Cardiac manifestations and clinical management of X-linked Emery-Dreifuss muscular dystrophy: a case series

COMPREHENSIVE CARDIOVASCULAR THERAPY IN EMERY-DREIFUSS MUSCULAR DYSTROPHY: A CASE REPORT

A 25-year-old male with known EDMD was referred for the cardiology consultation due to symptoms of heart failure. Echocardiography showed decrease left ventricular ejection fraction (LVEF) and therapy with ramipril, torsemide and rivaroxaban was initiated. Despite initial improvement, the patient later developed presyncope, bradycardia, irregular heartbeat and worsening of dyspnea. Therefore, implantation of resynchronization pacemaker with the function of implantable cardioverter-defibrillator (CRT-D/P) was performed. Ramipril was substituted by sacubitril/valsartan, and mineralocorticoid receptor antagonist and beta-blocker were initiated. Genetic testing found AD mutation in lamin A/C gene LMNA c.746G>A, p.(Arg249Gln). Upon follow-up, the patient demonstrated resolution of dyspnea and reverse remodeling of the left ventricle with complete restoration of the LVEF.
