Coarctation of the aorta (CoA or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. (wikipedia.org)
Preductal coarctation results when an intracardiac anomaly during fetal life decreases blood flow through the left side of the heart, leading to hypoplastic development of the aorta. (wikipedia.org)
Postductal coarctation is most likely the result of the extension of a muscular artery (ductus arteriosus) into an elastic artery (aorta) during fetal life, where the contraction and fibrosis of the ductus arteriosus upon birth subsequently narrows the aortic lumen. (wikipedia.org)
Some children born with coarctation of the aorta have additional heart defects, such as aortic stenosis, ventricular septal defect, patent ductus arteriosus or mitral valve abnormalities. (wikipedia.org)
In cases of more severe coarctations, babies may develop serious problems soon after birth because not enough blood can get through the aorta to the rest of their body. (wikipedia.org)

Ductus arteriosus6
citation needed] There are three types of aortic coarctations: Preductal coarctation: The narrowing is proximal to the ductus arteriosus. (wikipedia.org)
This spectrum is dichotomized by the idea that aortic coarctation occurs in the aortic arch, at or near the ductus arteriosus, whereas aortic stenosis occurs in the aortic root, at or near the aortic valve. (wikipedia.org)
95% of the lesions are located distal to the left subclavian artery and proximal to the ductus arteriosus (preductal coarctation) or just at or distal to the ductus (postductal coarctation). (wikidoc.org)
Thus, in utero and before the patent ductus arteriosus (PDA) closes, much of the cardiac output bypasses the coarctation via the PDA. (msdmanuals.com)
Case of coarctation1
A procedure called a lateral thoracotomy is a common approach for an uncomplicated case of coarctation. (dukehealth.org)
Diagnosis1
The diagnosis of coarctation generally can be made on the basis of physical examination. (medscape.com)
If the neonate does not have a patent ductus and is critically ill, then an emergency cardiac catheterization procedure to stretch up the coarctation with a balloon may be necessary to allow the neonate to recover before surgical repair can be safely performed. (congenital.org)
Hypertension4
BACKGROUND: Patients with repaired coarctation are at increased risk of hypertension and cardiovascular disease despite successful repair. (ox.ac.uk)
To longitudinally assess the evolution of plasma renin reactivity in relation to blood pressure in neonatally-induced coarctation hypertension, we have made serial observations in 6 coarcted dogs and in 7 littermate controls over 1-12 months post-aortic-banding during varied steady-state sodium intake. (elsevierpure.com)
We conclude that circulating modifiers of the renin reaction play no role in the genesis or in the first-year maintenance of neonatally-induced coarctation hypertension. (elsevierpure.com)
VENTRICULAR SEPTAL1
Aortic coarctation accounts for 5%-8% of all congenital heart defects and may occur as an isolated defect or in combination with ventricular septal defect and bicuspid aortic valve. (logicalimages.com)
Hypoplastic1
In a baby with a coarctation, the aortic arch also might be smaller than usual ( hypoplastic ). (kidshealth.org)
Patients7

Severe3
If the narrowing is severe enough, the left ventricle may not be strong enough to push blood through the coarctation, thus resulting in a lack of blood to the lower half of the body. (wikipedia.org)
therefore severe coarctation can be life-threatening. (wikipedia.org)

Babies1
The arch may be small in babies with coarctations. (wikipedia.org)
Infolding of the aortic1
Congenital coarctation resulting from an infolding of the aortic media that incorportaes ductal tissue, forming a ridge that eccentrically narrows the lumen of the vessel. (wikidoc.org)
On the other hand, a coarctation occurring after the left subclavian artery will produce synchronous radial pulses, but radio-femoral delay will be present under palpation in either arm (both arm pulses are normal compared to the delayed leg pulses). (wikipedia.org)
Symptoms2
Symptoms may be absent with mild narrowings (coarctation). (wikipedia.org)
Sometimes the coarctation is minor and might not even cause symptoms. (kidshealth.org)
Patient1

People with aortic coarctation often have a harsh-sounding murmur that can be heard underneath the left collar bone or from the back. (medlineplus.gov)
So now we have the left side having even more pressure than before and coarctation can be its own isolated defect but sometimes it also involves a VSD. (khanacademy.org)
Humans1
Characteristic rib changes that are seen in humans with coarctation were not apparent in this dog. (avmi.net)
The gradient across the coarctation changed from 22±10 mmHg to 6±6 mmHg, while the minimal lumen diameter increased from 9±6 mm to 15±3 mm. (pcronline.com)
