Pseudoaortic stenosis produced by ventricular hypertrophy

Clinical Aspects of Cardiomyopathy

“…When the septum obstructs the outflow of the left ventricle the condition simulates aortic stenosis, but has certain inmportant differences. A similar, though not necessarily identical, condition has been described by Brock (1957Brock ( , 1959, by Bercu et al (1958), by Morrow and Braunwald (1959), by Soulid et al (1959), and by Brent et al (1960). Table I, section 4, shows the patients with this condition whom we have studied.…”

“…The condition is now being widely described by various authors under different titles. Thus a clinical syndrome which is very similar has been described by Brock (1957Brock ( , 1959 with the diagnosis of " functional obstruction of the left ventricle," while Bercu et al (1958) used the term "pseudo-aortic stenosis." Morrow and Braunwald (1959) regard the condition as due to " functional aortic stenosis."…”

Hypertrophic Obstructive Cardiomyopathy

“…Since Brock's first report of the hiemodynamic and pathological findings in "functional obstruction of the left ventricle" (Brock, 1957(Brock, , 1959, and Teare's description of the pathology and clinical findings in "asymmetrical hypertrophy of the heart" (Teare, 1958), a host of publications has appeared describing this disorder, and an almost equally large number of terms has been used to describe these cases (Bercu et al, 1958;BevegArd, Jonsson, and Karlof, 1962;Boiteau and Allenstein, 1961;Brachfeld andGorlin, 1959, 1961;Braunwald et al, 1960;Brent et al, 1960;Goodwin et al, 1960;1961;Hollman et al, 1960;Menges, Brandenburg, and Brown, 1961;Moberg, Fix, and Soderberg, 1962;Morrow and Braunwald, 1959;Nordenstrom and Ovenfors, 1962;Pare et al, 1961;Shabetai and McGuire, 1963;Soulie, Joly, and Carlotti, 1962;Wigle, Heimbecker, and Gunton, 1962).…”

Obstructive Phenomena in Ventricular Hypertrophy

“…Although usually asymmetrical, the hypertrophy may be diffuse, as in Case 1, and in cases confirmed at autopsy by Bercu et al (1958) and by Pare et al (1961). Localization purely to the right ventricle, as in our Case 4, has not previously been shown.…”
