A 48-year-old woman was referred to catheter ablation for symptomatic premature ventricular contraction (PVC). Left ventricular endocardial mapping was performed via a retrograde aortic approach using a 3-dimensional electroanatomic mapping system (Carto3; Biosense Webster, Diamond Bar, CA). PVCs were only present during exertion. No PVC was present at baseline. Isoproterenol infusion was started and initiated PVCs when heart rate was ≈100 beats per minute. PVC origin was identified at the inferoseptal region mainly based on pacemapping. Radiofrequency ablation was performed using a 3.5-mm open-irrigation catheter that enables contact force monitoring (Smartouch; Biosense Webster). On a midventricular site (site 1), radiofrequency was delivered for 2 minutes (35 W; contact force, 20 g ) resulting in successful termination of the ectopic. Unfortunately, isoproterenol infusion unmasked a second morphology close to the previous one, possibly because of a change of exit site. After a combination of pacemapping and activation mapping, …

Although catheter ablation has been successful in reducing the recurrence of ventricular tachycardia in patients with ischemic disease, outcomes in patients with nonischemic cardiomyopathy (NICM) have not met with the same results. Success is predicated on a methodical approach to diagnosis of disease type and identification of critical substrate, and the ablation strategies used. Cardiac MRI with delayed enhancement is able to identify areas of substrate involvement, particularly in situations when conventional catheter mapping is not able to do so. Radiofrequency needle, irrigated bipolar radiofrequency, and transcoronary alcohol ablation are effective and alternative techniques to endocardial and epicardial ablation.

With the widespread use of implantable cardioverter-defibrillators, an increasing number of patients present with ventricular tachycardia (VT). Large multicentre studies have shown that ablation of VT successfully reduces recurrent VT and this procedure is being performed by an increasing number of centres. However, for a number of reasons, many patients experience VT recurrence after ablation. One important reason for VT recurrence is the presence of an epicardial substrate involved in the VT circuit which is not affected by endocardial ablation. Epicardial access and ablation is now frequently performed either after failed endocardial VT ablation or as first-line treatment in selected patients. This review will focus on the available evidence for identifying VT of epicardial origin, and discuss in which patients an epicardial approach would be benefitial.
