title: [Aortic insufficiency and septal hypertrophy in a boy with Down's syndrome].
abstract: A 9-year-old boy with Down's syndrome and aortic regurgitation. In this patient bicuspid aortic valve and rheumatic fever could not be proved. On echocardiography, basal septal hypertrophy with significantly protrusion into the left ventricular outflow tract was observed. It could explain the aortic regurgitation by ejection flow eccentrically directed to right coronary cuspid, causing a jet lesion.
