Video-assisted thoracoscopic mitral valve replacement / 中华胸心血管外科杂志

ABSTRACT

Objective To summarize the experience of mitral valve replacement (MVR) using video-assisted thoracoscope. Methods 28 cases of MVR were performed through three right anterior ports under thoracoscopy using femorofemoral extracorporeal circulation. The aorta was cross-clamped and the myocardium was protected by coronary perfusion with cold cardioplegic. 33 patients underwent routine open approach MVR as control group. Results There was no death and no morbidity directly related to this approach. Comparing with control group, time of extracorporeal circulation was 82～146 (96?38)min vs. 80～132(92?31)min, cross-clamped 37～76(47?18)min vs. 34～72(45?13)min and ventilation time were 8.6～14.8(10.2?3.1)h vs. 8.3～15.9(11.3?3.4)h . The volume of drainage was 50～230 (72?28)ml in VATS group while 70～460(108?4.2)ml in control group((P
