Photomicrographs of the ascending aorta (a-c) and aortic valve (d) in the patients described in this report. Degeneration of the aorta with significant medial destruction and changes in smooth muscle orientation are observed in addition to accumulation of mucopolysaccharides and collagen deposition (a × 50 and b × 200, hematoxylin and eosin stain). Fragmentation and loss of elastic lamellae are observed across large areas of the media (c, elastica van Gieson stain × 200). Mucoid degeneration of the aortic valve is clearly visualized (d, hematoxylin and eosin stain × 200)
