Atrial Arrhythmia after Surgical Closure of Atrial Septal Defects in Adults

Abstract

The risk of atrial flutter or atrial fibrillation in adults with atrial septal defects is related to the age at the time of surgical repair and the pulmonary arterial pressure. To reduce the morbidity associated with atrial flutter and fibrillation, the timely closure of atrial septal defects is warranted.

Improvement after Surgical Closure of Secundum Atrial Septal Defects in Adults

“…When the ASD is closed before the age of 18 years, the majority of these changes normalize [12,27]. This coincides with our results that encourage surgery without delay.…”

The effects of surgical repair on P-wave dispersion in children with secundum atrial septal defect

“…11 Changes in atrial myocardium may become more overt with age due to the continual pressure and potential volume overload. 3,15,17 Therefore, the prolonged Pmax values, in contrast to the study by Ho et al, may be attributed to the older age of ASD patients in our study (7.0±3.0 vs 2.9±4.1 years).…”

Maximizing the Effectiveness of Ablation for Arrhythmias in the Congenital Heart Patients

“…Up to 30 % of CHD patients with successful intraatrial reentrant tachycardia (IART) ablation eventually present with atrial fibrillation (AF). In atrial septal defect (ASD) patients, AF is rarely seen before the age of 40 [13], but in unrepaired patients beyond 60 years of age the incidence can approach 50 % [14]. This contrasts with a 9 % incidence of AF in patients above 80 years of age without an ASD [15].…”
