Aortic root replacement for annuloaortic ectasia with a single coronary artery

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Cardiac Anatomy

Background:

• A single coronary artery originating from the left sinus of Valsalva is an extremely rare congenital anomaly.
• This anomaly is often associated with other complex cardiac pathologies, including bicuspid aortic valve and annuloaortic ectasia.
• Surgical management of such complex cases presents unique challenges due to aberrant anatomy.

Observation:

• The case involved a patient with a single coronary artery, bicuspid aortic valve regurgitation, and significant dilation of the ascending aorta extending to the aortic arch.
• The patient presented with symptoms necessitating surgical intervention for aortic root and ascending aorta pathology.
• Accurate pre-operative assessment was crucial for planning the complex surgical approach.

Findings:

• Successful surgical correction was achieved through aortic root replacement and total aortic arch replacement.
• The single coronary artery was successfully reimplanted into the aortic root, requiring meticulous attention to the coronary orifice.
• Postoperative computed tomography (CT) confirmed the successful reconstruction of the aorta from the annulus to the arch and patency of the reimplanted coronary artery.

Implications:

• This case highlights the feasibility of complex aortic reconstruction in patients with rare coronary anomalies.
• Successful reimplantation of a single coronary artery is critical for myocardial perfusion and long-term patient outcomes.
• The findings underscore the importance of detailed anatomical understanding and surgical expertise in managing intricate congenital cardiovascular diseases.
