obstructive cardiomyopathy

Contraindications are severe obstructive cardiomyopathy, hypovolemia, tachycardia, and ventricular aneurysm.

Obstructive cardiomyopathy and other pathologic findings involving the cardiovascular system may be a cause of death in those whose cardiac deformities are profound.

This phenomenon can be a sign of hypertrophic obstructive cardiomyopathy or of many other types of heart disease (see list below).

Either alcohol septal ablation or myectomy offers substantial clinical improvement for patients with hypertrophic obstructive cardiomyopathy.

Perhaps the most common abnormality is hypertrophic obstructive cardiomyopathy, a thickening of the muscle that can cause a blockage - and death - when under stress.

Outcome of surgical myectomy after unsuccessful alcohol septal ablation for the treatment of patients with hypertrophic obstructive cardiomyopathy.

One study found the Valsalva maneuver to have a sensitivity of 65%, specificity of 96% in detecting hypertrophic obstructive cardiomyopathy (HOCM).

The murmur increases with squatting, decreases with standing and isometric muscular contraction, which helps distinguish it from hypertrophic obstructive cardiomyopathy (HOCM).

Classically, it is detected when aortic insufficiency exists in association with aortic stenosis, but may also be found in isolated but severe aortic insufficiency, and hypertrophic obstructive cardiomyopathy.

In a large subset of patients with hypertrophic obstructive cardiomyopathy, thickening of the heart muscle in a particular part of the interventricular septum causes obstruction to blood being ejected from the left ventricle.

In 1994 he introduced percutaneous alcohol septal ablation (ASA, TASH, PTSMA), a non-surgical method for the treatment of hypertrophic obstructive cardiomyopathy, which often allows symptomatic patients to avoid open heart surgery.
