Right ventricular stroke work index is a useful but invasively measured parameter that can be used to predict right heart failure following continuous-flow left ventricular assist device implantation. Right ventricular contraction pressure index is a novel parameter that was developed to measure right ventricular stroke work index with echocardiography. We aimed to investigate the clinical usefulness of right ventricular contraction pressure index to predict short-term mortality and right heart failure in patients who underwent continuous-flow left ventricular assist device implantation. ⋯ Right ventricular contraction pressure index was found as a useful parameter for determining short-term postoperative mortality in patients undergoing continuous-flow left ventricular assist device implantation.

The frequency of using veno-arterial extracorporeal membrane oxygenation increased, especially in patients with refractory cardiogenic shock or cardiac arrest. However, data of complications of veno-arterial extracorporeal membrane oxygenation are lacking. This study sought to investigate the incidence of veno-arterial extracorporeal membrane oxygenation complications for acute myocardial infarction patients with refractory cardiogenic shock or cardiac arrest and its relationship with patient survival. ⋯ Although veno-arterial extracorporeal membrane oxygenation can improve the survival, it is associated with morbidity. Therefore, risk-benefit analysis for veno-arterial extracorporeal membrane oxygenation and prevention of complications are important to improve prognosis.
