Liver Infusion Flow Evaluation With ultraSound for Assessment of Right Ventricular Function: a Single cEnter Cohort Study (LIFESAVE)
Right ventricular dysfunction (RVD) after cardiac surgery is associated with ischemia and myocardial injury. While echocardiographic measures like Tricuspid Annular Plane Systolic Excursion (TAPSE) are frequently used to assess ventricular function, they have limitations in terms of accuracy. The pulmonary artery catheter remains the gold standard for assessing RVD. This dysfunction is associated with an increased risk of both renal and hepatic failure, complications that significantly affect patient outcomes. Doppler ultrasound has emerged as a valuable tool in predicting these complications, particularly in monitoring portal circulation and hepatic perfusion. This study aims to explore the association between portal flow pulsatility and RVD after cardiac surgery.
