Catheter Ablation of Incisional Atrial Tachycardia.
Tachycardias after atrial incisions represent frequent and serious problem. The majority of them are based on a re-entry electrical activation around a combination of anatomic and surgically created obstacles. Considering significant progress of cardiovascular surgery during the last decade along with potential large amount of open-heart procedures in the near future the number of incisional ta...
متن کاملCatheter ablation of Atrial Incisional Tachycardia mistaken for Atrial flutter
Incisional sustained tachycardias are frequent in patients who have undergone a surgical repair of interatrial defect. A 43-year-old woman with drug refractory, highly symptomatic, persistent atrial tachycardia in the last year, was referred to our unit for catheter ablation. The patient had undergone a cardiac operation for repairing interatrial secundum ostium type defect with a patch five ye...
متن کاملFocal atrial tachycardia: new insight from noncontact mapping and catheter ablation.
BACKGROUND This study investigated the electrophysiologic characteristics, atrial activation pattern, and effects of radiofrequency (RF) catheter ablation guided by noncontact mapping system in patients with focal atrial tachycardia (AT). METHODS AND RESULTS In 13 patients with 14 focal ATs, noncontact mapping system was used to map and guide ablation of AT. AT origins were in the crista term...
متن کاملFocal atrial tachycardia surrounding the anterior septum: strategy for mapping and catheter ablation.
BACKGROUND Focal atrial tachycardias (ATs) surrounding the anterior atrial septum (AAS) have been successfully ablated from the right atrial septum (RAS), the aortic cusps, and the aortic mitral junction. However, the strategy for mapping and ablation of AAS-ATs has not been well defined. METHODS AND RESULTS Of 227 consecutive patients with AT, 47 (20.7%; mean age, 56.3±11.6 years) with AAS-A...
متن کاملWhich patients recur as atrial tachycardia rather than atrial fibrillation after catheter ablation of atrial fibrillation?
INTRODUCTION The ablation gaps have been known as the main mechanism of recurrence as atrial tachycardia (AT) rather than atrial fibrillation (AF) after AF catheter ablation. However, AF organization due to reduction of critical mass or focal trigger may also be the mechanism of AT recurrence. We sought to find out the main clinical factors of recurrence as AT rather than AF after AF ablation i...
