A single delivery of low-energy (11 W) radiofrequency ablation successfully eliminated incessant, monomorphic ventricular tachycardia originating from the left coronary cusp in a 22-year-old man.
Case Report (n=1)
No
Repetitive monomorphic ventricular tachycardia with a morphology of inferior axis and left bundle branch block pattern in patients without structural heart disease commonly originates from the right ventricular outflow tract. We report the case of a 22-year-old man with an incessant, monomorphic ventricular tachycardia with a similar morphology originating from the left coronary cusp, which was confirmed by perfect pace mapping, local ventricular activation preceding the onset of QRS by 25 mse, and eliminated by a single delivery of low-energy (11 W) radiofrequency currents.
Sadanaga et al. (Fri,) conducted a case report in Repetitive monomorphic ventricular tachycardia (n=1). Radiofrequency ablation was evaluated on Elimination of ventricular tachycardia. A single delivery of low-energy (11 W) radiofrequency ablation successfully eliminated incessant, monomorphic ventricular tachycardia originating from the left coronary cusp in a 22-year-old man.
