A case of aortic stenosis above the aortic valves (stenosis aortae supravalvularis)

In cardiac pathology, stenoses usually occur in one or other of the four main orifices of the latter, namely in the left or right venous orifice, or in the aortic or pulmonary artery. Sometimes, however, this rule presents exceptions. One of such cases, observed in the clinic of Prof. S.S. Zimnitsky, is discussed here.
