Abstract
BACKGROUND: Although there are reports of recovery of cardiac function after renal transplantation, the feasibility of renal transplantation in patients with low cardiac function remains controversial. CASE PRESENTATION: A 59-year-old Japanese male was scheduled to undergo living-donor renal transplantation (LDRT) under general anesthesia. Preoperative transthoracic echocardiography revealed severe mitral regurgitation (MR) and a left ventricular ejection fraction (LVEF) at 30%. LDRT was conducted prior to cardiac surgery with restrictive fluid management and close monitoring of cardiac function. The patient's renal function improved promptly after the LDRT, and his hemodynamics were stable throughout the perioperative period. Along with improvements in the patient's renal function and anemia, the patient's cardiac function improved to LVEF 50% and achieved drastically improved MR as well as cardiac function, without intervention. CONCLUSION: This case indicates that LDRT has the potential to improve cardiac function in patients who have been on hemodialysis for more than 20 years.
