Intramural coronary artery as a cause of unstable angina pectoris
Southern Medical Journal
|October 1, 1978
Insights
An anomalous intramyocardial course of the left anterior descending (LAD) coronary artery can cause angina. Surgical correction via aortocoronary artery bypass can provide symptomatic relief and improve exercise tolerance.
Area of Science:
- Cardiology
- Cardiac Surgery
- Anatomical Variations
Background:
- Intramural coronary artery anomalies are rare congenital conditions.
- These anomalies can lead to myocardial ischemia and angina pectoris.
- Symptomatic presentation necessitates evaluation for potential intervention.
Observation:
- A case report details a patient with an anomalous intramyocardial course of the LAD coronary artery.
- The patient presented with significant angina pectoris due to the anomaly.
- Medical management failed to provide adequate symptomatic relief.
Findings:
- The patient underwent successful aortocoronary artery bypass surgery.
- Post-operative assessment revealed complete symptomatic relief from angina.
- Improved exercise tolerance was noted following surgical intervention.
Implications:
- Intramural coronary arteries, though rare, can be clinically significant.
- Surgical correction is a viable option for patients with refractory symptoms.
- Intervention can lead to improved quality of life and functional capacity.
Abstract:
A patient with an anomalous intramyocardial course of the LAD coronary artery, causing angina pectoris, is described. The patient had symptomatic relief after an aortocoronary artery bypass operation. Intramural coronary arteries may be clinically significant. In cases where medical management does not provide relief, surgical correction of the anomaly may give symptomatic improvement and improved exercise tolerance.
