An echocardiogram would be needed to definitively

An echocardiogram would be needed to definitively diagnose valvular aortic stenosis.
This would not only provide a diagnosis but aid the clinician in assessing the degree of
hypertrophy of the left ventricular wall. According to Huether, & McCance, (2012) the
physiological consequence of severe aortic stenosis is hypertrophy of the left ventricular wall,
which then may lead to increased end-diastolic pressure, which in turn causes hypertension in the
pulmonary arteries and veins.
Treatment
The treatment for valvular aortic stenosis is determined by the severity of symptoms. If
discovered early the goal of treatment is often continued observation and monitoring of cardiac
function. Baloon angioplasty is not favored in children with aortic stenosis as it often results in
aortic regurgitation and these patients almost always require needing surgical valuotomies
(Huether, & McCance, 2012). The ROSS procedure is the treatment of choice in many children.
This involves replacing the stenosis aortic valve with the pulmonary valve and placing a
homograft in the place of the pulmonary valve (Huether, & McCance, 2012). The benefit of the

ROSS procedure is there is no need for anticoagulation and it defers mechanical valve
replacement as long as possible (Huether, & McCance, 2012).
