Acute and follow-up results of laser angioplasty: single center experience.

Excimer laser angioplasty was used to treat total occluded coronary arteries and instent restenosis lesions with high success rate. To assess immediate and long-term results of patients treated with excimer laser, we analyzed demographic information and the immediate results of 44 patients who underwent ELCA. The patients were followed up and assessed for clinical restenosis. The initial success rate of ELCA was 86.4 per cent which is comparable to plain balloon angioplasty performed during the same period. Clinical restenosis was 29 per cent. In conclusion, ELCA for patients with coronary artery disease can be performed with initial high success rate and reasonable long-term restenosis.

Radiofrequency ablation of cardiac arrhythmia: the first fifty cases experience in Siriraj Hospital.

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.
