[Risk factors in Fontan's operation]
Abstract:
The results of Fontan's procedure performed in 51 patients with various congenital heart defects were analysed. The procedure was found to have the following risk factors: the total lung resistance is above 4 mu/m2, the ejection fraction of the arterial ventricle, under 55%, serious concomitant heart defects, and additional surgical procedures that increase the scope of surgical interventions. The best results were obtained after creating a valveless atriopulmonary anastomosis; the poorest results were associated with a right atrium-pulmonary trunk anastomosis possessing its own valve.
