Aims To describe the role of left atrial (LA) epicardial conduction and targets of ablation in
biatrial tachycardias (BiATs). Methods and results Consecutive patients with BiAT diagnosed …

From anatomy and diagnostic criteria through specific mapping and ablation techniques,
Catheter Ablation of Cardiac Arrhythmias, 4th Edition, covers all you need to know in this fast …

Introduction Beyond pulmonary veins (PV) isolation, the ablation strategy for persistent atrial
fibrillation (AF) remains controversial. Substrate ablation may provide a high termination rate …

Background An optimal strategy for left atrial ablation in addition to pulmonary vein isolation
(PVI) in patients with persistent atrial fibrillation (AF) has not been determined. Methods and …

The Ligament of Marshall (LOM) is a remnant of the embryonic sinus venosus and the left
cardinal vein, containing a combination of fat, fibrous tissue, blood vessels, muscle bundles …

Background: Atrial fibrillation ablation–related atrial tachycardia (AT) is complex and may
demonstrate several forms: anatomic macroreentrant AT (AMAT), non-AMAT, and focal AT …

Aims We hypothesized that an epicardial approach using ethanol infusion in the vein of
Marshall (EIVOM) may improve the result of ablation for perimitral flutter (PMF). Methods and …

Background Mitral isthmus gaps have been ascribed to an epicardial musculature
anatomically related to the great cardiac vein (GCV) and the vein of Marshall (VOM). Their …

Objectives This study sought to describe arrhythmia characteristics using ultra-high density
(UHD) mapping of macro-re-entrant left atrial flutter (LAFL) which propagate via epicardial …

Background A novel “LUMIPOINT” software in the Rhythmia system (Boston Scientific)
displays a histogram of activated area over the entire atrial tachycardia (AT) cycle length …
