Subvalvular Aortic Stenosis.
Subvalvular aortic stenosis (SAS) is a congenital heart defect that causes fixed form of hemodynamically significant left ventricular outflow tract (LVOT) obstruction with progressive course. It has a spectrum of anatomy. It appears usually beyond infancy, causes left ventricular hypertrophy and myocardial dysfunction, and tends to involve the aortic and mitral valves in its progressive course....
متن کاملFluid dynamics of aortic stenosis: subvalvular gradients without subvalvular obstruction.
Analysis of a tapering, pulsatile flow field predicts that substantial subvalvular pressure gradients exist in patients with valvular aortic stenosis (AS) without invoking a second anatomic site of obstruction. Using a catheter with two laterally mounted micromanometers, we examined the left ventricle in 11 patients with AS, mean age 64 +/- 11 years (+/- SD); the mean valve area was 1.0 +/- 0.3...
متن کاملEchocardiographic findings in discrete subvalvular aortic stenosis.
Echographic features of three patients with discrete subvalvular aortic stenosis are presented. These include a narrowed area of the left ventricular outflow tract just below the aortic valve cusps in all cases. A high-intensity but thin echo was seen in the high left ventricular outflow tract at the level of the mitral annulus in one patient with a subaortic diaphragm. In one of the three pati...
متن کاملSurgical relief of diffuse subvalvular aortic stenosis.
CONGENITAL valvular aortic stenosis and congenital localized subvalvular aortic stenosis are commonly encountered, easily recognized at operation, and relieved by standard surgical technics. Idiopathic diffuse subvalvular aortic stenosis is uncommon and can be overlooked at operation. Its relief by indirect methods has been proposed by some because of the problems inherent in its exposure in di...
متن کامل[Subvalvular aortic stenosis associated with 8p23 deletion].
We report the case of a 35-year-old man admitted due to heart failure, who had had moderate cognitive deficit, craniofacial dysmorphism, epilepsy, panic attacks and congenital heart disease (subvalvular aortic stenosis) associated with chronic atrial fibrillation since childhood. In view of his facial dysmorphism and clinical presentation, karyotype analysis was performed and revealed a de novo...
