title: High-Output Heart Failure from a Hepatic Hemangioma With Exertion-Induced Hypoxia.
abstract: Patients with hepatic hemangiomas have been known to have high-output heart failure as a result of left-to-right arteriovenous shunting. We report a patient with a hepatic hemangioma that presented with high-output heart failure with hypoxia on exertion. After embolization of the hemangioma, the patient's hypoxia resolved and ejection fraction improved. In the absence of cardiopulmonary pathophysiology, we presume that our patient's hemangioma was causing a right-to-left shunt as opposed to an expected left-to-right shunt.
