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.
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.

We described a case diagnosed clinically and genetically confirmed through aCGH. Genetic assessment identified three microdeletions with a total size of 1.35 Mb located at 7q11.23. Supravalvular aortic stenosis (SVAS) is a type of heart defect that develops before birth. It is characterized by a narrowing (stenosis) of the section of the aorta just above the valve that connects the aorta to the heart (aortic valve). From the Green Lane Hospital, Auckland, New Zealand. Facial resemblance to a patient in whom supravalvular aortic stenosis was discovered and successfully relieved at operation has led to the correct diagnosis of supravalvular stenosis in three other patients. All four patients are mentally Supravalvular aortic stenosis (SVAS) is a heart defect that develops before birth. This defect is a narrowing (stenosis) of the large blood vessel that carries blood from the heart to the rest of the body (the aorta). Supravalvular aortic stenosis is an uncommon form of aortic stenosis. This results in not only a hemodynamically significant stenosis but also distortion of the valve commissures and, consequently, abnormal aortic valve geometry and coaptation of the aortic leaflets. Supravalvular aortic stenosis is a rare congenital cardiac anomaly involving stenosis of the sinotubular junction that can extend to the ascending aorta and the aortic arch. It is an elastin arteriopathy that is classically associated with Williams syndrome. Many surgical techniques have been developed over time, most commonly involving pericardial patches to relieve the stenotic area. There are few published reports of the results of supravalvular aortic stenosis correction with the use of Brom's 3-patch technique. Herein, we report our use of this procedure and the short-term results therefrom. From 2002 through 2007, 9 children underwent surgical correction of localized
