Totally thoracosopic mitral valve replacement (MVR) has been applied to mitral stenosis for many years. Three working ports are usually necessary, among which the longest port ranges from 6 to 8 cm. This study aimed to determine the safety and feasibility of the two-incision totally thoracoscopic approach for MVR, with the longest incision of 3 cm.From January 2014 to February 2016, 90 patients with mitral valve stenosis were retrospectively analyzed. Thirty-six (40%) patients were included in the two-incision group and 54 patients were operated on using the sternotomy approach. Perioperative variables and postoperative 3-month follow-up data were analyzed.All patients underwent MVR. Tricuspid valvuloplasty was performed in 23 (25.5%) patients with the Kay technique. The mean total surgery time, cardiopulmonary bypass, and cross-clamp times were longer in the two-incision group (266 ± 42 versus 200 ± 38 minutes; 156 ± 23 versus 121 ± 21 minutes; 100 ± 17 versus 80 ± 17 minutes, respectively) ( P The two-incision totally thoracoscopic approach for MVR is safe and feasible. Concomitant tricuspid valvuloplasty can be conveniently performed. However, further clinical data are needed in future studies.
