Abstract

Left ventricular hypertrophy (LVH) is a multifactorial complication frequently seen in patients with advanced chronic kidney disease. An arteriovenous fistula (AVF) is the preferred method for hemodialysis access. Once functional, AVFs demonstrate better patency rates and fewer complications when compared to other forms of vascular access. AVFs have been implicated in cardiac remodeling, but it is controversial whether those changes can be reversed by surgical ligation or blood flow reduction. In this study, we describe a cohort of asymptomatic patients with LVH who underwent AVF banding with a two-dimensional-echocardiogram done before and after the intervention to evaluate the association between AVF surgical banding and left ventricular mass (LVM) changes. Our results show that AVF surgical banding did not alter the left ventricular mass index (LVMI) with a mean prebanding LVMI of 70.3 ± 57.5 g/m2 and mean postbanding LVMI of 81.9 ± 55.9 g/m2, (P = 0.4). Our study shows that AVF flow reduction by surgical banding did not alter LVMI, and therefore LVH, in end-stage renal disease patients who have not yet shown clinical manifestations of cardiac disease.
