Hypertrophic Obstructive Cardiomyopathy

Patient Volume

HOCM Patient Volume


Hypertrophic obstructive cardiomyopathy (HOCM) is the thickening of the lower chambers of the heart. The septal muscle, which divides the right and left chambers, is especially affected. The condition can impede blood flow from the heart to the aorta. Cleveland Clinic physicians use a comprehensive approach to diagnose and treat patients with HOCM. This includes a physical exam, electrocardiograph (EKG), chest X-ray, echocardiogram, and magnetic resonance imaging (MRI).
