    AbstractHypertrophic cardiomyopathy (HCM) patients with atrial fibrillation (AF) are at high risk for stroke. Left atrial appendage closure (LAAC) is a promising alternative for stroke prevention in AF patients. We aimed to review the clinical outcomes of patients with AF and HCM at our center. We reviewed 673 patients who underwent LAAC implantation from 2014 to 2021 in a tertiary center, of whom 15 had HCM. AF Patients with HCM were compared with sex and age matched controls who also underwent LAAC. From 2014 to 2021, 673 AF patients received LAAC in a single center, of whom, 15 patients had HCM. LAAC devices were successfully implanted in 14 HCM patients and 59 patients in the control group. During the follow-up period (median 1151 days range: 132-2457 days), 2 HCM patient had ischemic strokes. There were another 2 HCM patients who had sudden cardiac death (SCD). Compared with the control, HCM patients had higher cumulative rate of combined death and stroke (26.67% vs 3.33%, P = .024). In our initial clinical experience, the cumulative stroke and death rate of the HCM patients was significantly higher than that of the non-HCM patients.Copyright © 2023 the Author(s).
