Background: Minimally invasive cardiac surgery of the mitral valve (MICS-MV) has become the routine approach to mitral valve disease in some centers. We reported early results of 51 cases of MICS-MV.
Method: The preoperative variables, intraoperative date and postoperative outcomes of patients undergoing MICS-MV and conventional surgery of the mitral valve were collected from January 2013 to August 2014.
Results: Aortic cross clamp and cardio-pulmonary bypass( CPB) time were longer in this series than in the conventional median sternotomy. We experienced complications and 2 patients required mitral valve replacement (MVR) due to failure of repair in initial MICS cases. One case of the patients with infective endocarditis was performed conversion of from MICS to a median sternotomy due to left ventricle(LV) rupture.
Conclusion: The early-time outcomes in these patients are acceptable. We think that large number of MICS-MV operations are required to overcome the learning curve.
