CT angiography images of an anomalous right coronary artery

Area of Science:

• Cardiology
• Congenital Heart Disease
• Medical Imaging

Background:

• Coronary artery anomalies are relatively uncommon congenital heart defects.
• Anomalous origin of the right coronary artery from the contralateral sinus of Valsalva can lead to myocardial ischemia.
• Symptoms often include angina pectoris, particularly during exertion.

Observation:

• A 33-year-old male presented with angina pectoris.
• Conventional coronary angiography revealed an abnormal origin of the right coronary artery from the left aortic cusp.
• High-resolution CT angiography precisely delineated the anomalous vessel's course between the ascending aorta and main pulmonary artery.

Findings:

• The patient had a rare coronary artery anomaly: right coronary artery originating from the left aortic cusp.
• High-resolution CT angiography provided detailed anatomical information crucial for surgical planning.
• Surgical transposition of the anomalous coronary artery was performed successfully.

Implications:

• This case highlights the importance of advanced imaging techniques like CT angiography in diagnosing complex coronary artery anomalies.
• Successful surgical management can lead to complete symptom resolution in patients with this condition.
• Understanding and treating such anomalies are vital for preventing adverse cardiovascular events.
