A case of a large leiomyomatous uterus with multiple arteriovenous malformations and subsequent high cardiac output state with severe four chamber cardiac enlargement.

Uterine arteriovenous malformations (AVMs) are rare and potentially life-threatening. They can be congenital or acquired. Uterine artery embolization or hysterectomy are considered mainstays of management. AVMs can be associated with leiomyomas, and patients may require both procedures. We present a case of a 42-year-old woman with a massively enlarged leiomyomatous uterus supplied and drained by multiple large AVMs, leading to high cardiac output state with severe four chamber cardiac dilation. Management required a multidisciplinary team of interventional radiology, gynecologic oncology surgery, vascular surgery, cardiac anesthesiology, cardiology, and urology and a 2-day interventional approach of preoperative arterial embolization followed by hysterectomy.
