Successful HeartMate 3 implantation in isolated right heart failure—first in man experience of right heart configuration

In this article, we present the case of a 72-year-old male patient suffering from a severe form of singular isolated end-stage right heart failure based on arrhythmogenic right ventricular cardiomyopathy (ARVC), who was admitted to our clinic for acute cardiac decompensation. Echocardiography result revealed a dilated right atrium and ventricle (right ventricular end diastolic diameter, RVEDD: 59 mm) with a moderate tricuspid regurgitation owing to a dilated valve annulus of 48 mm. The left heart showed no pathological impairment: left ventricular end diastolic diameter (LVEDD) was 40 mm with a left ventricular ejection fraction (LVEF) of 50–55%. The patient also showed a progressive impairment of liver function by means of elevated levels of liver enzymes. Pulmonary artery embolism was excluded by computer tomography
