title: Gastrointestinal Symptoms from Left-Ventricular Assist Device External Compression of the Gastric Lumen.
abstract: A 74-year-old man with a left-ventricular assist device (LVAD) as destination therapy for end-stage ischemic cardiomyopathy presented with acute upper gastrointestinal bleeding. Other symptoms included chronic early satiety, intermittent nausea, and non-specific abdominal discomfort since LVAD implantation 3 years ago. An actively bleeding duodenal arteriovenous malformation was successfully treated with endoscopic coagulation. There was also evidence of moderate external compression of the anterior gastric wall from the LVAD pump with luminal narrowing in the antrum. While bleeding may be the most commonly encountered gastrointestinal manifestation in LVAD patients, other potential complications, including luminal compression by the device, should be recognized.
