[Septal ablation in the treatment of hypertrophic myocardiopathy].
Hypertrophic cardiomyopathy is a relative frequent disease and probably the most common genetic transmitted cardiovascular disease. Fortunately, the more aggressive varieties of the disease represent the less common manifestation of it. Outflow left ventricular obstruction is present in about 25 to 30% of the cases. Recently, septal ablation by means of the selective alcohol injection in left anterior descendent septal branches was introduced as a therapeutic alternative in cases associated with left ventricular outflow obstruction. Results with this technique have been encouraging with a success rate over 90%, and a low rate incidence of complications and mortality. These results are similar to those of surgical myectomy. We review indications, technique, and results obtained with this procedure.
