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 clinical and physiological characteristics of the uncomplicated patent ductus arteriosus in the adult have been well-defined and understood for many years. A typical continuous murmur usually develops early in life; the electrocardiogram is usually normal or shows a left axis deviation; and heart fluoroscopy ordinarily shows only mild to moderate left ventricular enlargement, vigorous aorti...

DESCRIPTION A premature newborn weighing 1.9 kg, presenting with cyanosis, feeding and respiratory difficulties was admitted to our centre for further evaluation. An initial echocardiogram suggested a pulmonary atresia with a malalignment infundibular ventricle septum defect with atypical right-sided ductus arteriosus (2.4 mm) arising from the aberrant right subclavian artery (4 mm), which was ...

Normal pulmonary artery pressure and pulmonary hypertension assessment of newborns is rarely reported. The aim of the study is to explore dynamic changes of pulmonary arterial pressure and ductus arteriosus in human newborns from birth to 72 h of age with echocardiography.A total of 76 cases of normal newborns were prospectively detected by echocardiography after birth of 2 h, 6 h, 12 h, 24 h, ...

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 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...

Data on the natural history of infants discharged with patent ductus arteriosus is sparse. We report on the 36-months follow-up after hospitalization in 68 infants discharged with an open ductus arteriosus. Notwithstanding a high spontaneous closure rate, catheter intervention in 5 infants illustrates a critical need for cardiologic follow-up.

Truncus arteriosus (TA) is a rare cardiac anomaly constituting less than 1% of all congenital heart defects. Its association with complete atrioventricular septal defect (AVSD) is extremely unusual and only 12 cases diagnosed postnatally or postmortem have been reported so far. We describe the first case of truncus arteriosus with AVSD to be diagnosed prenatally by fetal echocardiography.
