Advances on Diagnosis,Pathophysiological Characteristics,Predictor and Treatment Strategies of Right Heart Failure Post-Left Ventricular Assist Device Implantation
Right heart failure(RHF)is one of the frequent complications following left ventricular assist device(LVAD)surgery,adversely affecting perioperative hemodynamic stability and contributing to an increased risk of postoperative mortality.The identification of high-risk factors for RHF and the establishment of optimal treatment protocols are crucial for ensuring favorable outcomes.However,the complexity of post-LVAD hemodynamic alterations and the multifactorial mechanisms of RHF present significant challenges in prediction and preventive management.Currently,the clinical guidelines for the treatment of RHF after LVAD surgery are unclear,and critically ill patients often exhibit poor responses to pharmacological treatments,necessitating reliance on right heart mechanical support.This article synthesizes existing literature to comprehensively outline the diagnostic criteria,pathophysiological features,risk prediction indicators,and treatment strategies for RHF following LVAD surgery.It aims to guide the optimization of treatment strategies for RHF post-LVAD and offers new perspectives for improving patient outcomes.
