    Abstract:
    A prospective 'analysis of operative risk and results in video-assisted mitral valve surgery performed in a non selected population is reported. Seventy two consecutive patients (1997-2004) with mean age 60 +/- 12 years underwent a video-assisted mitral valve procedure using a femoral CPB. A transthoracic direct aortic clamping was done in 28 patients (TT) and an endo-aortic occlusion balloon was used in 44 patients (Endo). The surgical approach was a right lateral minithoracotomy in all cases; 16 patients had a previous cardiac surgery. The expected mitral operation (39 repairs, 33 replacements) was done in all cases, without conversion. There were 4 early deaths (1 st month), all in Endo group: 1 aortic dissection, 1 heart failure and 2 sudden deaths. Postoperative complication occurred in 17 patients with 5 reoperations for hemostasis of the thoracic wall. Cumulative rate of mortality and morbidity was 29% in Endo and 28% in TT (ns). Hospital stay was 8 +/- 2 days. At discharge, 4 patients had a residual grade 2 echocardiographic mitral regurgitation after valve repair. In January 2005, with a 1.8 years follow-up, there were 4 late deaths, 3 patients underwent a valve reoperation, 2 patients were still in NYHA class 3 and 5 patients had a residual grade 1 or 2 mitral regurgitation. The 3-year actuarial survival was 86 +/- 10% and the 3-year probability to be free of reoperation was 95 +/- 6%. In mitral valve surgery, video-assisted approach is reliable, the operative risk is controlled and midterm results are not compromised. Video-assisted mitral valve surgery is a new less invasive standard; it is the procedure of choice in valve replacement, in reoperation and in non complex valve repair with good cosmetic results.
