Article Synopsis
- Treatment of recurring atrial flutter can be difficult due to anatomical challenges that hinder effective linear ablation.
- A case involving a 54-year-old patient with recurring peri-mitral flutter was successfully treated using bipolar ablation to create a complete conduction block.
- This method offers a viable alternative to traditional ablation techniques when deeper lesions are needed for effective treatment.
Mechanisms of Mitral Isthmus Reconnection After Ablation With and Without Vein of Marshall Ethanol Infusion.
JACC Clin Electrophysiol
November 2024
Division of Cardiac Electrophysiology, Houston Methodist DeBakey Heart and Vascular Center, Houston, Texas, USA. Electronic address:
Background: Reconnection of the mitral isthmus (MI) is common after radiofrequency ablation (RFA). Vein of Marshall ethanol infusion (VOMEI) expedites MI ablation, but long-term results are unclear.
Objectives: This study sought to determine anatomic substrates of failed MI ablation, with and without VOMEI.
Anatomical and Electrophysiological Characteristics of Dual-Loop Re-Entry in Atypical Atrial Flutter: Implications for Mapping and Catheter Ablation.
J Clin Med

Cardiology Division, Geneva University Hospitals, Rue Gabrielle-Perret-Gentil 4, 1205 Geneva, Switzerland.
Atypical atrial flutter (AFL) can be challenging to ablate, especially when involving dual-loop re-entry. We sought to assess the electroanatomical characteristics of single- and dual-loop AFLs in patients undergoing catheter ablation. We analyzed 25 non-cavotricuspid isthmus-dependent macro-re-entrant AFL in 19 consecutive patients.

Electronic address:
Background: Linear and complex electrogram ablation (LCEA) beyond pulmonary vein isolation (PVI) is associated with an increase in left atrial macro-re-entrant tachycardias (LAMTs). Posterior wall isolation (PWI) is increasingly performed to improve AF ablation outcomes. However, the impact of PWI on the incidence of LAMT is unknown.
