Valvular aortic stenosis in pediatric age group is mostly congenital in origin. The aortic valve may be unicuspid, bicuspid, tricuspid or rarely quadricuspid. Left ventricle undergoes concentric hypertrophy secondary to obstruction to its outflow tract. In neonatal aortic stenosis, left ventricle may be hypoplastic.

The degree of obstruction in aortic stenosis ranges from mild to severe. Bicuspid aortic valve (BAV), one of the most common congenital heart diseases may be asymptomatic during childhood. BAV is identified in about 1.5% of adults. The most common level of obstruction is valvar followed by sub valvar and supravalvar stenosis.

CONGENITAL AORTIC STENOSIS [PDF]
American Journal of Roentgenology, 1966 The roentgenographic and angiocardiographic features of congenital valvular, supravalvular, and subvalvular aortic stenosis have been reviewed and described.The single most common roentgenographic finding in this group of conditions was left ventricular enlargement.

Calcific aortic stenosis (AS) is the most common form of valvular heart disease in Europe and North America. It is a progressive disease with a prolonged period of asymptomatic latency which eventually leads to critical left ventricular outflow tract obstruction necessitating surgical replacement of the valve.

Archives of Surgery, 1962
Operations under direct vision for congenital aortic stenosis began with the use of hypothermia, but since heart-lung machines have become safe, cardiopulmonary bypass is now preferred. Today these 2 modalities are combined for the benefit of both patient and surgeon.

Aortic stenosis (AS) is a common valve disorder in an ageing population in western countries, and women, with longer life expectancy, comprise a substantial percentage of elderly patients with AS. Compared with men, women exhibit distinctive characteristics at the level of stenotic valve leaflets and subsequent compensatory responses of the left ...
