Objective To compare video-assisted thoracic surgical technique (VATS) and conventional surgical technique (CSM) in mitral valve replacement (MVR). Methods We retrospectively analyzed clinical data of 93 patients in our hospital with mitral valve replacement between January 2010 and January 2015. The patients were divided into two groups including a VATS group and a CSM group.There were 43 patients with 25 males and 18 females at age of 57.43±5.65 years in the VATS group, and 50 patients with 27 males and 23 females at age of 56.40±6.32 years in the CSM group.The clinical outcomes of the two groups were compared. Results There was no mortality. Echocardiography was normal in both groups during 1-year follow-up. There was no significant difference between the two groups in the operative time, aortic clamping time, cardiopulmonary bypass (CPB) time, or ventilation time. As compared with the CSM group, the patients in the VATS group had a significantly lower complication rate, shorter chest incision length (5.23±1.36 cm vs. 18.21±3.89 cm), less blood transfusion (1.75±0.25 U vs. 3.15±1.50 U), less chest drainage (202.34±12.12 ml vs. 412.32±21.56 ml) and lower pain score (1.26±0.86 vs. 3.01±1.13), shorter time of postoperative hospital stay (8.20±2.36 d vs. 12.10±3.26 d). Conclusion MVR under VATS is not only technically feasible, but also with excellent clinical results.
ObjectiveTo evaluate outcomes of mitral valvuloplasty with artificial chord and mitral annuloplasty ring in patients with mitral valve prolapse. MethodsFrom January 2012 to March 2014, mitral valvuloplasty with artificial chord and mitral annuloplasty ring were performed for 58 patients with mitral valve prolapsed in Department of Cardiovascular Surgery, Fujian Provincial Hospital, among which 47 simple anterior or posterior mitral valvuloplasty and 11 combined anterior-posterior mitral valvuloplasty were completed. There were 33 males and 25 females aged (53.7±14.3) years. ResultsThere was no in-hospital death. Three patients received mitral valve replacement. The transoesophageal echocardiography found no or trivial mitral regurgitation in 48 patients, mild mitral regurgitation in 7 patients. The diameter of the left atrium (LA) and left ventricle (LV), left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV) were significantly decreased after the operation. During the follow-up of 6 months to 2 years, the cardiac function of the patients improved. ConclusionMitral valvuloplasty with artificial chord and mitral annuloplasty ring is simple, reliable and effective treatment for patients with mitral valve prolapse, and its shortand mid-term outcome is good.
