Summary
Surgical repair of mid-arch coarctation using hypothermic circulatory arrest and antegrade perfusion is safe and effective. This technique successfully reduced aortic pressure gradients in patients with this rare condition.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Congenital Heart Disease
Background:
- Coarctation of the aortic arch is a rare congenital heart defect.
- Surgical repair can be challenging due to the anomaly's location.
- This study focuses on a specific cohort with mid-arch coarctation.
Purpose of the Study:
- To describe the operative technique for mid-arch coarctation repair.
- To evaluate the outcomes of surgical intervention in these patients.
- To assess the safety and efficacy of hypothermic circulatory arrest with antegrade perfusion.
Main Methods:
- Six patients with mid-arch coarctation underwent surgical repair.
- Techniques included antegrade perfusion with hypothermic circulatory arrest.
- Surgical approaches varied (thoracotomy, sternotomy) based on lesion location.
- One complex reoperation utilized an ascending aorta to abdominal aorta bypass.
Main Results:
- All six patients survived the surgery with no reported cerebral or spinal cord complications.
- Mean follow-up was 3.3 years, with all patients remaining well.
- The mean resting gradient across the coarctation significantly decreased from 42 mmHg to 6 mmHg (p=0.0004).
Conclusions:
- Hypothermic circulatory arrest with antegrade ascending aortic perfusion is a safe and effective method for repairing mid-arch coarctation.
- Ascending-to-abdominal aortic bypass is a viable option for complex reoperations.
- The described approach leads to significant and sustained reduction in aortic pressure gradients.
