systemic venous stenoses but then was extended to the treatment of aortic coarctation
This was then followed by application of stent technology to the pediatric population (1,2). The technique was initially used to treat branch pulmonary artery and systemic venous stenoses but then was extended to the treatment of aortic coarctation. In this issue of JACC: Cardiovascular Interventions, Mohan et al. (12) evaluate the feasibility and effectiveness of stent implantation to treat aortic coarctation in young children and compare the results with those in older children. Stent therapy seems to be an attractive and preferred alternative to surgical or balloon therapy for treatment of aortic coarctation in the adolescent and young adult.
Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level. It typically gets worse over time. Symptoms often come on gradually with a decreased ability to exercise often occurring first. If heart failure, loss of consciousness, or heart related chest pain occur due to AS the outcomes are worse.

The primary physiologic effect of coarctation of the aorta and aortic stenosis is impedence of blood flow out of the . With time, both defects progressively worsen, and may require surgical intervention in the teenage or adult years.
The primary physiologic effect of coarctation of the aorta and aortic stenosis is impedence of blood flow out of the left ventricle, producing left ventricular strain. If unchecked, this progresses on a continuum leading to left-sided failure. Patients are asymptomatic in their younger years. While early and late postoperative results are quite good, these patients with obstructive lesions need continued medical and nursing follow-up throughout their adult years.

Pulmonary arterial stenosis may be caused by postsurgical scarring after . It may manifest in the neonatal period with sudden cardiovascular collapse at 7 to 10 days of age when the ductus arteriosus closes
Pulmonary arterial stenosis may be caused by postsurgical scarring after palliation or repair of congenitally malformed hearts, as in tetralogy of Fallot, a distally migrated pulmonary arterial band, or after the LeCompte manoeuvre as part of an arterial switch operation. As with other obstructive lesions, peripheral pulmonary artery stenosis reduces vascular cross sectional area, increasing ventricular impedance, resulting in a progressive pressure load on the corresponding ventricle. It may manifest in the neonatal period with sudden cardiovascular collapse at 7 to 10 days of age when the ductus arteriosus closes. Coarctation in later infancy and childhood is possible.

Although aortic coarctation was the most common indication for initial intervention (61%), adult interventions occurred predominantly for . Heart failure as a result of stenotic valvar heart disease in the young adult is rare.
Although aortic coarctation was the most common indication for initial intervention (61%), adult interventions occurred predominantly for aortic valve/left ventricular outflow tract (60%) and mitral valve (33%) lesions. Conclusions: Shone complex is an under-recognized entity associated with relatively low mortality in adulthood but substantial morbidity related to arrhythmias, heart failure, and interventions.

Coarctation (ko-ahrk-TAY-shun) of the aorta - or aortic coarctation - is a narrowing of the aorta, the large blood vessel that branches off your heart and delivers oxygen-rich blood to your body. When this occurs, your heart must pump harder to force blood through the narrowed part of your aorta. In addition, if the coarctation of the aorta is severe, your heart might not be able to pump enough blood to your other organs. This can cause damage to your heart and also can result in kidney failure or other organ failure.

There are three common ones - pulmonic or pulmonary stenosis in which the pulmonary valve is abnormally formed and consequently, the right ventricle is usually hypertrophied, it has a much bigger workload, and often, the blood flow into the lungs is reduced. If this is very severe, it has to be dealt with in very early childhood, often with a balloon catheter that dilates up the pulmonic valve.
