Catheter ablation%Ventricular tachycardias
Catheter ablation is now an important option to control drug-refractory ventricular arrhythmias.Ablation is highly effective for ventriculal arrhythmia originating from outflow tract and idiopathic left ventricular tachycardias(VT).Catheter ablation of hemodynamically unstable scar-related VT,which frequently occurs in patients with remote myocardial infarction,dilated/hypertrophic cardiomyopahties and after surgical correction of congenital heart disease,is still a challenge for electrophysiologists.In the last decade,catheter ablation in this field has rapidly evolved and has made a big progression with a introduction of 3-D mapping system and new ablation catheter.However,it requires further investigation to identify the high-risk patients and to understand the arrhythmia substrate and improve lesion formation in the ventricle.
