Abstract
We report the case of an 11-year-old boy with Loeys-Dietz syndrome, with both aortic and pulmonary aneurysms requiring cardiac operation because of progressive valve incompetence resulting from loss of coaptation of the cusps. Arterial medial changes, consisting of disarray of elastic fibers and increased collagen deposition, were observed in surgical specimens from both the aorta and the pulmonary artery of our patient, and the strong pSmad2 nuclear staining of smooth muscle cells of both aortic and pulmonary tunica media are the best evidence of transforming growth factor-β pathway activation in Loeys-Dietz syndrome.
