Abstract：Objective To investigate the safety and feasibility of double-hole total thoracoscopic mitral valve replacement with double orifice. Methods The clinical data of 90 patients with mitral stenosis admitted to Department of Cardiac Surgery, Beijing Chaoyang Hospital Capital Medical University from January 2015 to December 2016 were retrospectively analyzed. A total of 36 (40%) patients underwent complete thoracoscopic mitral valve replacement by double-hole total thoracoscopic approach. Fifty-four patients underwent conventional thoracotomy for mitral valve replacement. Perioperative variables and one year postoperative follow-up data were analyzed. Results Twenty-three patients (25.5%) underwent tricuspid valvuloplasty at the same time. There were no significant differences in total operation time, cardiopulmonary bypass time and myocardial blood supply blockade time between the two groups (P ＞ 0.05). The mean mechanical ventilation time of the total thoracoscopy group was shorter than that of the conventional thoracotomy group (P ＜ 0.05). The drainage volume of thoracoscopic thoracoscopy was less than that of conventional thoracotomy group (P ＜ 0.05). In the conventional thoracotomy group, one patient had secondary thoracotomy (1.8%). There were no deaths, perivalvular leakage, infective endocarditis, or pulmonary complications in one year of follow-up in both groups. Conclusion The double-hole total thoracoscopic approach for mitral value replacement is safe and feasible.
