# Right and Left Coronary and Conus Arteries Originating from Three Separate Ostia in the Right Valsalva Sinus in a Japanese Cadaver: A Case Study with Literature Review

## TL;DR

A rare case of three coronary arteries originating from the same sinus in a Japanese cadaver was discovered during dissection.

## Contribution

This case study reports a rare coronary artery anomaly with implications for cardiac surgery and catheterization.

## Key findings

- The right, left coronary, and conus arteries originated from the right Valsalva sinus.
- The left coronary artery passed through the aorta and pulmonary artery.
- The branching patterns of the LCA and RCA were normal despite the anomalous origin.

## Abstract

A rare case of an anomalous location of the orifice of the coronary artery was found in a 99-year-old male cadaver undergoing routine dissection. The presence of the right coronary artery (RCA), left coronary artery (LCA), and conus artery (conus branch) originating from the right Valsalva sinus are the characteristic findings of this case. Then, the LCA passed through the aorta and the pulmonary artery. The LCA and RCA branches were normal. These findings are useful for future surgical procedures, including cardiac catheterization.
