Résumé
Background Right ventricular failure after cardiac surgery is associated with morbidity and mortality. Right ventricular dysfunction results in hepatic venous congestion, which impacts the portal circulation. We aimed to determine whether an increased portal flow pulsatility fraction was associated with right ventricular dysfunction in cardiac surgery patients. We also aimed to describe the haemodynamic factors and postoperative complications associated with an increased portal pulsatility in this setting. Methods We conducted a prospective single-centre cohort study, recruiting adults undergoing cardiac surgery. Portal flow was assessed before, during, and after surgery by Doppler ultrasound. A detailed haemodynamic and echocardiographic assessment was performed at the same time points. Results A total of 115 patients were included. Both systolic and diastolic right ventricular dysfunction were associated with a higher portal pulsatility fraction (P=0.008 and
