Supernumerary right coronary artery
Insights
A rare supernumerary right coronary artery with two separate origins from the right sinus was identified. This unique anatomical variation, the first reported in English literature, details the branching patterns of both vessels.
Area of Science:
- Cardiovascular Anatomy
- Coronary Artery Anomalies
Background:
- Anatomical variations of the coronary arteries can impact cardiac function and surgical planning.
- Supernumerary coronary arteries are rare congenital anomalies.
Observation:
- A unique case of a supernumerary right coronary artery originating from two separate ostia in the right coronary sinus is presented.
- The smaller vessel supplied the sinoatrial nodal branch and posterior descending artery.
- The larger vessel supplied the conus branch, right ventricular branches, and acute marginal branch.
Findings:
- Detailed description of a dual-origin supernumerary right coronary artery.
- First reported case of this specific anatomical variation in the English literature.
- Characterization of the distinct branching patterns of the two originating vessels.
Implications:
- Highlights the importance of detailed coronary artery imaging for identifying rare anomalies.
- Contributes to the anatomical knowledge base for cardiovascular research and clinical practice.
- May inform surgical approaches and risk assessment in patients with coronary artery variations.
Abstract:
A rare case of a patient with supernumerary right coronary artery in whom the two vessels arose from the right coronary sinus from two separate ostia adjacent to each other is presented. The smaller vessel gave off the sinoatrial nodal branch and the posterior descending artery whereas the larger one gave off the conus branch, the right ventricular branches, and continued as acute marginal branch. This is the first case report in the English literature.
