Abstract

Hypertrophic cardiomyopathy (HCM) is an extremely heterogeneous genetic disease that affects the left ventricle (LV) and has a varied clinical course and phenotypic expression. Here, we report a case of two sisters with HCM who developed a massive refractory left atrial appendage (LAA) thrombus and recurrent embolism. The older sister, who was at a high surgical risk due to progressive LV systolic dysfunction with an ejection fraction of 19%, underwent LAA plication in combination with implantation of an LV assist device after progression to treatment-refractory heart failure at the age of 49. The younger sister underwent surgical thrombectomy, LAA plication, and Maze surgery before deterioration of heart failure at the age of 47. She was free from embolism and atrial fibrillation for 2years after surgery. Individualized therapeutic approaches targeting the LAA at a relatively early stage are required in the subgroups of HCM patients with left atrial dysfunction.
