ARRHYTHMIA RECURRENCE IN ADULT PATIENTS WITH SINGLE VENTRICLE PHYSIOLOGY FOLLOWING SURGICAL FONTAN CONVERSION

To evaluate the incidence of atrial tachy-arrhythmia (AT) recurrence following conversion from right atrial-pulmonary artery (RA-PA) Fontan to total cavopulmonary connection (TCPC) in adults.AT is a recognized sequel of Fontan palliation, especially in RA-PA Fontans, and is associated with significant morbidity. While catheter ablation achieves fairly reliable short-term success with low morbidity, conversion to TCPC with arrhythmia surgery is a...
