Prostaglandin E-mediated Vascular Remodeling of the Ductus Arteriosus and Ductus-Dependent Congenital Heart Diseases
Prostaglandin E2 (PGE2) is known to be a potent endogenous vasodilator of the ductus arteriosus (DA) [1], which is an essential bypass artery between the aorta and the main pulmonary artery. In some types of congenital heart diseases (CHDs) such as hypoplastic left heart syndrome or pulmonary atresia, blood flow through the DA is required for systemic or pulmonary circulation. Life-threatening ...
متن کاملHistopathology of the ductus arteriosus after prostaglandin E1 administration in ductus dependent cardiac anomalies.
The histology of the ductus arteriosus was studied after prostaglandin E1 (PGE1) administration in 4 infants with ductus dependent cardiac malformations. Pronounced pathological changes were found in each instance. The changes consisted of oedema of the media with separation of medial components by clear spaces, pathological interruptions of the internal elastic lamina, and intimal lacerations,...
متن کاملFormalin infiltration of ductus arteriosus in cyanotic congenital heart disease.
Formalin infiltration of the ductus arteriosus was performed in 13 neonates with pulmonary atresia (three with ventricular septal defect, two with tricuspid atresia, and eight with intact ventricular septum, one of whom had Ebstein's anomaly) in an attempt to maintain duct patency. Nine patients had an additional retrograde pulmonary valvotomy and one a Blalock-Taussig shunt. The mean preoperat...
متن کاملEDITORIAL COMMENT Congenital Ductus Arteriosus Aneurysm*
Congenital ductus arteriosus aneurysm (DAA) is a saccular or fusiform dilation and elongation of the ductus arteriosus. By chest X-ray, it is recognized as a ductal bump (1). More recently, echocardiography has been the primary modality used to demonstrate the pathology (2,3). Although most commonly diagnosed within the first two months after birth (2), the pathology may also be diagnosed prena...
متن کاملductus arteriosus
We have modified and applied to selected outpatients the transvenous approach to correction of patent ductus arteriosus (PDA) with the Rashkind PDA Occluder. Modifications included establishing the diagnosis and PDA anatomy before catheterization with echocardiography. The sedation/anesthetic regimen was altered to meet the needs with respect to transcatheter PDA closure rather than diagnostic ...
