Subaortic (Type 6) Muscular Band—Innocent Bystander or Pathologic Structure?
Intraventricular tendons are structures that was identified more than a hundred years ago. It has been suggested that they represent intracavitary radiations of the bundle of His and that they may be an isolated finding or be associated with structural cardiac abnormalities.Loukas et al divided these structures into five categories and recently a sixth type have been added.Various physiological...
متن کاملMuscular Subaortic Stenosis
Left ventricular ejection time was correlated with the intraventricular pressure gradient in 35 cases of muscular subaortic stenosis in which simultaneous aortic and left ventricular pressure recordings were available. Ejection times were corrected for heart rate by dividing them by the square root of the cycle length. There was a direct relation between the degree of prolongation of the ejecti...
متن کاملThe Electrocardiogram in Muscular Subaortic Stenosis
FOLLOWING Brock's' recognition that hypertrophied muscle in the left ventricular outflow tract could obstruct left ventricular outflow, much interest has centered on the nature of this hypertrophy. Initial reports suggested that concentric hypertrophy of the left ventricle was the underlying cause of the obstruction of the outflow tract. -3 Following Teare's4 description of asymmetrical hypertr...
متن کاملPropranolol in management of muscular subaortic stenosis.
Muscular subaortic stenosis (Wigle, Heimbecker, and Gunton, 1962) is one of the names used to describe functional ventricular obstruction which simulates aortic valve stenosis. Other workers (Brock, 1957, 1959; Teare, 1958; Morrow and Braunwald, 1959; Brent et al., 1960; Brockenbrough, Braunwald, and Morrow, 1961; Goodwin et al., 1960) have also emphasized the functional nature of the myocardia...
متن کاملIdiopathic ventricular septal hypertrophy causing muscular subaortic stenosis.
D ISCRETE, fixed supravalvular, valvular, and subvalvular forms of aortic stenosis are well recognized clinical entities. In 1957, Brock1 first drew attention to the fact that hypertrophied left ventricular musculature could also lead to obstruction of the left ventrieular outflow tract. He termed this "functional obstruction of the left ventricle" or "acquired aortic subvalvar stenosis." One o...
