Angiocardiography in congenital subvalvular aortic stenosis: prognosis and operative indications
JC Hoeffel, L Gengler, M Henry and C Pernot
Twenty-three patients with congenital subvalvular aortic stenosis are
reviewed. The importance of classifying this stenosis into four types based
on angiocardiographic findings is stressed, as are the indications for left
heart catheterization during the preoperative and postoperative course of
the disease. The type of congenital subvalvular aortic stenosis should be
an important consideration during the discussion of operative indications
in both asymptomatic and symptomatic patients.
