Patients who suffer from ventricular tachycardia following myocardial infarction are at a high risk of sudden death. \u00a0This risk can be reduced by implantable cardioverter defibrillator (ICD) insertion, however patients with an ICD who receive ICD shocks have a decreased quality of life and increased mortality compared with patients who do not receive shocks, even if the shocks are inappropriate.<\/div>\n
The Ventricular Tachcardia Ablation in Coronary Heart Disease (VTACH) study was a prospective, randomised controlled trial designed to investigate whether catheter ablation of ventricular tachycardia prior to ICD insertion could be beneficial. \u00a0110 patients with stable ventricular tachycardia, prior myocardial infarction, and a left ventricular ejection fraction of less than 50% were randomised to either catheter ablation and an ICD (n=54) or an ICD alone (n=56). \u00a0Patients were followed up for at least one year; the primary endpoint was the time to first recurrence of either ventricular tachycardia or ventricular fibrillation.<\/div>\n

<\/p>\n

The mean follow-up period was 22.5 months, and time to recurrence of arrhythmia was longer in the ablation group (median 18.6 months) than in the control group (5.9 months). \u00a0At 2 years, 47% of patients who had received ablation were alive and had not suffered a recurrent ventricular arrhythmia, compared to only 29% in the control group (p=0.045). \u00a0Nine patients died during the study; five in the ablation group and four in the control group.<\/div>\n
Conclusions:<\/div>\n
Prophylactic ablation of a ventricular arrhythmia prior to ICD implantation prolonged the time recurrence of ventricular tachycardia in patients with stable VT, previous infarction, and a low ejection fraction. \u00a0Although larger numbers and longer follow-up are needed to prove a definite clinical benefit, this technique should be considered before implantation of an ICD in such patients.<\/div>\n
