BACKGROUND: Gastrointestinal (GI) bleeding is one of the recently reported complications with continuous flow left ventricular assist devices (LVAD). The pathophysiology and etiology are unclear. We sought to describe the relationship between aortic valve movements and GI bleeding among patients with a new generation of LVAD. METHODS: We evaluated the data of 30 patients who underwent LVAD (HeartWare VAD) implantation from December 2010 to September 2012. The most common etiologic diagnosis was dilated cardiomyopathy. Patients were considered to show GI bleeding if they had hematemesis, melena, or hematochezia. RESULTS: Among 3 patients, 2 displayed upper GI bleeding and 1 had lower GI bleeding based on endoscopic and colononoscopic examinations. Pathological reports showed arteriovenous malformations in patients diagnosed with upper GI bleeding. The absence of aortic valve movements and a history of previous GI bleeding were significant risk factors (P = .021 and P = .007, respectively). CONCLUSION: In addition to aortic valve movements, we believe that a GI bleeding history was an equally important factor predisposing to this complication.
