Aortic intramural coronary artery in three hearts with transposition of the great arteries
Insights
This study identified a rare aberrant coronary artery in three hearts with transposition of the great arteries. This coronary anomaly, originating abnormally, has significant diagnostic and surgical implications.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Disease
- Cardiac Anatomy
Background:
- Transposition of the great arteries is a complex congenital heart defect.
- Coronary artery anomalies can occur in patients with congenital heart disease.
- Aberrant coronary arteries pose diagnostic and surgical challenges.
Purpose of the Study:
- To describe a rare aberrant coronary artery configuration in transposition of the great arteries.
- To discuss the diagnostic and surgical implications of this specific coronary anomaly.
Main Methods:
- Examination of three hearts with transposition of the great arteries.
- Detailed external and internal inspection of coronary artery origins and pathways.
Main Results:
- An aberrant coronary artery coursed between the aortic and pulmonary roots, embedded in the aortic wall.
- The aberrant coronary orifice was located in the posterior sinus or an ectopic high position.
- The abnormal artery appeared as a separate vessel at its usual origin site.
Conclusions:
- This rare coronary arterial configuration requires careful consideration during surgical planning for transposition of the great arteries.
- Accurate identification of aberrant coronary arteries is crucial for preventing intraoperative complications.
Abstract:
Three hearts with transposition of the great arteries had an aberrant coronary artery coursing between the aortic and pulmonary roots. This coronary artery remained embedded in the aortic wall for some distance. In each case, on external inspection, the abnormal artery presented as a separate vessel at the site from which it usually originates in the left sinus of Valsalva. Internal inspection showed that in two cases the aberrant coronary orifice was in the posterior sinus, intimately related to the commissure between the left and posterior sinuses. In the third case the orifice was in an ectopic high position above this commissure. Diagnostic and surgical implications of this rare coronary arterial configuration are discussed.
