Overview

Overview

Hypertrophic cardiomyopathy (HCM) is a complex type of heart disease that affects the heart muscle. HCM causes thickening of the heart muscle (especially the ventricles, or lower heart chambers), left ventricular stiffness, mitral valve changes and cellular changes.

At Cleveland Clinic Florida’s Heart, Vascular & Thoracic Institute, we have a special interest in treating Hypertrophic Cardiomyopathy (HCM). Hypertrophic cardiomyopathy affects an estimated 600,000 to 1.5 million Americans, or one in 500 people. It is more prevalent than multiple sclerosis, which affects one in 700 people.

What We Treat

What We Treat

Cleveland Clinic Florida’s Hypertrophic Cardiomyopathy Center is a multidisciplinary specialty treatment group dedicated to the diagnosis and treatment of HCM in individuals and family members. We bring together clinicians that specialize in HCM, from Cardiovascular Medicine and Cardiothoracic Surgery, with expertise in diagnostic and genetic testing, medical management, and interventional and surgical procedures for patients with obstructive hypertrophic cardiomyopathy.

Procedures

Procedures

Procedures for the treatment of hypertrophic obstructive cardiomyopathy include septal myectomy, ethanol ablation, implantable cardioverter defibrillator (ICD) and heart failure management, as needed.

Septal Myectomy

During this surgical procedure, the surgeon removes a small amount of the thickened septal wall to widen the outflow tract (the path the blood takes) from the left ventricle to the aorta. A Septal Myectomy is considered when medications are not effective in treating HCM. This frequently eliminates mitral valve regurgitation.

Ethanol ablation

This procedure, also called septal ablation, is usually reserved for patients who are not eligible candidates for septal myectomy. The ablation procedure is performed in the cardiac catheterization laboratory. First, the small coronary artery that supplies blood flow to the upper part of the septum is located during a cardiac catheterization procedure. A balloon catheter is inserted into the artery and inflated. A contrast agent is injected to locate the thickened septal wall that narrows the passageway from the left ventricle to the aorta. When the bulge is located, a tiny amount of pure alcohol is injected through the catheter. The alcohol kills the cells on contact, causing the septum to shrink back to a more normal size over the following months, widening the passage for blood flow.

Implantable Cardioverter Defibrillators (ICD)

ICDs are suggested for people at risk for life-threatening arrhythmias or sudden cardiac death. The ICD is a small device placed just under the skin and is connected to wire leads that are threaded through the vein to the heart. An ICD constantly monitors the heart rhythm. When it detects a very fast, abnormal heart rhythm, it delivers energy (a small but powerful shock) to the heart muscle to cause the heart to beat in a normal rhythm again. Your doctor will tell you if an ICD is recommended.
