OBJECTIVE: The objective of our study was to review the results for thoracoscopic mitral valve repair in our center since the program began.
METHODS: The study cohort consists of 516 consecutive patients underwent thoracoscopic mitral valve repair at our center from February 2012 to September 2016. The mean age was 45.02±16.44 years and 239 patients(46.31%) were female. The mean left ventricular ejection fraction was 66.68±6.74%.
RESULTS: The procedure was successfully performed using a right lateral mini-thoracotomy and femoral cannulation for cardiopulmonary bypass in 487 patients, unfortunately 29 patient(5.62%) required intraoperative conversion to full sternotomy. Mitral valve repair techniques consisted of ring annuloplasty with or without chordae-replacement or leaflet resection. Concomitant procedures included atrial fibrillation ablation in 33 patients(6.40%), patent foramen ovale/atrial septal defect closure in 105 patients(20.35%) and atrial myxoma removal in 3 patients. Mean duration of CPB was 147.60±45.38 min and mean aortic cross-clamp time was 96.22±32.51 min. Thirty-day mortality was 0.39% and all important postoperative adverse events morbidity was 21.32%.
CONCLUSIONS: Our study shows that the thoracoscopic mitral valve repair, whether with or without concomitant procedures, can be performed in the vast majority of patients, with low perioperative complication rates.
