Acute fistula occlusion may lower output in high-flow dialysis patients but risks worsening LV failure; leaves open whether chronic closure alters HF outcomes.
Does acute digital occlusion of arteriovenous fistulas alter cardiac output and left ventricular performance in uremic patients on regular hemodialysis?
Acute A-V fistula occlusion effectively lowers cardiac output, which may be beneficial in high output failure but can worsen hemodynamics in patients with intrinsic left ventricular disease.
