Abstract

|
|
|
Hypertrophic cardiomyopathy (H-CM) is a hereditary disorder of the genes that encodes for the proteins of the cardiac sarcomere. The phenotype of H-CM occurs in 1 out of every 500 adults in the general population. Symptoms are variable, including dyspnea, angina, congestive heart failure and syncope. Syncope or sudden cardiac death (SCD) can be caused by ventricular tachyarrhythmia, which could be prevented by implantable cardioverter-defibrillator. Here we present a case of ventricular tachycardia that occurred in a patient with HCM and previous septal myectomy for symptomatic left ventricular outflow obstruction. This case highlights the importance of identification of patients at risk for SCD, and the role of implantable defibrillators for primary prevention of SCD.
