Idiopathic hypertrophic subaortic stenosis (hypertrophic obstructive cardiomyopathy) changing concepts-1975.
.1 ( HOCM ) , is one of the few common diseases virtually unknown 20 years ago. Since the early case report in 1957’ and the pathologic description in 1958,2 numerous articles have appeared, and yet the disorder ( or more accurately the spectrum of disorders ) continues to be an enigma and a source of controversy. This review will attempt to summarize some of the currently known facts and fanci...
متن کاملSubaortic and midventricular obstructive hypertrophic cardiomyopathy with extreme segmental hypertrophy
BACKGROUND Subaortic and midventricular hypertrophic cardiomyopathy in a patient with extreme segmental hypertrophy exceeding the usual maximum wall thickness reported in the literature is a rare phenomenon. CASE PRESENTATION A 19-year-old man with recently diagnosed hypertrophic cardiomyopathy (HCM) was referred for sudden death risk assessment. The patient had mild exertional dyspnea (New Y...
متن کاملCardiac impulse in hypertrophic obstructive cardiomyopathy.
A double apical impulse has been described as a physical sign in hypertrophic obstructive cardiomyopathy (Mounsey, 1959; Braunwald et al., 1960; Boiteau and Allenstein, 1961; Pare et al., 1961; Benchimol, Legler, and Dimond, 1963; Cohen et al., 1964; Gillam, Deliyannis, and Mounsey, 1964; Tafur, Cohen, and Levine, 1964). In this study we have used the impulse cardiogram, which is an optical rec...

Panel B, ventriculography of the right ventricle (RV) and left ventricle (LV), showing significant interventricular septal (IVS) hypertrophy during diastole and Panel C, LV outflow tract obstruction during end-systole.

متن کاملMuscular (hypertrophic) subaortic stenosis (hypertrophic obstructive cardiomyopathy): the evidence for true obstruction to left ventricular outflow.
The clinical and haemodynamic significance of the subaortic pressure gradient in patients with muscular (hypertrophic) subaortic stenosis (hypertrophic obstructive cardiomyopathy) has long been debated. In this report we summarize the evidence which indicates that true obstruction to left ventricular outflow exists in these patients. Rapid left ventricular ejection, through an outflow tract nar...
