Long-term Effects of Arteriovenous Fistula Closure on Echocardiographic Functional and Structural Findings in Hemodialysis Patients: A Prospective Study

Closure of an AVF determines a significant decrease in LV internal diastolic diameter, interventricular septum thickness, and diastolic posterior wall thickness. This is associated with significant improvement in LVEF, a significant decrease in LVM and LVMi, and a more favorable shift of cardiac geometry toward normality.
