May inform ablation strategies for recurrent VA; leaves open need for randomized confirmation of innovations.
Catheter ablation for the management of recurrent ventricular arrhythmias (VAs) is an emerging technology, with good efficacy in selected patients. It is an effective treatment for recurrent VA and can terminate VA during electrical storm. Recent innovations enhance the accuracy of ventricular mapping, allowing for substrate modification while the patient remains in sinus rhythm, thus facilitating the treatment of different types of VA. Epicardial ablation is now a feasible option for treating VA and increases the likelihood of success in certain types of VA. Percutaneous hemodynamic support facilitates successful ablation during poorly tolerated VA. This article reviews recent advances in catheter ablation techniques for VA and approaches to the management of specific types of VA, with a view toward future developments.
