Surgery for congenital diseases of the aorta

Area of Science:

• Cardiology
• Genetics
• Vascular Surgery

Background:

• Congenital aortic diseases manifest as obstructive lesions in infancy or aneurysms in later life.
• Aneurysmal presentations are often linked to connective tissue disorders and repaired conotruncal heart defects.

Purpose of the Study:

• To review the evolving indications for intervention in congenital aortic aneurysms.
• To differentiate management strategies for aneurysms associated with specific genetic syndromes versus post-surgical dilation.

Main Methods:

• Literature review focusing on congenital aortic diseases, connective tissue disorders, and surgical interventions.
• Analysis of age- and lesion-dependent factors influencing treatment decisions.

Main Results:

• Indications for intervention in aortic aneurysms are dynamic and depend on patient age and specific aortic lesion.
• Conditions like Loeys-Dietz syndrome and Turner syndrome may warrant aggressive prophylactic surgery.
• Marfan syndrome also requires consideration for prophylactic intervention, albeit potentially less aggressive.

Conclusions:

• Management of congenital aortic aneurysms is evolving, with a need for individualized, age- and lesion-specific treatment plans.
• Aggressive surgical approaches may be beneficial for patients with Loeys-Dietz syndrome, Turner syndrome, and to a lesser extent, Marfan syndrome.
• Aortic dilation following repair of congenital heart lesions generally follows a more benign course and warrants conservative management compared to de novo aneurysms.
