THE PRESENCE of an isolated patent ductus arteriosus can generally be determined by clinical examination. However, the differentiation of patent ductus arteriosus from the more unusual left-to-right shunts originating from the aorta is notoriously difficult, and in the presence of an associated intracardiac shunt the recognition of a patent ductus arteriosus may not be possible even by means of...

Previous work showed that in the adult sturgeon an intrapericardial, nonmyocardial segment is interposed between the conus arteriosus of the heart and the ventral aorta. The present report illustrates the ontogeny of this intermediate segment in Acipenser naccarii. The sample studied consisted of 178 alevins between 1 and 24 days posthatching. They were examined using light and electron microsc...

OBJECTIVE To identify clinical and echocardiography predictors of the spontaneous closure of patent ductus arteriosus in preterm neonates. METHODS Sixty-one consecutive preterm neonates (gestational age 30+/-2 weeks, birth weight 1.2+/-0.2 kg) were evaluated by echocardiogram on their third day of life and those with patent ductus arteriosus were selected for a prospective cohort. Echocardiog...

A seven-week-old infant with aortic origin of the right pulmonary artery and patent ductus arteriosus is reported. During preoperative studies, a balloon catheter was used to occlude the ductus arteriosus in order to define the status of the pulmonary vascular bed. Corrective operation was performed by anastomosis of the anomalous right pulmonary artery to the main pulmonary trunk and ligation ...

The rare anomaly of a right aortic arch, distal origin of the left subclavian artery, and posterior left ductus arteriosus (forming a vascular ring) plus a right ductus arteriosus is described in an infant with d-transposition of the great arteries with an intact septum. The presence of a right aortic arch and distal left subclavian artery with bilateral ductus arteriosus has not been described...

Truncus arteriosus (TA) is a rare cardiac anomaly constituting less than 1% of all congenital heart defects. The association of complete atrioventricular septal defect (AVSD) and truncus arteriosus is uncommon. The management of this uncommon combination of lesions has not been well characterized and there is limited surgical options for treatment of these patients. We present our case report o...

The increased survival of small neonates with hyaline membrane disease has led to an increase in patent ductus arteriosus in such neonates. Durirng the period of this study patent ductus arteriosus occurred in 21 % of all newborn infants who weighed <2500 g, and were seen at this hospital; the proportion increased with decreasing birthweight and gestational age.1 Patent ductus arteriosus often ...

Objective: Patent ductus arteriosus is associated with multiple complications and high neonatal mortality. This study aimed to evaluate the efficacy benefits of paracetamol compared ibuprofen indomethacin, non-steroidal anti-inflammatory drugs usually used close in premature newborns. Data source: We searched PubMed, SciELO, Lilacs, Bireme, ClinicalTrials.gov Embase databases for articles publi...

proximity of the vagus nerve to a patent ductus arteriosus (pda) can cause traction or entrapment of vagus nerve during surgical closure of the in rare occasions. this can lead to a life threatening postoperative bradycardia. herein, we report a case of bradycardia caused by unexpected irritation of the vagal trunk by the end of operation. the patient was managed by re-opening the chest, lung r...

now-a-days truncus arteriosus has been known as “common arterial trunk” (cat) and is an uncommon congenital cardiac defect presenting in about 1-3% congenital heart disease. environmental and genetic factors effects on incidence of cat and other conotruncal anomalies. the majority patients with cat and 22q11 deletion have other anomalies such as hypoplasia or aplasia of the thymus or parath...
