Abstract
The management of right heart failure during durable left ventricular assist device (LVAD) support remains an unsolved issue so far. We had a 44-year-old male patient who was diagnosed with arrhythmogenic right ventricular cardiomyopathy and received HeartMate 3 LVAD (Abbott, USA) implantation as a bridge-to-transplant indication. The pump speed was adjusted as low as 4500 rpm to avoid the left ventricular narrowing and interventricular septal leftward shift. Riociguat was administered to decrease the afterload of the right ventricle and increase the preload of the left ventricle, in addition to the combination of neurohormonal blockers. Frequent low-flow alarm events eventually disappeared after amlodipine administration, and he was successfully returned to work. We here present a unique management in a patient with right heart failure due to arrhythmogenic right ventricular cardiomyopathy during HeartMate 3 LVAD support.
期刊介绍：
The aim of the Journal of Artificial Organs is to introduce to colleagues worldwide a broad spectrum of important new achievements in the field of artificial organs, ranging from fundamental research to clinical applications. The scope of the Journal of Artificial Organs encompasses but is not restricted to blood purification, cardiovascular intervention, biomaterials, and artificial metabolic organs. Additionally, the journal will cover technical and industrial innovations. Membership in the Japanese Society for Artificial Organs is not a prerequisite for submission.
