Successful management of recurrent ventricular tachycardia by electrical isolation of anterolateral papillary muscle

Abstract

a w a p F ( i b ntroduction adiofrequency ablation is increasingly used as adjuncive therapy for the management of ventricular arrhythias. Ablation is performed to decrease painful imlantable cardioverter-defibrillator (ICD) shocks and to mprove quality of life. The propensity for difficulty with blation as a result of epicardial and deep midmyocardial ubstrate is well recognized. Although endocavitary tructures, such as false tendons, have been suggested to e arrhythmogenic, the role, if any, of the papillary uscles as the origin of ventricular tachycardia has not een described.
