Transthoracic echocardiography revealed a severe supravalvular aortic stenosis (SVAS) with a peak Doppler velocity of 6.04 cm/s and an estimated mean pressure gradient of 89 mm Hg, with moderate aortic and mitral regurgitation. Contrast‐enhanced computed tomography (CCT) indicated a partial hourglass‐shaped narrowing of the ascending aorta. The Coanda effect, the tendency of a jet stream to adhere to a wall, was investigated as an explanation of the unequal pressures in the upper extremities in patients with supravalvular aortic stenosis (SVAS). Of 56 patients with SVAS reviewed, 48 had unequal blood pressures in the upper extremities. The average difference was 18 mm Hg systolic. The surgical treatment of severe supravalvular aortic stenosis by conventional, asymmetrical, one point patch aortoplasty across the narrowed area has been associated with a substantial incidence of residual stenosis and reoperations. A 51 year old man was referred for investigation of presumed valvar aortic stenosis. A murmur had been noted as a child but he had developed normally and was entirely asymptomatic. He had had two episodes of infective endocarditis successfully treated medically in 1968 and 1977. He was currently on no medication. Annual echocardiography had shown a possible bicuspid aortic valve with a AORTIC STENOSIS TYPES OF AORTIC STENOSIS 1.

Williams syndrome (WS) is a developmental disorder affecting connective tissue and the central nervous system. A common feature of WS, supravalvular aortic stenosis, is also a distinct autosomal
both the pathophysiology of congenital supravalvular aortic stenosis and the literature regarding sudden death in association with sedation and anesthesia. Recommendations as to preoperative assessment and management of these pa-tients are made based on the best available evidence. (Anesth Analg 2008;107:1848–54) S aortic valve wasalso observed. Discussion Supravalvular aortic stenosis may assume one of threeforms,namely(i) discretemembranous(2)the hour-glass or segmental, and (3) the diffuse hypo-plastic (Peterson, Todd, and Edwards, I965). The hour-glass form is the most frequent, and it is 1997. Supravalvular aortic stenosis was discrete in 25 and diffuse with involvement of the aortic arch and arch vessels in 4 patients. Additional anomalies were bicuspid aortic valve (n = 5), coarctation (n = 3), ascend-ing aortic aneurysm (n = 1), mitral valve insufficiency (n = 2), pul-monary valvular stenosis (n = 1), and peripheral Supra-valvular aortic stenosis is a rare congenital disease that characterized by narrowing above the sinotubular junction, and causes left ventricle hypertrophy. A 12-year-old boy was admitted to our clinic with exercise intolerance, angina, and syncope complaints and with the diagnosis of supravalvular aortic stenosis. stenosis which can be removed by surgery. Keywords Elastin, supravalvular aortic stenosis, peripheral pulmonary artery stenosis, ELN Excluded diseases Supravalvular aortic stenosis (SVAS) should be differentiated from: • valvular and subvalvular aortic stenosis which occur at the aortic valve or below the aortic valve, respectively.
Supravalvular aortic stenosis is a congenital obstructive narrowing of the aorta just above the aortic valve and is second most common type of aortic stenosis. It is often associated with other cardiovascular anomalies and is one of the characteristic findings of Williams syndrome. The diagnosis can be made by echocardiography or MRI.

Helms had open-heart surgery at age 14 to correct a severe congenital heart defect, which he described as supravalvular aortic and pulmonic stenosis. The article neglects to mention many of the most common and also most serious symptoms, including: infantile hypercalcemia, systemic hypertension, urethral stenosis, diverticulosis, aortic hypoplasia, pulmunoary stenosis, coarctation of the…
