Transcoronary chemical ablation of ventricular tachycardia was performed in 2 patients with refractory ventricular tachycardia in Fu Wai Hospital. The procedures were successful. 1.5 ml sterilized ethanol (95%) was given to 1 patient and 0.8 ml to the other. The 2 patients were cured and no arrhythmia was found during 32-months and 4-months follow-up period respectively. One patient developed a limited inferior wall myocardial infarction after 1.5 ml ethanol. No other complications were observed. We found that after careful transcoronary mapping with saline and antiarrhythmic drugs, chemical ablation could prevent further episodes of the arrhythmia in selected high risk patients.
