Posterior pericardial ascending-to-descending aortic bypass: an alternative surgical approach for complex coarctation...

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Congenital Heart Disease

Background:

• Coarctation of the aorta often presents with recoarctation or other cardiovascular issues requiring intervention.
• The optimal surgical strategy for complex coarctation remains debated.
• Posterior pericardial ascending-to-descending aortic bypass graft (CoA bypass) facilitates simultaneous intracardiac repair.

Purpose of the Study:

• To evaluate the safety and efficacy of CoA bypass via median sternotomy in patients with complex coarctation.
• To assess outcomes including morbidity, mortality, and graft patency.

Main Methods:

• Retrospective review of 18 patients undergoing CoA bypass between 1985 and 2000.
• Patients had complex coarctation, often with prior interventions and concomitant cardiovascular conditions.
• Surgical approach involved median sternotomy with posterior pericardial bypass graft.

Main Results:

• All 18 patients survived the operation with patent grafts at a mean follow-up of 45 months.
• No graft complications, stroke, or paraplegia were reported.
• Significant reduction in systolic blood pressure from 159 mmHg to 125 mmHg.

Conclusions:

• CoA bypass via median sternotomy is associated with low morbidity and mortality.
• This extra-anatomic bypass is an effective single-stage solution for complex coarctation or recoarctation with concurrent cardiovascular disorders.
