Supravalvular aortic stenosis (SVAS) is rare in twins. We report monozygotic twins, both of whom had SVAS, coronary ostial stenosis, and peripheral pulmonary arterial stenosis, but no other phenotypic features of Williams syndrome. One of the twins died suddenly, but the SVAS and the right and left coronary ostial stenoses were enlarged successfully at operation in the other twin.
瓣上主动脉狭窄（SVAS）在双胞胎中较为罕见。我们报告了一对单卵双胞胎，两人均患有SVAS、冠状动脉口狭窄和周围肺动脉狭窄，但无威廉姆斯综合征的其他表型特征。其中一名双胞胎突然死亡，但另一名双胞胎在手术中成功扩大了SVAS以及左右冠状动脉口狭窄。
