A 12-year-old boy with ventricular septal defect and patent ductus arteriosus was presented to the operating room. Upon clamping the patent ductus arteriosus, the femoral arterial pressure curve was lost; however, it returned upon unclamping. Upon further dissection, an interrupted aortic arch was found between the left subclavian artery and patent ductus arteriosus. The surgery was discontinue...

OBJECTIVE The purpose of this study was to evaluate the hemodynamic changes in left ventricular function before and after patent ductus arteriosus ligation in premature infants with regard to the energetic efficiency of left ventricular pumping. METHODS Thirty-five premature infants who underwent patent ductus arteriosus ligation were enrolled in this study. Left ventricular efficiency was ev...

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...

BACKGROUND The most common congenital heart disease in the newborn population, patent ductus arteriosus, accounts for significant morbidity in preterm newborns. In addition to prematurity and environmental factors, we hypothesized that genetic factors play a significant role in this condition. OBJECTIVE The objective of this study was to quantify the contribution of genetic factors to the var...

Simultaneous transcatheter coil occlusion of patent ductus arteriosus and balloon angioplasty of coarctation of aorta is avoided since intimal tearing after angioplasty is believed to increase the risk for dissection of the aorta during catheter manipulation. We report a 14-month-old boy, with weight of 7.6 kg, with aortic coarctation and patent ductus arteriosus with a large left-to-right shun...

Two premature infants who had surgical ligation of their patent ductus arteriosus are described. These infants initially did well postoperatively but then developed congestive heart failure. Both infants had echocardiographic evidence of recurrence of their patent ductus arteriosus. One of the infants required a repeat ligation procedure. It is important to continue to monitor premature infants...

The patent ductus arteriosus was first described by Galen. No thought was given to the surgical treatment of patients with persistently patent ducti until 1907, when Munro described a technique for their ligation. It was not until twenty-one years later that Gross of Boston successfully ligated a patent ductus arteriosus for the first time. Since the epochal operation by Gross increased attenti...

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...

Patent ductus arteriosus (PDA) is an open communication between the upper descending thoracic aorta and the proximal left pulmonary artery, which results from persistence of the fetal ductus arteriosus. It may be isolated or occur with other congenital cardiac anomalies. Aneurysms of the ductus arteriosus are rare lesions which may occur as a spontaneous. infantile fonn or occur in later c...
