Summary:Non-surgical transpericardial approach for catheter-based epicardial radiofrequency ablation of post-infarction left ventricular tachycardia has been described as an alternative and additive procedure to standard endocardial technique for delivery of radiofrequency energy in difficult situations. We report our initial experience with this approach in three patients of post-infarction recurrent ventricular tachycardia, refactory to multiple antiarrhythmic drugs. Ablation was successful in terminating the tachycardia in two and in modifying the circuit to be amenable for control with single antiarrhythmic drug in one patient. There were no serious acute or long-term complications related to the procedure. Epicardial approach is an effective and safe adjunct to standard endocardial ablative technique for patients of post-infarction ventricular tachycardia.
