Improved heart failure after closure of arteriovenous fistula

Abstract

The population of patients with end‐stage renal disease is rapidly growing and hemodialysis remains the most common treatment option. We present a case of a young patient with arteriovenous fistula (AVF)‐related heart failure, and a review of the main hemodynamic changes after AVF formation and ligation procedures.

An arteriovenous fistula in the right kidney as a cause of right ventricular heart failure

“…The presented case shows that heart failure may be caused by an arteriovenous fistula, whose detection is possible during a detailed physical examination (abdominal murmur) and abdominal ultrasound. An arteriovenous fistula should be considered as a cause of high-output right ventricular failure, not only in patients undergoing hemodialysis [1] but also in those with an unclear cause of right ventricular failure [2], especially when echocardiography reveals high TRPG resulting from volume overload accompanied by prolonged PA-AcT due to a low transpulmonary pressure gradient. Endovascular closure of the arteriovenous fistula resolved the heart failure in this patient [3,4].…”
