title: [Echocardiographic and Doppler study of pulmonary atresia with an intact interventricular septum].
abstract: Pulmonary atresia with intact ventricular septum represents a congenital cardiac lesion for which the prognosis depends on the patency of the ductus arteriosus. Nine children with pulmonary atresia and intact ventricular septum underwent echocardiographic studies before cardiac catheterization trying to visualize the anatomy of the outflow tract of the right ventricle, the dimension of the ventricular cavity, the characteristics of the tricuspid valve and finally the size and integrity of the interventricular septum. Using Doppler ultrasound it was possible to evaluate the function of the tricuspid valve and the patency of the ductus arteriosus. The results obtained were correlated with the angiographic and anatomic studies. We concluded that noninvasive assessment of this malformation permits an excellent correlation with the angiographic and anatomic studies.
