ABSTRACT
Hypertrophic obstructive cardiomyopathy is a complex and challenging disease. Medical therapy, surgical therapy, and pacing therapy have been used with some success over the years. Nonsurgical septal reduction therapy, also called alcohol septal ablation, has been used recently as a percutaneous catheter-based intervention to improve left ventricular outflow tract obstruction and thereby improve symptoms. The reported results of this procedure have shown impressive reductions in gradient and improvement in symptoms at relatively low risk. The most common complication of the procedure, development of complete heart block requiring a permanent pacemaker, has improved in recent studies with refinements of the procedural technique. Nonsurgical septal reduction therapy has been shown to improve diastolic function, decrease left ventricular hypertrophy and mass, and cause changes at the cellular and molecular level that improve myocardial function. Reported results at 1 year follow-up continue to show benefit, and long-term studies are ongoing.
