Does radiofrequency ablation terminate incessant left ventricular tachycardia?
Does radiofrequency ablation terminate incessant left ventricular tachycardia?
Radiofrequency catheter ablation can successfully terminate incessant left ventricular tachycardia and should be considered as first-line therapy in experienced centers.
Supports radiofrequency ablation terminating incessant LV tachycardia in select cases; leaves open first-line role pending prospective data.
INTRODUCTION: Incessant ventricular tachycardia is a rare arrhythmia which can be life threatening. Treatment with anti-arrhythmic agents may occasionally fail. CLINICAL PICTURE: We report 2 cases of incessant ventricular tachycardia. The first case was a young man with idiopathic left ventricular tachycardia who was in incessant ventricular tachycardia despite treatment with multiple anti-arrhythmic drugs and developed dilated cardiomyopathy. The second case was an asymptomatic girl with the incidental finding of an incessant ventricular tachycardia which originated from the left ventricular outflow tract. TREATMENT AND OUTCOME: Both patients underwent electrophysiologic study and radiofrequency ablation with complete termination of the tachycardia. CONCLUSION: Radiofrequency catheter ablation in experienced centres should be the first-line therapy for incessant ventricular tachycardia.
