Abstract

Introduction: Atrial fibrillation (AF) is common among adult patients with atrial septal defect (ASD). However, the fate of preoperative AF is not well known. This study examined the course of preoperative AF after ASD correction. Methods: Between January 2001 and May 2010, a total of 471 adult patients (131 men, 42 ± 14 years) underwent transcatheter closure (n=237, 50%) or surgical repair (n=234, 50%) of ASD. Preoperative and postoperative AF was confirmed by ECG or Holter monitoring taken every 3 and 12 months, respectively. Results: Forty patients had AF before transCatheter closure (n = 10) or surgical repair (n=30) of ASD. Compared with patients without AF, patients with AF were older, more likely to be male and had larger left atrial size. During the follow-up period of 44 ± 28 months, excluding 15 patients who had undergone surgical ASD repair and the Maze operation, sinus rhythm was maintained in 7 (87.5%) out of 8 patients with paroxysmal AF. However, only 3 (17.6%) out of 17 patients with persistent AF maintained sinus rhythm. In 15 patients treated with concurrent Maze operation, 12 (80.0%) patients maintained sinus rhythm. Conclusions: Hemodynamic correction of ASD was effective in converting preoperative AF to sinus rhythm in most patients with paroxysmal AF. Therefore, concurrent Maze operation or Catheter ablation before ASD repair should be considered only in patients with persistent AF.
