Sumario:Iatrogenic aortocaval fistula (ACF) is an infrequent cause of heart failure. A 65-year-old man presented to the cardiology clinic eight months after an open abdominal aortic aneurysm (AAA) repair. He developed predominantly right-sided cardiac failure after surgery, with minimal response to guideline-directed medical therapy. A transthoracic echocardiogram revealed decreased right-sided systolic function. A computed tomography angiographic scan of the abdomen revealed a large ACF at the distal end of the AAA repair. The patient was referred for closure surgery. ACF should be considered in a patient with unexplained right heart failure, especially in the setting of a known AAA or recent AAA repair.
