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.
