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.

Inclusion Criteria:

• Patients > 18 y-o who underwent aortic valve replacement

Exclusion Criteria:

• None

All patient operated for aortic valve replacement with or without associated cardiac surgery from 2009 in Dijon University Hospital

All patients signed a institutional form prior to the procedure stating that they did not object to the use of their medical data for research purposes. Before inclusion, all patients (or a trusted person) were informed about the study and its objectives. No opposition was expressed.
