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 کاملEpidemiology and cardiovascular risk factors of aortic stenosis
The abnormalities of aortic valve morphology and function represent the most common cardiac-valve lesion particularly in elderly. The etiology of aortic stenosis is degenerative-calcific in the majority of patients. Many risk factors seems to be linked to the calcification and the stenosis of the aortic valve but they must be confirmed. In this review the etiology and the possible physiopatholo...
متن کاملAssessment of Aortic Stenosis Severity by Cardiovascular Magnetic Resonance
Cardiovascular magnetic resonance (CMR) has become a valuable tool to corroborate aortic stenosis (AS) severity when echocardiography assessment is discordant. Moreover, CMR can provide useful complementary information about AS severity and hemodynamic markers. In particular, the use of advanced 4D flow CMR allows a comprehensive assessment of complex flow alterations produced by AS. This revie...
متن کاملtatins in Aortic Stenosis
egenerative aortic stenosis is the valve lesion in which our nderstanding of pathophysiology is most advanced. Deenerative changes in the aortic valve increase with age but o not inexorably lead to stenosis (1). Degenerative aortic tenosis has many similarities to atherosclerotic plaque istologically, and has many similar predisposing risk factors 2,3). Genetic factors also play a role, and spe...
متن کاملAortic Stenosis
The report from Belgium (1) and the accompanying editorial from Sweden (2) complain, rightly, that the published indications for intervention for asymptomatic severe aortic stenosis are in conflict. American guidelines (3) require a valve area 1 cm and a mean gradient 40 mm Hg, whereas Otto et al. (4) required a peak velocity 4 m/s that predicts a gradient of 64 mm Hg. The European guidelines (...
