Conditions

Aortic bioprothesis implanted patient for valvular heart disease

Brief summary

The primary endpoint is a composite efficacy endpoint including death, myocardial infarction, stroke, systemic embolism, deep vein thrombosis, or pulmonary embolism and valve thrombosis. The primary endpoint will be evaluated at the end of the treatment (105±15 days after inclusion and randomization).

Detailed description

Bleeding (primary safety endpoint) : ISTH major bleeding, Bleeding with ISTH bleeding scale : o ISTH major bleeding o ISTH non-major clinically relevant bleeding, Bleeding with the TIMI bleeding scale : o TIMI major bleeding o TIMI minor bleeding, Bleeding with the BARC definition (BARC 3 to 5), Composite efficacy endpoints including: All-cause death, Myocardial infarction (Fourth Universal Definition of Myocardial Infarction), Stroke, Systemic embolism, Deep vein thrombosis, Pulmonary embolism, Valve thrombosis, All-cause death, Aortic valve thrombosis (adapted from VARC-3 definition), Mean aortic gradient (mmHg) and peak velocity (m/s)
