Abstract：Right heart failure following left ventricular assist device(LVAD)implantation is one of the key complications determining prognosis.With the gradual popularization of the third-generation magnetic levitation continuous-flow devices in China,preoperative ultrasound-based risk prediction of right heart failure and postoperative bedside ultrasound-centered real-time monitoring have become feasible approaches to reduce the incidence and mortality of right heart failure.Based on sorting out the application pattern and population characteristics of LVAD in China,this paper systematically summarizes the latest definition and classification of right heart failure,concludes the preoperative ultrasound predictors with good repeatability and accuracy,proposes the ultrasound sequence and follow-up time points for postoperative follow-up,and constructs an ultrasound-driven intervention decision-making process.The aim is to provide a set of diagnosis and treatment framework and follow-up reference for the multidisciplinary treatment team.
