Summary
A rare congenital coronary artery anomaly originating from the aorta was identified in a patient with angina. Percutaneous transluminal coronary angioplasty (PTCA) successfully treated significant stenosis in the right coronary artery, relieving symptoms.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Interventional Cardiology
Background:
- Coronary artery anomalies are rare congenital conditions that can predispose individuals to myocardial ischemia.
- Atypical coronary artery origins require detailed anatomical assessment for accurate diagnosis and management.
- Angina pectoris and positive exercise tests are common clinical presentations necessitating coronary angiography.
Observation:
- A 45-year-old patient presented with angina and a positive exercise test.
- Coronary arteriography revealed an anomalous origin of the left coronary artery from a vascular structure connecting the aorta to the mid-left anterior descending artery.
- Significant (90%) stenosis was identified in the right coronary artery.
Findings:
- The patient underwent percutaneous transluminal coronary angioplasty (PTCA) to address the right coronary artery stenosis.
- Post-procedure, the patient remained asymptomatic at an eight-month follow-up.
- The identified left coronary artery anomaly appears to be unique, with no similar cases documented in existing literature.
Implications:
- This case highlights the importance of recognizing and characterizing rare coronary artery anomalies.
- Successful intervention for associated coronary artery disease in the presence of anomalous coronaries is feasible.
- Further investigation into the clinical significance and long-term outcomes of such rare anomalies is warranted.
