[Aortic regurgitation with stenosis due to congenitally bicuspid valve with fibrous band: a surgical case report].

A 62-year-old man with aortic regurgitation and stenosis underwent aortic valve replacement. Intraoperative findings showed fibrous band between the edge of the raphe and the ascending aorta. Such fibrous bands are usually observed in juvenile pure aortic valve regurgitation due to congenitally bicuspid valve with degenerative change and are related to cause aortic insufficiency. The present patient was comparatively old, and the aortic regurgitation was combined with stenosis, which revealed sclerotic change on histological examination.
