Aortic supravalvular stenosis is the least common form of aortic obstruction and affects both sexes equally. Aortic supravalvular stenosis may be due to the presence of: a discrete fibrous membrane, an hour-glass narrowing, or a diffuse narrowing. 6-8 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.

Background Supravalvular aortic stenosis (SVAS) is the rarest form of left ventricular outflow tract (LVOT) obstruction and there is no agreement on the optimal management strategy for these patients
Aortic valve stenosis (AVS) is a congenital aortic defect in which the aortic lumen narrows due to thickening or (other synonyms: valvular aortic stenosis, aortic valve disease) 2003; https://www.orpha.net/data/patho/GB/uk-SVAS.pdf. 8. Congenital supravalvular aortic stenosis is due to a variety of anomalies in the proximal portion of the ascending aorta. Clinically, however, the most importan. Hypoplasia of ascending aorta.

All patients had associated cardiac malformations (one atrial and two ventricular septal defects, one supravalvular aortic stenosis and one quadricuspid Abstract The objective of this paper is to describe the novel four-patch technique [modified Brom's] for repair of supravalvular aortic stenosis (SVAS).

Of these four defects, supravalvular mitral membrane (SVMM) is the first to occur, and triggers the development of the other three defects.[ citation needed] Partial complexes, or forme fruste, have also been described.

valve first, so that rheumatic aortic valve disease is accompanied by rheumatic mitral valve changes. Subvalvular or supravalvular stenosis is distinguished from.
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 Congenital supravalvular aortic stenosis is due to a variety of anomalies in the proximal portion of the ascending aorta. Clinically, however, the most important lesion is a circular constriction of the aortic wall above the valve cusps. In certain patients with this type of anomaly, the 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). The condition is described as supravalvular because the section of the aorta that is narrowed is located just above the valve The present study describes a large family with a high frequency of supravalvular aortic stenosis including five generations and 80 subjects, the largest family group with this disease studied so far. Aortic stenosis is most commonly caused by age-related progressive calcification (>50% of cases), with a mean age of 65 to 70 years. Another major cause of aortic stenosis is the calcification of a congenital bicuspid aortic valve (30-40% of cases), typically presenting earlier (ages 40+ to 50+). Download as PDF. Set alert. About this page. Supravalvular aortic stenosis is a rare condition in which the level of obstruction is above the aortic valve in the ascending aorta. It has classically been described in association with Williams syndrome (elfin facies, peripheral pulmonary artery stenosis, coarctation of the aorta, and Download with Google Download with Facebook TECHNIQUE _____ Bentall Procedure for an Adult Patient with Supravalvular Aortic Stenosis and Coronary Aneurysms Haitham Alzahrani, M.D., Mostafa Al-Shamiri, M.D., Hanan AlBackr, M.D., Bakir M.
