[Short-term effect of thoracoscopy-assisted mitral valvuloplasty in patients with mitral valve prolapse].

The data of 56 patients with mitral valve prolapse undergoing thoracoscopy-assisted mitral valvuloplasty in the Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University from May 2019 to December 2020 were retrospectively analyzed. Among them, 31 cases were male and 25 cases were female, with a mean age of (45±14) years. There was no death during perioperative period. No patient was converted to median sternotomy. The duration of cardiopulmonary bypass (CPB), aortic cross-clamp and operation was (207±58) min, (134±59) min, and (374±90) min, respectively. The intraoperative blood loss was (690±268) ml, and 5 (8.9%) patients required blood transfusion. Postoperative mechanical ventilation duration was (19±9) h, and 24-hour pleural fluid drainage volume was (460±247) ml. The length of intensive care unit (ICU) and hospital stay was (25±6) h and (13±4) d, respectively. Therefore, thoracoscopy-assisted mitral valvuloplasty has the advantages of reliable curative effect, less trauma, less complications, fast recovery and satisfactory perioperative outcomes.
