ABSTRACT
Successful transcatheter coil embolizations of the left lower lobe pulmonary arteriovenous fistulas, the first case in Thailand, in a 6-year-old boy presenting with increased cyanosis was reported. Transcatheter management of unusual sites of right-to-left intrapulmonary shunting can provide gratifying clinical improvement in some children.

In conclusion, elective stent placement, compared to angioplasty, has a higher clinical success rate. However, in our early experience major complications did occur.

Attempted angioplasty of totally occluded vessels may be done. However, a lower success rate is expected compared to those with subtotal occlusion. The complication rate is comparable to that of partial occlusion in experienced hands.

In our series of 50 consecutive patients with a wide variety of cardiac arrhythmia, a combined approach to electrophysiological diagnosis and definitive treatment with catheter ablation was associated with a high degree of efficacy, low procedural complication and low rate of arrhythmia recurrence. The radiofrequency catheter ablation should be considered as the acceptable or preferable first line treatment in patients with supraventricular tachycardia and idiopathic ventricular tachycardia.

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.
