Abstract

BACKGROUND The aim of this study was to investigate the safety, feasibility, and clinical effectiveness of thoracoscopy-assisted mitral valve replacement via thoracic right-anterior minimal incision. MATERIAL AND METHODS A retrospective analysis was conducted of 225 patients with mitral valve lesions who were treated in our hospital from August 2012 to August 2015. Group A included 105 patients undergoing thoracoscopy-assisted mitral valve replacement via a thoracic right-anterior minimal incision, and group B included 120 patients undergoing conventional mitral valve replacement. We collected and analyzed clinical data from both groups. RESULTS The procedures were successful in patients of both groups. No severe complications or mortality were reported. Postoperative mechanical ventilation time (8.6±2.4 h vs. 12.4±3.2 h), duration of intensive care (1.7±1.2 d vs. 2.8±1.3 d), duration of postoperative analgesia use (28.7±8.9 h vs. 36.3±7.5 h), postoperative length of hospital stay (8.2±2.2 d vs. 12.8±2.1 d), pleural fluid drainage (210.5±60.5 ml vs. 425.4±75.6 ml), blood transfusion amount (420.5±80.4 ml vs. 658.3±96.7 ml), and operative incision length (4.7±1.1 cm vs. 22.4±2.5 cm) were significantly shorter (or lower) in group A than in group B. There were different advantages and disadvantages in the 2 kinds of operative procedure in terms of postoperative complications. CONCLUSIONS Thoracoscopy-assisted mitral valve replacement via thoracic right-anterior minimal incision has the same clinical efficacy, safety, and feasibility as conventional mitral valve replacement.
