Remote Stab Wound Resulting in AV Fistula and High-Output Heart Failure

Abstract EN

A 54-year-old African American male with no medical history presented to an urgent care clinic with signs and symptoms of new-onset congestive heart failure.

There was an initial concern for congestive heart failure secondary to an ischemic etiology as an echocardiogram revealed a depressed ejection fraction.

However, a left heart cardiac catheterization did not demonstrate any significant coronary disease.

As a loud bruit was auscultated over the right base of the patient’s neck, he underwent a carotid duplex ultrasound revealing a fistula between the right common carotid artery (CCA) and the right internal jugular vein (IJV).

A diagnosis of high-output heart failure secondary to a large arteriovenous (AV) fistula was made, and the patient underwent ligation and repair of the fistula with resolution of symptoms of congestive heart failure.
