Understanding Functional Substrate Mapping Techniques In VT Ablation To Improve Outcomes

Mapping and ablation of post-infarct related ventricular tachycardia (VT) remains a challenge. Conventional activation and entrainment methods are limited by poorly tolerated VT’s, multiple VT’s, complex circuits and the deleterious effects of mapping in VT on cardiac, renal and cerebral function. The resultant effect is poor long term outcomes.

Classical substrate mapping techniques predominantly involve mapping ventricular scar substrate in intrinsic rhythm, however, VT circuits may be dynamic, and substrate characteristics may not be static or prevalent in intrinsic rhythm. Emerging functional substrate assessment methods of VT ablation may improve outcomes from VT ablation and may be safer by reducing the need for the patient to be in VT for prolonged periods of time.

This webinar discusses presently available techniques.
