Repair of type I truncus arteriosus with pulmonary artery branch preservation and use of a valved PTFE conduit
Alcántara-Noguez, Carlos
ABSTRACT
Truncus arteriosus type I is a rare and complex congenital heart defect, the surgical management of which is fraught with the risk of pulmonary branch obstruction. We describe a corrective approach utilizing the Alfieri technique, with a focus on preserving the native pulmonary branch architecture, complemented by the use of a handcrafted PTFE valved conduit for right ventricular outflow tract reconstruction. This strategy mitigates anastomotic tension, thereby reducing the risk of obstruction and endocarditis, and consequently, the need for early reintervention.
