Background:
Although total cavopulmonary connection without use of prosthetic material appeared to be a promising surgical procedure that would retain potential growth of the intraatrial tunnel, midterm incidence of arrhythmia remains unknown.
Methods:
Twelve patients underwent modified total cavopulmonary connection. A prosthetic material was not used in 5 patients (group F) and was used in 7 patients (group P). A retrospective review of the perioperative electrocardiogram and ambulatory monitoring were performed.
Results:
All patients revealed regular sinus rhythm before the operation. In the early postoperative period, the incidence of sinus node dysfunction was higher in group F than in group P (80% versus 28.6%). This difference no longer existed by hospital discharge (group F, 20%; group P, 14.3%). In the midterm follow-up period, sinus node dysfunction was detected in 4 patients of group F (80%) and 1 patient of group P (14.3%). Transient tachyarrhythmia was detected in 1 patient of group F and 3 patients of group P.
Conclusions:
Modified total cavopulmonary connection without use of prosthetic material affected unfavorably the sinus node in the early and midterm postoperative period.
