Key result
Occlusion of disused arteriovenous fistulas in CAPD patients significantly improved left ventricular ejection fraction by 14.1% and reduced left ventricular end-diastolic dimension by 4.0% after one year.

Does the occlusion of disused arteriovenous fistulas improve cardiac function in continuous ambulatory peritoneal dialysis patients?
Occlusion of disused arteriovenous fistulas in CAPD patients chronically reduces cardiac preload and improves left ventricular contractility, particularly in those with reduced baseline cardiac function.
May support occlusion of disused AVFs to improve LV function in CAPD; hypothesis-generating and requires randomized confirmation before practice change.

Takamizawa et al. (1994) conducted a cohort in Continuous ambulatory peritoneal dialysis (CAPD) with disused arteriovenous fistula (n=28). Arteriovenous fistula occlusion vs. Retained arteriovenous fistula was evaluated on Change in left ventricular ejection fraction (EF) at 1 year (14.1% increase, p=<0.05). Occlusion of disused arteriovenous fistulas in CAPD patients significantly improved left ventricular ejection fraction by 14.1% and reduced left ventricular end-diastolic dimension by 4.0% after one year.
