Abstract
Pulmonary atresia (PA) is a form of congenital pulmonary dysplasia in which the PV does not form properly; the duct of the RV and the pulmonary artery have an interruption in which there may be a residual ligament, or the artery may be totally separated. The range of pulmonary atresia may be limited or diffuse, and the portion of the atresia may be single or multiple. Generally, PA is classified according to two types: 1) PA with intact ventricular septum (PA-IVS) and 2) PA with VSD (PA-VSD) (Fig. 27.1c). The IVS type involves the arterial duct, accompanied by hypoplasia of the RV and the TV and may even include deformity of the coronary artery. The VSD type is characterized by underdevelopment of the RVOT accompanied by a large VSD and overriding of the aorta.
