[Ablation of idiopathic ventricular tachycardia with left bundle-branch block morphology located in the pulmonary trunk].
We report the case of a 26-year-old female patient with palpitations and presyncopes due to nonsustained ventricular tachycardia, who had no structural heart disease. The patient underwent electrophysiological study in an attempt to ablate the arrhythmogenic focus, whose location was determined by using mapping criteria. Because mapping of the right ventricular outflow tract was not successful, the catheter was placed inside the pulmonary artery with satisfactory mapping of the arrhythmogenic focus, and tachycardia was eliminated as soon as radiofrequency was initiated. The patient has remained asymptomatic for 14 months, with no treatment with antiarrhythmic drugs, and no arrhythmias on serial 24-hour Holter.
