SUPRAVALVAR AORTIC STENOSIS IN CHILDREN REPORT OF THIRTEEN CASES
During 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of Shahid Rajai Heart Hospital, Tehran. All patients were subjected to cardiac catheterization and a angiocardiography. Patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. Seventy seven percent of childen were male. Eight cases (61.5%) had Wil...
متن کاملPatterns of progression of aortic stenosis: a longitudinal hemodynamic study.
To examine factors that might affect progression in valvular aortic stenosis (AS), we reviewed serial hemodynamic studies in 50 adult patients. Seven patients had congenital, 22 rheumatic and 21 degenerative-calcific aortic stenosis. The patients with calcific aortic stenosis were older (62 ± 6 vs 51 ± 9 years, p < 0.001) and had onset of murmur later in life. For all patients average values at...
متن کاملReappraising myocardial fibrosis in severe aortic stenosis: an invasive and non-invasive study in 133 patients.
Aims To investigate myocardial fibrosis (MF) in a large series of severe aortic stenosis (AS) patients using invasive biopsy and non-invasive imaging. Methods and results One hundred thirty-three patients with severe, symptomatic AS accepted for surgical aortic valve replacement underwent cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LGE) and extracellular volume f...
متن کاملSerial hemodynamic observations in asymptomatic children with valvar aortic stenosis.
The natural history of valvar aortic stenosis in children is uncertain. This report analyzes serial clinical and catheterization data of nine initially asymptomatic children. The first hemodynamic study was performed at an average age of 6.8 years, and the follow-up study at an average age of 13.1 years. Cardiac indices and left ventricular enddiastolic pressures were consistently normal in all...
متن کاملSupravalvular aortic stenosis: clinical, hemodynamic and pathologic observations.
In 3 patients obstruction to left ventricular outflow was shown to be due to a localized narrowing of the aortic root at the point of insertion of the aortic leaflets. The site of obstruction was localized by left heart catheterization and selective angiography. The pathologic findings in 2 patients are described and the problem of the surgical management of this unusual form of aortic stenosis...
