Does hypertrophic cardiomyopathy require surgery?

Does hypertrophic cardiomyopathy require surgery?

Septal myectomy is a type of open-heart surgery for hypertrophic cardiomyopathy (thick heart muscle). It decreases symptoms of the condition. A muscular wall called the septum separates the left and right ventricles, the 2 lower chambers of the heart.

How is myectomy used to treat hypertrophic cardiomyopathy?

From studies conducted at our Centre and from international multicenter studies, myectomy in subjects with obstructive hypertrophic cardiomyopathy has proven very effective in improving symptoms such as breathlessness (dyspnea), chest pain (angina), pre-lipotimias and syncopes.

What are the symptoms of hypertrophic cardiomyopathy?

Hypertrophic cardiomyopathy is a genetic disorder characterized by marked hypertrophy of the myocardium. It is frequently accompanied by dynamic left ventricular outflow tract obstruction and symptoms of dyspnea, angina, and syncope.

How does hypertrophic cardiomyopathy affect the mitral valve?

Hypertrophic obstructive cardiomyopathy (HOCM) is a disease that causes thickening of the heart muscle. When the muscular septum that divides the right and left side of the heart becomes too think, it begins to block the flow of blood out of the heart to the body, and may cause the mitral valve to leak (regurgitation).

When to have a septal myectomy for HOCM?

It is a common cause of sudden unexplained death, especially in young people. The operation for HOCM is called septal myectomy. Septal myectomy is performed in patients who have symptoms despite medical therapy, or if the obstruction severely restricts blood ejection from the heart.

Can a septal myectomy be used to treat hypertrophic cardiomyopathy?

In many patients, the hemodynamic and clinical results are comparable to that of septal myectomy. However, the results of alcohol septal ablation are dependent on the septal perforator artery supplying the area of the contact between the hypertrophied septum and the anterior leaflet of the mitral valve.

Which is the best treatment for hypertrophic cardiomyopathy?

Surgical therapy – myectomy – is considered by the guidelines to be the best treatment for obstructive hypertrophic cardiomyopathy. Surgical therapy – myectomy – is considered by the guidelines to be the best treatment for obstructive hypertrophic cardiomyopathy. Skip to content Hypertrophic Cardiomyopathy

When to see a cardiomyopathy specialist for HCM?

Patients with a diagnosis of hypertrophic cardiomyopathy should be assessed at an experienced center to determine the severity of their condition and to develop a treatment plan. It is estimated that obstruction occurs in more than 70 percent of patients with HCM.

Why does the septum thicken in hypertrophic cardiomyopathy?

In hypertrophic cardiomyopathy, the walls of the ventricles and septum may thicken abnormally. The septum may bulge into the left ventricle and partially block the blood flow out to the body. This causes the heart to work harder.
