Echocardiography revealed eccentric hypertrophy with reduced left ventricular ejection fraction (LVEF) and atrial fibrillation with a heart rate of 70\u2013100\u2005b.p.m. Cardiac magnetic resonance imaging, endomyocardial biopsy, and cardiomyopathy lab revealed no cause of HF. High-output HF based on right heart catheterization due to the arteriovenous shunt or related to irregularity due to atrial fibrillation were potential causes. As a result of his malfunctioning gastrointestinal system, the pharmacological options were limited. He was treated with captopril sublingual, initially 6.25\u2005mg three times daily (TID) and later 12.5\u2005mg TID, which reduced blood pressure. Electrical cardioversion to sinus rhythm was successful but did not improve LVEF. Therefore, the patient was opted for surgically reducing the blood flow through the shunt, resulting in normalization of LVEF.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>High-output HF is an uncommon form of HF with an uncertain prevalence. The most common aetiologies reported in the literature are obesity, cirrhosis, and arteriovenous shunts. Sublingual administration of captopril can be an effective treatment option for HF patients unable to absorb oral-administered drugs.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytad360","type":"journal-article","created":{"date-parts":[[2023,7,27]],"date-time":"2023-07-27T20:05:55Z","timestamp":1690488355000},"source":"Crossref","is-referenced-by-count":0,"title":["A case report of high-output heart failure due to arteriovenous shunt without bowel: how to address?"],"prefix":"10.1093","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0369-7670","authenticated-orcid":false,"given":"Zarina","family":"Habibi","sequence":"first","affiliation":[{"name":"Department of Cardiology, Maastricht University Medical Center , p. debeyelaan 25, 6229 HX, Maastricht , The Netherlands"},{"name":"Department of Physiology, University Maastricht , P.O.
