High-output cardiac failure is a less prevalent form of heart failure. Most patients with heart failure are typically categorized as having either systolic or diastolic dysfunction with elevated systemic vascular resistance. Individuals with high-output cardiac failure exhibit normal cardiac function and decreased systemic vascular resistance.

Ilio-iliac arteriovenous fistula is an unusual complication of aorto-iliac aneurysms that can occur spontaneously, traumatically or iatrogenically. The typical clinical presentation includes the characteristic triad of high-output heart failure, a pulsatile abdominal mass with unilateral limb ischemia, or signs of venous congestion. We describe a rare case of spontaneous rupture of an aortoiliac aneurysm into the left common iliac vein of a 65-year-old man, easily diagnosed by angiography.

Pulmonary hypertension is a disease process affecting pulmonary circulation and is defined by an increase in pulmonary artery pressure subsequently causing right ventricular failure. Vascular complications, including arteriovenous (AV) fistula, are recognized, but are uncommon complications of spinal surgery. AV fistula increases venous return to the right heart and can promote a volume overload related high-output cardiac state, pulmonary hypertension, and right heart failure.

A minority of patients with heart failure present in a high-output state. We described an uncommon case of high-output heart failure caused by an iliac arteriovenous fistula (IAVF), a rare but serious complication after lumbar discectomy surgery (LDS). A 44-year-old man with no notable medical condition except a history of herniated nucleus pulposus necessitating the L4-L5 LDS 5 years ago presented with clinical signs of progressive high-output heart failure.

A 35-year-old female presented to our emergency department with clinical signs of acute heart failure. Clinical workup identified severe right heart (RH) dilation and dysfunction with a crossing membrane structure in the right atrium. Right heart catheterization confirmed high output heart failure (HOHF), pulmonary hypertension (PH), and left-to-right blood shunting followed by the documentation of multiple liver and pulmonary arteriovenous malformations (AVMs).
