Short-term left ventricular assist device (LVAD) has been widely applied in patients with end-stage heart failure, effectively improving hemodynamic perfusion and cardiac function. As a bridge to heart transplantation, this technology has rapidly developed. However, recent studies indicate that right heart failure (RHF) represents the most common complication following LVAD implantation, with an incidence rate of 25%-30%. This condition induces right-sided congestive symptoms, leading to deterioration of quality of life, reduced survival rates, and even compromising successful bridging to heart transplantation. Currently, diagnostic criteria and early identification methods for post-LVAD RHF remain under investigation, while echocardiographic parameters and invasive hemodynamic measurements provide comprehensive assessment of right ventricular function. Therefore, this study systematically reviews recent research findings from both domestic and international scholars regarding echocardiographic and hemodynamic predictors of RHF, aiming to identify potential directions for enhancing predictive capabilities of post-LVAD RHF.
