*4.2.3 Definitions and data collection*

Early and mid-term complications, as well as morbidity and mortality data, were summarized according to recommendations for reporting outcomes after cardiac valve interventions [39]. Early mortality was defined as in-hospital and 30-day mortality; late mortality was defined as death occurring beyond this period. Early graft dysfunction was defined as any homograft regurgitation with a vena contracta more than 0,7 cm due to central jet or periannular leak.
