Brief summary
All patients undergoing elective aortic valve replacement for stenotic aortic valve replacement or aortic valve regurgitation at our institution from 2012 to 2021 who met the inclusion criteria for the study (described in the dedicated session) will be enrolled in the study. These patients will be contacted to provide information about the clinical status, NYHA functional class, possible rehospitalization, possible cardiovascular events and to perform a postoperative echocardiography if not performed in the previous year. Once consent is given, pre-, intra- and post-operative data will be collected in a dedicated, structured, database.

Interventions
PROCEDUREAortic valve replacement
All operations were performed through median longitudinal sternotomy or mini-sternotomy. 8 Intraoperative transesophageal echocardiography (TOE) was used in all patients. Arterial cannulation was central and venous cannulation was achieved with a common two-stage cannula in the right atrium. Left ventricle was vented through the right superior pulmonary vein. In minimally invasive procedures, venous cannulation was achieved percutaneously. Myocardial protection was achieved by administration of cold crystalloid or blood cardioplegia at the surgeon's discretion in an antegrade (indirect or selective) or retrograde fashion. The removal of the calcified cusps and the decalcification of the annulus was performed according to traditional techniques. All the prosthesis were be implanted with supranular technique and 2-0 U-shaped pledgeted sutures.
