To delineate the prevalence of cardiac findings in hypermobile and classic Ehlers-Danlos syndrome and provide longitudinal analysis of aortic root growth.

Study Design:
A retrospective chart review was conducted, and data were analyzed for cross-sectional prevalence of aortic dilation and valvular anomalies. The clinical implications of aortic root growth were determined by assessment of progression of aortic root measurements over time and clinical symptoms.

Patients whose first echocardiogram was obtained in late childhood or adulthood were less likely to have aortic dilation (P < .002) than those whose first echocardiogram was obtained in early childhood. Longitudinally, seven individuals had dilated aortas before age 14, and only one individual continued to show dilation after age 14 (P = .0143). No patient with a normal aortic root in childhood had development of dilation in adulthood. Fifteen of the 252 patients (6.0%) had mitral valve prolapse (MVP), although only one patient (0.4%) had MVP that was mild to moderate.

Although aortic root size and MVP are increased in patients with these types of Ehlers-Danlos syndrome, they tend to be of little clinical consequence. Echocardiography may still be warranted as part of cardiovascular assessment, but decreased frequency of screening is recommended especially in symptom-free adults.
