High-density automated mapping and cardiac imaging tools provide new insights into the identification and visualization of reentrant ventricular tachycardia mechanisms.
This review highlights the evolution of ventricular tachycardia ablation technologies, emphasizing the shift towards high-density automated mapping and advanced cardiac image integration to better identify and visualize reentrant circuits.
Successful mapping and ablation of ventricular tachycardias remains a challenging clinical task. Whereas conventional entrainment and activation mapping was for many years the gold standard to identify reentrant circuits in ischaemic ventricular tachycardia ablation procedures, substrate mapping has become the cornerstone of ventricular tachycardia ablation. In the last decade, technology has dramatically improved. In parallel to high-density automated mapping, cardiac imaging and image integration tools are increasingly used to assess the structural ventricular tachycardia substrate. The aim of this review is to describe the technologies underlying these new mapping systems and to discuss their possible role in providing new insights into identification and visualization of reentrant tachycardia mechanisms.
