Summary
Extra-anatomic bypass surgery is a viable treatment for adult aortic coarctation, showing excellent survival and good long-term results. This surgical option can be safely combined with other cardiac procedures.
Area of Science:
- Cardiovascular Surgery
- Adult Congenital Heart Disease
Background:
- Aortic coarctation often requires surgical repair in childhood.
- Undiagnosed adult cases necessitate alternative treatment strategies.
Purpose of the Study:
- To evaluate surgical outcomes of adult patients with aortic coarctation treated with an extra-anatomic aorto-aortic bypass.
- Assess survival rates and reintervention needs in this patient cohort.
Main Methods:
- Retrospective study of 8 adult patients undergoing intrapericardial extra-anatomic bypass (2013-2021).
- Data collected on clinical characteristics, operative risk (EuroSCORE II), concurrent procedures, and follow-up outcomes up to March 2024.
Main Results:
- All patients were male, average age 39.9 years, all hypertensive.
- No operative mortality; mean follow-up 107.1 months with 100% survival.
- One reintervention required for aortic stenosis 118 months post-surgery.
Conclusions:
- Intrapericardial extra-anatomic bypass is a safe and effective treatment for adult aortic coarctation.
- This approach yields excellent short- and long-term outcomes.
- It can be successfully combined with other cardiac surgical procedures.
