Intracardiac echocardiography in a case with previous failed cavotricuspid isthmus ablation.
The Eustachian ridge (ER) can present an obstacle to cavotricuspid isthmus (CTI) ablation. We describe a case, where intracardiac echocardiography revealed a prominent ER as a likely reason for a previous failed CTI ablation and guided the looping of the ablation catheter around the ER, resulting in an ultimately successful ablation.
