Efficacy of biventricular pacing for dialysis-related hypotension due to idiopathic dilated cardiomyopathy

A 45-year-old man who had been undergoing maintenance hemodialysis for end-stage renal failure, caused by chronic glomerulonephritis 4 years before, was admitted to our hospital for biventricular pacemaker implantation (BVP). Ten years ago, he was diagnosed with idiopathic dilated cardiomyopathy, an...

Description
Summary:A 45-year-old man who had been undergoing maintenance hemodialysis for end-stage renal failure, caused by chronic glomerulonephritis 4 years before, was admitted to our hospital for biventricular pacemaker implantation (BVP). Ten years ago, he was diagnosed with idiopathic dilated cardiomyopathy, and had been suffering from dialysis-related hypotension (DRH) due to low cardiac function over the past year. An electrocardiogram revealed complete left bundle branch block with a QRS duration of 180 ms, and echocardiography showed moderate hypokinesis of the left ventricular wall and systolic asynchronized motion of the septum and free wall. After BVP, the left ventricular ejection fraction had increased from 29% to 40%, and the transmitral rapid left ventricular filling (E wave) and atrial contraction (A wave) ratio (E/A) had improved from 1.3 to 1.0. Before and after BVP, we measured hemodynamic parameters during hemodialysis by successive echocardiography. Before BVP, systemic vascular resistance had decreased, cardiac output had not changed, and hypotension was noted. In contrast, after BVP, cardiac output had increased and systemic vascular resistance had not changed, which caused an increase in blood pressure. We conclude that BVP improved the cardiac function which resulted in an improvement in dialysis-related hypotension (DRH).
