Hypertrophic obstructive cardiomyopathy. The use of a diathermy loop for septal resection

Abstract

The report describes the use of diathermy loop to resect the left ventricular component of the hypertrophied septum in hypertrophic obstructive cardiomyopathy (HOCM). The technique is simple to perform and is able to reduce significantly the systolic pressure gradient across the left ventricular outflow tract.
