Modi P, Rodriguez E, Hargrove WC, Hassan A, Szeto W, Chitwood WR Jr. Minimally invasive video-assisted mitral valve surgery: a twelve-year two center experience in 1178 patients. J Thorac Cardiovasc Surg 2009. Jun;137(6):1481-7. Epub 2009 Mar 29.
This reviewed a 2-institution experience with minimally invasive mitral valve surgery over a 12-year. A total of 1178 patients were included with mortality for isolated primary mitral valve repair and replacement of 0.2%and 3.6%, respectively. It concluded that video-assisted mitral valve surgery is safe with high rates of valve repair, low morbidity and excellent outcomes. Operative risk was increased if surgery was delayed until the onset of severe breathlessness or atrial fibrillation.
