Prospective study of the incidence and determinants of arrhythmia after total cavopulmonary connection.

Atrial distension after Fontan operation may predispose to arrhythmia. Modifications aimed at decreasing the extent of right atrial distension (total cavopulmonary connection, TCPC) have been associated with a lower incidence of early arrhythmia, but serial evaluation has not been performed.All 119 patients undergoing TCPC between March 1987 and December 1993 were enrolled in a prospective study to evaluate the incidence and determinants of...
