Systemic organ condition should be considered before implantation of left ventricular assist device (LVAD) as a bridge to cardiac transplantation. It is, nevertheless, difficult to evaluate the reversibility of organ function such as kidney and liver which are directly affected by hemodynamics. We experienced a 44-year old woman with autosomal dominant polycystic kidney disease who was also diagnosed with dilated cardiomyopathy. She also had moderately impaired renal function (serum creatinine level: 1.8 mg/dL). We calculated kidney prognosis before LVAD implantation, and estimated that there would be more than ten years for functional terminus of kidney using total kidney volume (433 mL/m). We further estimated the presence of prerenal factors affecting her kidney condition, which would be recovered after LVAD implantation. Indeed, her renal function was significantly improved after LVAD implantation (serum creatinine level: 1.0 mg/dL). In this presentation, we will demonstrate pre-/post-LVAD-implantation treatment strategy for a dilated cardiomyopathy patient concomitant with organic kidney disease.
