Abstract

Patients with hypertrophic cardiomyopathy (HCM) often have atrial fibrillation, and empiric anticoagulation is recommended in these patients, regardless of other risk factors. However, anticoagulation is not recommended for patients who require hemodialysis (HD) because of the high bleeding risk. We herein report a case of left atrial appendage closure (LAAC) using the Watchman FLX system for a dilated phase HCM patient complicated by persistent atrial fibrillation and requiring HD. LAAC with the Watchman FLX system may be an alternative to antithrombotic medications in patients with dilated HCM complicated by atrial fibrillation and requiring HD.

Keywords: hemodialysis; hypertrophic cardiomyopathy; left atrial appendage closure.
