aortic coarctation/hypoxia

Fourteen patients 6 weeks to 8 months of age with coarctation of the aorta (CA) were examined before and after correction of the anomaly. In inspiration of increasing concentrations of O2 the TavO2 was progressively delayed below CA as compared to the region above CA, which reflected latent tissue

A previously healthy, one-year-old, intact female Vizsla dog collapsed and experienced cardiopulmonary arrest after a stressful event. Postmortem examination identified juxtaductal aortic coarctation (AoCo) with complex morphology. Located in the isthmus aorta adjacent to the ligamentum arteriosum,

OBJECTIVE To evaluate the results of covered Cheatham-Platinum stent implantation in the management of native coarctation of the aorta and report intermediate and long-term follow-up. BACKGROUND Covered stents are being used increasingly in severe and complex coarctation of the aorta mainly to

Necrotizing enterocolitis (NEC) sometimes occurs in term infants with congenital heart disease. This article reports a rare case of a term infant with coarctation of the aorta complex who developed NEC on the 8th day after birth. Spontaneous closure of the ductus arteriosus in the 1st week of life

The liver in children contains a greater amount of connective tissue in relation to parenchymal tissue than in adults and there is often more in the left than in the right lobe. Livers from 150 children who died between birth and 12 years of age, under different circumstances, were studied.The

Preeclampsia (preECL), a hypertensive disorder of pregnancy, which occurs only in humans, is dangerous for mother and fetus. It may be caused by placental hypoxia triggering the release of a circulating factor that damages the maternal endothelium leading to vasoconstriction and hypertension. Our

Between March, 1978, and April, 1982, 48 neonates under 4 weeks of age were operated upon for severe coarctation of the aorta in our unit. Of these, 36 babies were in severe congestive cardiac failure and 11 had renal failure. Angiocardiography and echocardiography demonstrated intracardiac lesions

Cells of the medullary segment of the thick ascending limb of Henle's loop (TALH) convert arachidonic acid (AA) via the cytochrome P-450 monooxygenase pathway to biologically active metabolites: P1, a vasorelaxant, and P2, an inhibitor of Na+-K+-ATPase activity. These AA metabolites may contribute

A 59-year-old man with a history of coarctation repair, mechanical aortic valve, and warfarin therapy presented with right flank pain. Computerized tomography (CT) scan showed a large hematoma encircling an intact descending thoracic aorta. CT angiogram demonstrated multiple areas of intercostal

An 11-month-old girl with an unbalanced atrioventricular septal defect, coarctation of the aorta and an interrupted inferior vena cava with hemiazygos continuation post-surgical status of coarctation repair and pulmonary artery banding underwent a Kawashima operation. Severe hypoxia occurred

In the past 2 years, eight patients have had repair of coarctation of the aorta or interrupted aortic arch along with an intracardiac procedure performed through a simple midsternotomy. Five underwent total repair and three had palliation for the intracardiac lesion. Four patients did well

BACKGROUND Recurrent stenosis after extended end-to-end anastomosis for aortic coarctation is the primary indication for further interventions in children. Tension because of the extended resection and local arterial wall hypoxia are possible pathogenetic mechanisms. We hypothesized that (1) tension

OBJECTIVE Treatment of ductus arteriosus is controversial. The merits and timing of ductus ligation versus indomethacin treatment were compared. METHODS Study parameters for infants with PDA (June 1988 through March 2001) included age, weight, physical findings, echocardiograph,

BACKGROUND Mortality rate for heart transplantation for patients with hypoplastic left heart syndrome (HLHS) has improved, but there is a considerable wait until a suitable donor is available. Thus it is important to examine the duration of survival and risk factors for early death in patients with

Electrocardiograms of marathon runners were examined to study hypertrophy of the heart due to prolonged physical exertion and to differentiate this from hypertrophy due to various disease states, especially essential hypertension, aortic valvular disease and coarctation of the aorta. The
