Sponsor's own description

Portal flow pulsatility detected by Doppler ultrasound is an echographic marker of cardiogenic portal hypertension from right ventricular failure and is associated with adverse outcomes based on previous studies performed at the Montreal Heart Institute. This multicenter prospective cohort study aims to determine if portal flow pulsatility after cardiopulmonary bypass separation is associated with a longer requirement of life support after cardiac surgery.
