Abstract | BACKGROUND: METHODS AND RESULTS: To determine the early incidence of sinus node dysfunction, hospital records and perioperative ECGs were reviewed in all 287 patients having had a staged Fontan operation between January 1990 and December 1995. A cross-sectional analysis was performed on 220 of 239 surviving patients (92%) to determine the late incidence of sinus node dysfunction. Sinus node dysfunction was present in 7% of the patients before and in 15% after the hemi-Fontan. Although most patients (81%) regained normal sinus node function between the 2 stages, 23% had sinus node dysfunction in the early postoperative period after the Fontan. Of the 95 patients followed for > 4 years after the Fontan operation, 44% had sinus node dysfunction. However, at a mean follow-up of 3.5 +/- 1.7 years, only 16 patients (6.7%) had received a pacemaker and only 10 (4.1%) had documented atrial flutter. CONCLUSIONS:
