An apical mid-diastolic murmur is sometimes audible in patients with a patent ductus arteriosus (Nadas and Alimurung, 1952) but differentiation from organic mitral stenosis is usually not difficult. The patient described in this paper presented with typical murmurs of isolated mitral stenosis and the correct diagnosis of patent ductus arteriosus and trivial mitral stenosis was made only at oper...

SUMMARY Left vocal cord paralysis in association with patent ductus arteriosus is unusual. We report a patient with long-standing patent ductus arteriosus (PDA) in whom CT studies obtained before and after paralysis developed showed an interval increase in size of the pulmonary trunk. The pathogenesis of left vocal cord paralysis in association with long-standing PDA is discussed.

The inability to differentiate accurately between patent ductus arteriosus and aortopulmonary window may occasionally result in finding an aortopulmonary window while prepared to close a patent ductus arteriosus at left thoracotomy. Anatomic and technical factors now allow aortopulmonary window closure from the left chest using surgical clips in certain selected cases. The successful repair of ...

The ductus arteriosus is a communication between the main pulmonary trunk and the descending aorta. In utero, the ductus arteriosus allows blood flow to be diverted from the high-resistance pulmonary circulation to the descending aorta and the low-resistance placental bed. Functional closure of the ductus arteriosus occurs soon after birth but can be delayed in premature infants and in certain ...

The adrenergic innervation of the patent human ductus arteriosus was studied using the Falck-Hillarp fluorescent histochemical method for the localization of monoamines. Few adrenergic terminals were demonstrated in the muscular layers of the patent ductus arteriorms in 14 specimens examined. The innervation to the adventitia was sparse to moderate. The possibility that a developmental abnormal...

Between May 2003 and July 2006, we carried out percutaneous patent ductus arteriosus closure using a Nit-Occlud device in 28 patients, who had a median age of 1.8 years (range 0.5-21 years) and a median weight of 10.9 kg (range 5.9-64 kg). The ductus arteriosus had several different morphologic forms, and there was one postsurgical recanalization of the ductus arteriosus. The median minimum duc...

BACKGROUND Several devices are available for transcatheter occlusion of patent ductus arteriosus. Most of these devices either require complicated intracardiac maneuvering, have not been tried in humans, or need a large-sized sheath for implantation of the device. METHODS AND RESULTS During a 26-month period ending November 1992, 14 patients underwent transcatheter closure of patent ductus ar...

OBJECTIVE To identify clinical and echocardiographic parameters associated with the evolution of the ductus arteriosus in neonates with birth weight lower than 1,500g. METHODS Retrospective study of 119 neonates in which clinical parameters (Prenatal: maternal age, risk of infection and chorioamnionitis, use of corticosteroid, mode of delivery and gestational age. Perinatal: weight, Apgar sco...

There are very few reports on successful management of young children with coexistence of two congenital heart defects, coarctation of aorta and patent ductus arteriosus. These lesions can be treated either simultaneously or sequentially. Herein, we present the first successful report of simultaneous balloon angioplasty and Amplatzer duct occluder device implantation in a single-sitting in an 8...

Patent ductus arteriosus (PDA) is a congenital disorder in heart, wherein the ductus arteriosus fails to close after birth. This leads to the generation of a left-to-right shunt, leading to pulmonary hypertension. Color Doppler echocardiography is essential for the diagnosis. The identification of a diastolic flow oriented in the opposite direction in the pulmonary artery finalizes the diagnosi...
