A review of cavotricuspid isthmus ablation for atrial flutter highlights regional anatomic challenges that complicate achieving bidirectional block and presents approaches to troubleshooting.
This review discusses anatomic challenges and troubleshooting approaches for achieving bidirectional block during cavotricuspid isthmus ablation for atrial flutter.
In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure. However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve.1 Using a case example, we review common challenges with CTI ablation, discuss the important anatomic considerations that are relevant to procedural difficulty, and present approaches to troubleshooting.
Christopoulos et al. (Sun,) conducted a review in Cavotricuspid isthmus (CTI)-dependent atrial flutter. Cavotricuspid isthmus (CTI) ablation was evaluated.
