Key result
Roentgenography and angiocardiography demonstrated left ventricular enlargement as the most common finding across congenital valvular, supravalvular, and subvalvular aortic stenosis.
Why the study?
What are the roentgenographic and angiocardiographic features of different types of congenital aortic stenosis?
What are the roentgenographic and angiocardiographic features of different types of congenital aortic stenosis?
Different types of congenital aortic stenosis present with distinct roentgenographic features, such as poststenotic dilatation in valvular stenosis and left atrial enlargement in subvalvular stenosis, which can be well demonstrated by selective angiocardiography.
LV enlargement predominates on historical imaging across congenital aortic stenosis subtypes; leaves open whether modern modalities enhance type-specific diagnosis.
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. Poststenotic dilatation of the ascending aorta was frequently discernible on the roentgenograms of the chest of patients having congenital valvular stenosis, but it was not detected in patients having isolated supravalvular or subvalvular stenosis. Left atrial enlargement was common in subvalvular stenosis, was infrequently encountered in valvular stenosis, and was not detectable in any cases of supravalvular stenosis. The pathologic anatomy of the various types of congenital aortic stenosis was well demonstrated in all instances by means of large-film biplane selective angiocardiography.

Takekawa et al. (1966) conducted a review in Congenital aortic stenosis. Roentgenography and angiocardiography was evaluated on Roentgenographic and angiocardiographic features. Roentgenography and angiocardiography demonstrated left ventricular enlargement as the most common finding across congenital valvular, supravalvular, and subvalvular aortic stenosis.
