Management of complications in long-term LVAD support.

INTRODUCTION

Management of complications in long-term LVAD support like aortic regurgitation, progressive decline of right ventricular function, or pump thrombosis are challenging.

METHODS AND

RESULTS

After 2.5 years on a HeartMate II left ventricular assist device (LVAD) a 59-year-old patient was admitted to hospital due to severe hemolysis caused by a partial occlusion and thrombosis caused by a shift of the LVAD inflow cannula towards the lateral wall of the left ventricle (LV). Preoperative assessment revealed additional severe aortic regurgitation and impaired right ventricular (RV) function (severe tricuspid regurgitation, RV ejection fraction 25%, central venous pressure 14 mmHg). After LVAD device exchange and aortic valve replacement (AVR) RV failure occurred and a temporary right ventricular assist device (RVAD) was employed. RVAD explantation was feasible 21 days after surgery. The patient was discharged to a rehabilitation center.

DISCUSSION: In this case, LVAD exchange with concomitant AVR and temporary RVAD efforts saved the patient's life and restored a good quality of life.
