Aortic root replacement in a patient with previous coronary artery bypass

Area of Science:

• Cardiovascular Surgery
• Thoracic Aortic Disease
• Aortic Dissection

Background:

• Acute type A aortic dissection is a medical emergency.
• Prior cardiac surgery is a known risk factor for aortic dissection.
• Coronary artery bypass grafting (CABG) is a common cardiac procedure.

Observation:

• A rare case of late-presenting acute type A thoracic aortic dissection is presented.
• The dissection occurred four years after a three-vessel coronary artery bypass grafting.
• The patient required surgical intervention for the aortic dissection.

Findings:

• Successful surgical repair of the acute type A thoracic aortic dissection was achieved.
• The procedure involved resection of the aortic valve and aneurysmal tissue.
• Reconstruction utilized a composite graft, preserving native coronary ostia and aorto-saphenous vein graft connections.

Implications:

• This case demonstrates the feasibility of successful surgical repair for acute type A aortic dissection in patients with a history of CABG.
• Preservation of coronary arteries and bypass grafts during aortic repair is crucial for optimal outcomes.
• Highlights the importance of considering aortic pathology in patients with prior cardiac surgery presenting with relevant symptoms.
