Mid left anterior descending coronary artery originating from the right coronary artery
1Department of Cardiology, Soroka University Hospital, Beer-Sheva, Israel.
Insights
Dual coronary artery connection is a rare congenital anomaly. This report details two unique cases of the left anterior descending artery connecting to the right coronary artery, one via the infundibular artery, a previously undescribed variation.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Anatomical Variations
Background:
- Congenital anomalies of the coronary arteries are rare but can have significant clinical implications.
- The dual connection of the left anterior descending coronary artery (LAD) to both the left and right coronary arteries is exceptionally uncommon.
Observation:
- This report presents two cases with an unusual dual connection of the LAD.
- In both cases, the mid-LAD connected to the right coronary artery (RCA).
- One connection was direct, while the second involved an infundibular artery.
Findings:
- The study describes a rare congenital anomaly involving the dual supply of the left anterior descending coronary artery.
- Two distinct cases are detailed, highlighting variations in the connection to the right coronary artery.
- A novel connection of the mid-LAD to the infundibular artery is reported for the first time.
Implications:
- These findings expand the known spectrum of coronary artery anomalies.
- Understanding such rare variations is crucial for accurate diagnosis and surgical planning.
- Further research may elucidate the embryological origins and clinical significance of these anomalies.
Abstract:
Dual connection of the left anterior descending coronary artery to the left and right coronary arteries is a very rare congenital anomaly. In this report we describe two cases in which the mid-position of the left anterior descending coronary artery is connected to the right coronary artery, one directly and the second by way of the infundibular artery. To the best of our knowledge, connection of the mid-position of the left anterior descending to the infundibular artery has not been previously described.
