We studied the morphology of the ductus arteriosus in 14 infants, ages 2--90 days. Eight (group 1) had pulmonary atresia (structural and functional) with an intact interventricular septum; six (group 2) had pulmonary atresia with a ventricular septal defect. The inferior angle of the ductus arteriosus at the aortic junction was measured in each patient. In group 1, this angle was obtuse in all ...

Over the past 2 decades several investigators (1-4) have attempted to demonstrate with a variety of methodologies that the morphologically right ventricle in p miens with either pulmonary atresia or critical pulmonary stenosis can grow after surgical intervention . That growth should occur in a morphologically right ventricle whose dimensions are nearly normal or in an occasional patient with a...

An indexed offset distance of the tricuspid septal leaflet ⩾8 mm/m2 is a quantitative criterion for the diagnosis of Ebstein's anomaly. The purpose of this study was to investigate the validity of this criterion for the discrimination of Ebstein's anomaly from pulmonary atresia with intact ventricular septum in neonatal patients. A total of 122 neonatal patients, 56 with Ebstein's anomaly and 6...

Pulmonary artery coarctation often happens in patients with pulmonary atresia. The correction has been usually performed using cardiopulmonary bypass and during the neonatal period, influencing pulmonary artery development and prognosis. Three patients with pulmonary atresia with PDA underwent correction using median sternotomy without cardiopulmonary bypass. The PDA maintained the arterial sat...

UNLABELLED An infant, showing peripheral cyanosis, was born after lower abdominal peripheral caesarian section of the pregnant women having TORCH positive test with the infection of Toxoplasma gondiiand Cytomegalovirus. She had three abortions prior to this pregnancy. Doppler echocardiography of the baby showed profound intracardiac defects. After birth, echocardiography was carried out for dia...

The records of 15 infants with pulmonary atresia and 19 infants with critical pulmonic stenosis and intact ventricular septum, all under 1 year of age, have been reviewed. Symptoms started earlier and were more severe in the group with pulmonary atresia. All patients showed arterial unsaturation, and many had congestive heart failure. The electrocardiogram was the most helpful tool in different...

Five neonates with congenital tricuspid incompetence due to severe tethering of the tricuspid valve to the right ventricle by abnormal chordal and papillary muscle attachments are described. The abnormality was called tricuspid valvular dysplasia (TVD) if the basal insertion of the valve was normal and the Ebstein malformation if it was displaced into the sinus portion of the ventricle. In the ...

Doppler echocardiography was used to evaluate blood flow in the pulmonary artery in 14 patients 2 to 42 months (mean (SD) 17 (12) months) after a modified Fontan operation incorporating a direct atriopulmonary anastomosis. Preoperatively six patients had tricuspid atresia, six had a double inlet left ventricle, and two had pulmonary atresia with an intact ventricular septum. The postoperative r...
