minimally invasive coronary surgery appears efficacious, cardiac valve operations using similar techniques are promising. Recently, Kaneko and associates1 reported videoscopic examination of the mitral valve during a commissurotomy done via a sternotomy. Early this year, port-access mitral replacements were done in Malaysia by the Stanford team using new aortic balloon occlusive technology.
