An Extremely Rare Presentation of Four Coronary Anomaly Patterns Originating from the Right Coronary Sinus

Area of Science:

• Cardiology
• Congenital Heart Disease
• Medical Imaging

Background:

• Congenital coronary artery anomalies (CAAs) are rare, affecting less than 1% of the population.
• Common CAAs include separate origins for the left circumflex (LCX) and left anterior descending (LAD) arteries, and the LCX arising from the right coronary artery (RCA).
• Treatment strategies for CAAs range from coronary artery bypass grafting (CABG) to medical management.

Observation:

• An 85-year-old male presented with acute coronary syndrome.
• Diagnostic workup revealed a unique combination of four distinct coronary anomalies.
• These included left main coronary artery (LMCA) atresia, a small LAD originating posteriorly from the right coronary cusp, an anomalous LCX arising from the RCA, and an anomalous LAD originating from the LCX.

Findings:

• This case represents the first reported instance of four concurrent coronary anomalies in a single patient.
• The patient's complex anatomy presented diagnostic and therapeutic challenges.
• The coexistence of LMCA atresia with multiple other anomalies is exceptionally rare.

Implications:

• Accurate diagnosis of CAAs requires thorough imaging and potentially stress testing.
• Management of patients with multiple CAAs necessitates a tailored approach.
• This case underscores the variability and complexity of congenital coronary artery anomalies and the need for individualized patient care.
