Factors Influencing Morbi-mortality in Right Anterior Minithoracotomy Approch for Aortic Valve Replacement Operated at Dijon University Hospital

Since 2009, positive experiences with right anterior minithoracotomy as an approach to aortic valve replacement are extensively practiced in our institution. The primary disease process for which patients are referred remains aortic stenosis. But more and more, we met older patients with both aortic stenosis and other cardiac pathology (coronary artery disease, other valvulopathy...). Even if minimally invasive valve surgery has been demonstrated to significantly improve postoperative course (reduced blood transfusion, pain, hospital lengths of stay) and to enhance postoperative recovery, when compared with a median sternotomy, it is however important to have medical data and statistics in order to better understand the factors influencing morbi-mortality and thereby to continue this improvement.
