A 39-year-old woman with a history of Alport syndrome was admitted to our hospital for heart failure due to severe aortic regurgitation. Computed tomography revealed a chronic type A aortic dissection that required valve-sparing aortic root replacement. The pathological examination demonstrated that elastic fibers in the tunica media of the aortic wall are torn and severely disorganized. Immunostaining showed fragmented alpha 5 chains, indicating Alport syndrome. These findings imply Alport syndrome may have connective tissue vulnerability, rendering patients susceptible to the development of aortic disease at a young age.
Keywords: aortic dissection; aortic root replacement; aortic valve repair.
