I need descriptive statistics to be conducted using Microsoft Excel.-Multicenter retrospective study -There will be 2 groups: With proctoring (one assistant operating and Emmanuel assisting/leading) vs. without proctoring (Emmanuel operating). -For each group, there will be 3 subgroups to compare the 2 groups. The idea is to have 2 groups: With Proctoring (Surgery performed by the assistant) vs Without Proctoring (Surgery performed entirely by the referring surgeon) Population characteristics: history, age, sex, BMI, center, ultrasound characteristics, etc. The primary endpoint was postoperative morbidity and mortality. Outcomes: duration of CEC, duration of clamping, failed plasty, leakage at discharge, reintervention, mortality at 1M 6M 1A... -Primary outcome was a composite criterion of mortality (30 days and 1 year), reoperation, aortic valve leak >2, aortic valve leak >3. -Secondary outcomes included: CEC time, clamping time, perioperative major bleeding. -Population characteristics: the 2 groups should be comparable. Criteria: Age, sex, BMI, history, ultrasound criteria, valve type (tricuspid, bicuspid, unicuspid)... Thank you !
