Intraoperative angiography after coronary bypass grafting in a patient presenting with a single coronary artery: a...

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Medical Imaging

Background:

• Single coronary artery is an exceptionally rare coronary artery anomaly.
• Common anomalies requiring intervention include pulmonary origins, fistulae, and anomalous aortic origins.
• Coronary atherosclerosis often necessitates revascularization strategies.

Observation:

• A 72-year-old male presented with a single coronary artery originating from the right sinus of Valsalva and diffuse coronary atherosclerosis.
• Percutaneous coronary intervention attempts were unsuccessful in revascularizing the anomalous coronary system.
• Intraoperative angiography was utilized to assess the bypass graft's effectiveness.

Findings:

• Successful bypass grafting was performed for the anomalous single coronary artery system.
• The patient experienced complete symptom relief 6 months post-operation.
• This case highlights the viability of surgical revascularization for complex coronary anomalies.

Implications:

• Bypass grafting can be an effective treatment for rare single coronary artery anomalies when less invasive methods fail.
• Accurate intraoperative assessment is crucial for managing anomalous coronary systems.
• Further research into managing rare coronary artery anomalies is warranted.
