What Is Aortopathy in Congenital Heart Disease?
Aortopathy refers to disease of the aorta characterized by dilation, aneurysm formation, dissection risk, or abnormal wall composition. In congenital heart disease, aortopathy is most commonly seen in association with bicuspid aortic valve (BAV), which carries an intrinsic risk of aortic root and ascending aorta dilation independent of valve function. Coarctation of the aorta is associated with accelerated aortic stiffness, hypertension, and aortic wall abnormalities even after successful repair. Marfan syndrome, Loeys-Dietz syndrome, Turner syndrome, and other connective tissue disorders also cause aortopathy in the congenital heart population. Management requires serial imaging surveillance, blood pressure optimization, risk-stratified surgical threshold guidance, and pregnancy risk counseling.
Surveillance, Thresholds, and Pregnancy
Aortic surveillance intervals are individualized based on aortic diameter, rate of change, the presence of a bicuspid valve and its morphology, family history of aortic events, connective tissue disorder diagnosis, and symptoms. Guidelines provide aortic diameter thresholds at which elective surgical intervention should be considered — typically between 50 and 55 mm for most patients with BAV, or lower with rapid growth or family history of dissection. For women with aortopathy planning pregnancy, aortic diameter thresholds are lower than in non-pregnant patients, and the hemodynamic stress of pregnancy places additional risk on a dilated aorta. Preconception aortic assessment and counseling is a core component of our cardio-obstetric practice.
