Safety, Efficacy, and 2-Year Outcomes of Cardiovascular Magnetic Resonance-Guided Ablation of Isthmus-Dependent Atrial Flutter.

ABSTRACT:

Background

Ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter with interventional cardiovascular magnetic resonance (CMR) has demonstrated its efficacy and safety in the initial phase for achieving bidirectional block. However, limited long-term follow-up data exist for these patients.

Case summary

Thirteen consecutive patients were included between 2021 and 2022. CMR-guided catheter ablation of CTI-dependent atrial flutter was completed successfully in 11 patients (85%). CTI ablation had to be completed in a conventional electrophysiology laboratory for 2 patients: one patient required general anesthesia due to pain during CTI ablation, and the other deteriorated into atrial fibrillation during ablation shots. Among 11 patients with procedural success, 2 (18%)
