| Popis: | Implantable cardioverter defibrillator shocks are common with catheter ablation procedures being increasingly used to minimize recurrent ventricular tachycardia (VT). The purpose of the review is to provide an update on approaches to identify critical portions of VT circuits. VT ablation has evolved from a surgical approach to a percutaneous minimally invasive approach. Pre-procedural planning including the use of cardiac MRI can provide valuable information about the underlying substrate. Mapping of the VT circuit with multipolar catheters and improved detection of slow conduction zones in sinus rhythm have reduced procedural time, decreased the need to map in VT, and facilitated improved procedural success. In this review, we revisit the four principle techniques for mapping ventricular tachycardia: activation mapping, entrainment mapping, pace mapping, and substrate mapping. We highlight recent enhancements in these techniques. |
