Atrial tachycardias (ATs) may be classified into three broad categories: focal ATs,
macroreentry and localised reentry–also known as 'microreentry'. Features that distinguish …

Background: Achieving bidirectional mitral isthmus (MI) block using radiofrequency catheter
ablation (RFCA) alone is challenging, and MI reconnection is common. Adjunctive vein of …

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 …

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 …

Importance Success rates of pulmonary vein isolation (PVI) are modest for persistent atrial
fibrillation (AF). Additional linear ablation beyond PVI has not been proved superior to PVI …

Left atrial tachycardias (ATs) most commonly occur after catheter or surgical ablation of atrial
fibrillation and in patients with atrial myopathies. Pre‐existing scar in the left atrium (LA) can …

Objectives This study sought to systematically evaluate the ability of a high-resolution
mapping system (Rhythmia, Boston Scientific, Marlborough, Massachusetts) to rapidly and …

Background Reconnection of the mitral isthmus (MI) is common after radiofrequency
ablation (RFA). Vein of Marshall ethanol infusion (VOMEI) expedites MI ablation, but long …

Background The vein of Marshall (VOM), which is surrounded by the Marshall bundle (MB),
behaves as an epicardial connection bypassing the mitral isthmus. The influence of …
