Overview

Coarctation of the aorta accounts for 4-7% of all congenital heart disease. While stent therapy, when feasible, is the standard of care for coarctation, it may not completely improve the work (and afterload) of the heart due to its effects on the elasticity of the aorta. This study will provide the information needed to understand the effects of current management on the cardiac mechanics and work.

Eligibility
