Insights
Two patients with chest pain were found to have a single coronary artery originating from the wrong sinus of Valsalva. This uncommon congenital anomaly requires careful consideration, especially if surgery is needed.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Coronary Artery Anomalies
Background:
- Patients presenting with angina symptoms require thorough diagnostic evaluation.
- Coronary arteriography is a key diagnostic tool for assessing coronary artery anatomy and stenosis.
Observation:
- Two patients with exertional angina and chest pain underwent coronary arteriography.
- Both patients were diagnosed with a single coronary artery anomaly, originating from the contralateral sinus of Valsalva.
Findings:
- A single coronary artery without significant stenosis was identified in both cases.
- This congenital coronary anomaly is uncommon but clinically significant.
Implications:
- Accurate identification of single coronary artery anomalies is crucial for surgical planning.
- The prognosis for this anomaly is generally good if unassociated with other cardiac defects.
Abstract:
One patient with chronic exertional angina, not significant electrocardiographic signs of myocardial ischemia at exercise stress test and recent onset of angina at rest underwent coronary arteriography. A second one with known severe aortic stenosis underwent cardiac catheterization and coronary arteriography because of effort chest pain and syncope. A single coronary artery originating respectively from the right and from the left sinus of Valsalva but without significant coronary stenosis was detected in both patients. This entity is a quite uncommon finding of relevant interest if surgical treatment is required and good prognosis if not associated with additional cardiac anomalies.
