Intraoperative mapping and radiofrequency ablation of the His bundle in a patient with complex congenital heart disease and intractable atrial arrhythmias following the Fontan operation.
نویسندگان
چکیده
Intraoperative mapping and radiofrequency ablation of the His bundle (with epicardial ventricular pacing) were performed in an 18-year-old woman with complex congenital heart disease and intractable chronic atrial arrhythmias following the Fontan operation. The presence of complex intracardiac anatomy as well as the exclusion of the atrioventricular conduction tissue from the systemic venous circulation strongly influenced the technical approach.

Electrophysiological mapping and ablation of intra-atrial reentry tachycardia after Fontan surgery with the use of a noncontact mapping system.
BACKGROUND Atrial tachyarrhythmias are a complication of Fontan surgery. Conventional electrophysiological mapping and ablation techniques are limited by the complex anatomic and surgical substrate and a high arrhythmia recurrence rate. This study investigates the use of noncontact mapping to identify arrhythmia circuits and guide ablation in Fontan patients. METHODS AND RESULTS Eleven arrhyt...

متن کاملAtrial Fibrillation in Patients with Congenital Heart Disease.
Advances in surgical techniques have led to the survival of most patients with congenital heart disease (CHD) up to their adulthood. During their lifetime, many of them develop atrial tachyarrhythmias due to atrial dilatation and scarring from surgical procedures. More complex defects and palliative repairs are linked to a higher incidence and earlier occurrence of arrhythmias. Atrial fibrillat...
