[Reconstruction of the pulmonary outflow tract with a valved conduit (author's transl)].
La ricostruzione della via d'efflusso polmonare mediante tubo protesico valvolato
The authors describe 25 patients who underwent open heart surgery for reconstruction of the pulmonary outflow tract with a valved conduit. The following anomalies were observed: six cases of great vessels transposition, five cases of pulmonary artery atresia, five cases of truncus, three cases of tetralogy of Fallot and six cases of single ventricle. Two cases of single ventricle were treated in order to be transformed into a systemic ventricle. The pulmonary outflow was reconstructed with a valved conduit anastomosed between right atrium and pulmonary artery. This study includes pre- and postoperative hemodynamic values, surgical evaluation and a 5-months to 3-years follow-up. The authors emphasize that it is important that the surgical indications are closely related to the morphology and hemodynamics of pulmonary circulation for a better result.
