OBJECTIVE: To summarize the clinical experience of 60 patients underwent three- dimensional video assisted thoracoscopic mitral valvuloplasty.
METHODS: Sixty patients were enrolled retrospectivly from March 2014 to January 2016 in Department of Canliacvascular Surgery, Guangdong Cardiovascular Institute. They underwent three-dimensional video assisted thoracoscopic mitral valvuloplasty. There were 37 and 23 female patients. The range of age was 15 to 78 years ( the median age was 47 years) . The techniques of mitral valvulopalsty were chordae tendineae transplantation (53 patients) , annuloplasty (58 patients) , posterior leaf1et resection ( 13 patients) , anterior leaflet resection ( 2 patients) , commissure resection ( 1 patient). Their information from charts were collected. The follow-up time was lasting 3 to 25 months by telephone or outpatient department interview. The data was analyzed via paired t-test or Wilcoxon signed-rank test.
RESULTS: Conversions to mitral valve replacement were performed for two patients. No patients underwent thoracotomy. The operation time was (213 ±37) minutes, cardiopulmonary bypass time was ( 129 ±31) minutes, aortic cross clamping time was (81 ±21) minutes. Postoperative hospital stay was ( 7 ± 3) days. During follow-up period, there were no re-operation and no death. Mitral regurgitation level and New York Heart Association class were both improved (Z = - 6.286, P=0.000, Z = - 6. 237, P= 0. 000) , respectively. Besides, there was also no new atrial fibrillation patients.
CONCLUSIONS: Not only does three-dimensional video assisted thoracoscopic mitral valvuloplasty maintain the advantages of 2- 0imentsional thoracoscopy, but also have the similar view of median thoracotomy. This technique showed promising clinical value in the future.
