A patent ductus arteriosus, very common in the preterm infant (incidence up to 70% in infants less than 28 weeks gestational age), causes a left-to-right shunt leading to overload of the pulmonary circulation and low systemic blood flow. These hemodynamic anomalies are associated with a higher incidence of respiratory, neurological, and digestive complications of prematurity, as well as a highe...

BACKGROUND Congenital pulmonary valve stenosis and patent ductus arteriosus are common congenital heart defects in dogs. However, concurrence of atypical pulmonary valve stenosis and patent ductus arteriosus is uncommon. This report describes the anatomic, histopathologic, and echocardiographic features in a dog with concomitant pulmonary valve stenosis and patent ductus arteriosus with atypica...

The diagnosis of patent ductus arteriosus is difficult when the classic continuous murmur is not present. In infancy, in the presence of cardiac decompensation and when the ductus approximates the aorta in size, the continuous murmur is frequently absent. A correct diagnosis may be important, however, for a large patent ductus arteriosus can cause serious difficulty. Early surgical treatment ma...

Introduction Ibuprofen is used widely to close patent ductus arteriosus in preterm infants. The anti-inflammatory activity of ibuprofen may also be partly due to its ability to scavenge reactive oxygen species and reactive nitrogen species. We evaluated the interaction between oxidative status and the medical treatment of patent ductus arteriosus with two forms of ibuprofen. Materials and metho...

The classic findings of a patent ductus arteriosus in a young individual are familiar to most physicians. However, it has been appreciated that several factors, principally pulmonary hypertension or pulmonary artery dilatation in the absence of appreciable hypertension, may significantly alter the classic image and lead to the erroneous diagnosis of ventricular septal defect. In 10 surgically p...

We reported a 21-year-old patient with strict descending aorta coarctation and small post-ductal patent ductus arteriosus, complicated with abortion and hypertension. The patient was successfully treated by endovascular stent-graft with a single cardiac catheterization. Endovascular stent-graft is an easy, safe, and reliable intervention for the treatment of strict descending aorta coarctation ...

The effects of patent ductus arteriosus upon the circulation were studied by Eppinger, Burwell, and Gross (1). Later, Dexter, Haynes, Burwell, Eppinger, Sosman, and Evans (2) described preoperative and postoperative hemodynamic studies obtained by cardiac catheterization in a patient with patent ductus arteriosus. Since the presence of a patent ductus arteriosus can. be detected by physical exa...
