ABSTRACT
Williams syndrome is a congenital disorder characterized by mental retardation, loquacious personalities, dysmorphic face, and vascular and valvular abnormalities. The etiology of this syndrome was one allelic loss of elastin gene, exhibiting a submicroscopic deletion, at 7q11.23. Sudden death is an infrequently recognized complication. The mechanism of sudden death is explained by myocardial ischemia, decreased cardiac output, and arrhythmia by anatomical abnormality of coronary artery stenosis and severe biventricular outflow tract obstruction. We report an autopsy case of a 80 day-old male with Williams syndrome. Five days before admission, cardiac murmur was detected incidentally on ascultation at a local clinic during a visit for vaccination. He was transferred to our hospital and cardiac catheterization was done. He died suddenly next day. Postmortem examination revealed a dysmorphic face and multiple cardiovascular abnormalities including supravalvular aortic stenosis with narrowed coronary artery ostia, supravalvular pulmonic stenosis, secundum type of atrial septal defect, right ventricular hypertrophy, and renal artery stenosis. Histologically, aorta and pulmonary, bronchial, and renal arteries showed markedly hyperplastic medial elastic laminae approximately three times thick compared to those of age-matched normal artery. The elastic fibers of the innermost two thirds of media were disposed in a normal orderly parallel fashion. In outer third of the media, the elastic fibers had lost the normal orderly arrangement.
Key Words: Williams syndrome; Elastin gene; Hyperplastic elastic lamina
