Endovascular treatment of coarctation and related aneurysms

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Medicine

Background:

• Surgical repair of coarctation of the aorta (CoA) significantly improves survival, with most patients reaching adulthood.
• Late complications of CoA repair include hypertension, ventricular dysfunction, and potentially life-threatening aortic aneurysms.
• Observation of CoA-related aneurysms carries a high mortality (36%), while surgical repair has a 9% mortality rate.

Purpose of the Study:

• To evaluate endovascular treatment as an alternative for CoA-related aneurysms.
• To assess the safety and efficacy of endograft implantation for these complex cases.
• To compare endovascular treatment outcomes with traditional surgical repair.

Main Methods:

• Review of endovascular treatment using endografts for post-CoA repair aneurysms.
• Analysis of intermediate outcomes, morbidity, and mortality associated with endograft procedures.
• Comparison of endovascular outcomes against historical data for surgical repair and observation.

Main Results:

• Endovascular treatment with endografts is a successful alternative to reoperative surgery for CoA-related aneurysms.
• This approach demonstrates lower morbidity and mortality rates compared to surgical repair.
• Excellent intermediate outcomes and minimal complications were observed with endograft implantation.

Conclusions:

• Endovascular repair with endografts is a safe and effective option for managing aortic aneurysms following coarctation of the aorta repair.
• It offers a reduced risk profile compared to reoperative surgery.
• The choice of specific endograft depends on patient anatomy, availability, and surgeon preference.
