Summary
A rare single coronary artery anomaly can lead to severe ischemia and sudden death risk. This case highlights successful surgical intervention for a patient with this condition.
Area of Science:
- Cardiology
- Congenital Heart Disease
Background:
- Congenital single coronary artery anomalies are rare but can present with significant cardiovascular risks, including myocardial ischemia and sudden cardiac death.
- Patients with this anomaly may remain asymptomatic or present with atypical symptoms, complicating diagnosis.
Observation:
- A 54-year-old male presented with exertional chest pressure, a hypotensive response during stress testing, and perfusion defects on nuclear imaging, indicating severe ischemia.
- Coronary angiography revealed a rare single coronary artery anomaly, with the right coronary artery originating from the left main, alongside high-grade stenoses in the left anterior descending and circumflex arteries.
Findings:
- The patient exhibited severe ischemic changes despite minimal symptoms and electrocardiographic alterations during stress testing.
- Diagnostic workup confirmed a single coronary artery anomaly with significant obstructive coronary artery disease and moderate aortic regurgitation.
Implications:
- This case underscores the importance of comprehensive cardiac evaluation in patients with suspected or confirmed single coronary artery anomalies.
- Surgical revascularization and aortic valve replacement can effectively manage complex cases, improving outcomes and mitigating risks associated with this anomaly.
