Excellent results have been described for surgical relief of left ventricular outflow tract obstruction in patients with hypertrophic obstructive cardiomyopathy. Transaortic septal myectomy is technically demanding, especially when the lesion extends deep to the midcavity of left ventricle. A loop electrosurgical electrode is used to satisfactorily circumvent this problem.
