Coronary artery bypass graft in an isolated single coronary ostium with triple vessel disease

Area of Science:

• Cardiology
• Congenital Heart Disease
• Vascular Anomalies

Background:

• Single coronary artery (SCA) is a rare congenital anomaly with an incidence of 0.0024-0.066% in patients undergoing coronary angiography.
• It is typically an isolated finding, often detected incidentally during diagnostic procedures.
• The Lipton classification system is commonly used for categorizing SCA.

Observation:

• This report details a rare case of SCA, specifically type RII-B.
• The patient presented with acute myocardial infarction, indicative of severe triple vessel disease.
• Diagnosis was confirmed through advanced imaging modalities.

Findings:

• The patient with SCA type RII-B required surgical intervention.
• Coronary artery bypass grafting was performed due to the severity of the coronary artery disease.
• This case underscores the complexity that can arise when SCA is associated with other coronary pathologies.

Implications:

• SCA, though rare, can present with significant cardiovascular complications.
• Accurate classification and diagnosis are crucial for appropriate patient management.
• This case emphasizes the importance of considering complex coronary artery disease in patients with congenital coronary anomalies.
