Physical examination was remarkable for jugular venous distention, bilateral lower extremity edema, and a right abdominal pulsatile mass with audible bruit. Transthoracic echocardiogram revealed a left ventricular ejection fraction (LVEF) of 30%\u201335% and a severely dilated inferior vena cava (IVC) with turbulent flow. Computed tomography venography of the abdomen revealed a fistula between the IVC and right renal artery, with aneurysm of the IVC measuring 8\u00a0cm. Cardiac catheterization confirmed a high cardiac output of 12\u00a0l\/min. The patient underwent endovascular repair of the fistula with the use of an Amplatzer septal occluder, and subsequent improvement in symptoms and LVEF. This case highlights a unique etiology of high output heart failure, treated successfully by novel endovascular means.<\/jats:p>","DOI":"10.1093\/omcr\/omag113","type":"journal-article","created":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T13:53:24Z","timestamp":1783518804000},"source":"Crossref","is-referenced-by-count":0,"title":["High
