ABSTRACT
Twenty patients with symptomatic monomorphic ventricular tachycardia (VT) underwent radiofrequency (RF) energy catheter ablation. Four patients (20%) had underlying heart disease (1 prolapse mitral valve, 1 dilated cardiomyopathy and 2 myocarditis). Five patients (25%) had left sided VT and right sided VT in the remainder (75%). Radiofrequency catheter ablation was initially successful in all patients without major complication. Recurrence occurred in three patients (15%). In conclusion, RF ablation is an effective treatment for symptomatic monomorphic right and left sided VT especially in patients who do not want long term antiarrhythmic agents.

Successful percutaneous coil embolization of aortopulmonary collaterals and balloon-expandable stent implantation of left pulmonary artery stenosis in a child with hypoplastic right heart syndrome were reported, Presently, interventional cardiac catheterization is a very useful treatment strategy in congenital heart diseases unamenable to or inaccessible for surgery.

In conclusion, we reported two cases of idiopathic right and left VT who presented with syncope and palpitation. The surface QRS during VT and electrophysiologic studies showed the site of origin at RVOT in the first case and inferoapical area of left ventricle in the other. RF ablation was an effective treatment in both patients without any serious complication. Both of them are free of symptoms without any medication.

We reported the first high pressure stent assisted balloon angioplasty successfully implanted in this country. The use of intracoronary stent and its future direction were also reviewed. Regimen for post stent can be adjusted for each individual patient.
