Coronary artery bypass in a patient with single anomalous right coronary artery

Area of Science:

• Cardiology
• Vascular Surgery

Background:

• Coronary artery anomalies (CAAs) are congenital conditions affecting coronary artery anatomy.
• The prevalence of CAAs in the general population is not well-established.
• Atherosclerotic coronary artery disease (CAD) is a common condition, but its association with CAAs is rare.

Observation:

• A 57-year-old male patient presented with symptoms suggestive of coronary artery disease.
• Diagnostic imaging revealed a single coronary artery anomaly.
• The patient also had significant atherosclerotic plaque burden in the coronary arteries.

Findings:

• The patient underwent successful coronary artery bypass surgery (CABS).
• This case highlights the successful surgical management of CAD in the context of a rare coronary artery anomaly.
• The association between atherosclerotic CAD and single coronary artery is uncommon but manageable.

Implications:

• This case contributes to the limited literature on managing atherosclerotic CAD in patients with single coronary artery.
• It underscores the importance of thorough pre-operative evaluation for coronary artery anatomy in patients undergoing revascularization.
• Further research is needed to understand the true incidence and clinical implications of CAAs.
