The left ventricular summit (LVS) is a common site of origin of ventricular arrhythmias (VAs) and undoubtedly represents one of the most challenging areas to map and effectively ablate VAs. Over the last several years, tremendous advancements have been made in the understanding of the anatomic relationships between the LVS and other adjacent vantage points within the right and left ventricular outflow tracts; this has facilitated a more streamlined mapping approach and more effective ablation strategies.
This issue of the Cardiac Electrophysiology Clinics is entirely focused on the LVS as a source of VAs. The anatomy of the region, the relationships with adjacent structures, and the different approaches for mapping and ablation are reviewed by international leaders in the field. We are pleased to present this work to the readers and wish to thank all the authors for their outstanding contributions.
