Radiofrequency catheter ablation of accessory pathways associated with a coronary sinus diverticulum.
In two patients with a symptomatic posteroseptally localized accessory atrioventricular pathway, but with distinct electrocardiographic patterns, a coronary sinus diverticulum appeared to be the site of this connection. Radiofrequency catheter ablation in the diverticulum was implemented to interrupt the pathway in both cases. This study demonstrates the necessity to perform coronary sinus angiography when ablation attempts in the posteroseptal region are not immediately successful, or optimal signals are not detected.
