Aortic root replacement with absent left-main coronary artery: how to do it

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Aortic Surgery

Background:

• Aortic root replacement presents unique challenges in patients with concomitant coronary artery anomalies.
• Annuloaortic ectasia and coarctation of the aorta are complex conditions requiring specialized surgical approaches.
• Coronary artery anomalies, such as an absent left main coronary artery, necessitate careful pre-operative planning and intra-operative modifications.

Observation:

• The patient presented with annuloaortic ectasia and coarctation of the aorta.
• A significant coronary anomaly was identified: an absent left main coronary artery with separate origins for the left anterior descending and left circumflex coronary arteries from the aorta.
• Standard aortic root replacement techniques required modification to accommodate the anomalous coronary artery anatomy.

Findings:

• Successful aortic root replacement was performed despite the complex anatomy.
• Technical modifications were employed to ensure adequate coronary artery perfusion during and after the procedure.
• The patient's post-operative course was uneventful, demonstrating the feasibility of this approach.

Implications:

• This case highlights a viable surgical strategy for aortic root replacement in patients with complex coronary artery anomalies.
• It underscores the importance of detailed anatomical assessment and tailored surgical techniques in managing challenging cardiovascular cases.
• The findings contribute to the body of knowledge on managing patients with combined aortic and coronary pathologies.
