- The Right Coronary Artery (RCA)gives:

- Posterior interventricular artery (Posterior Descending Artery – PDA)
- This is confirmed in standard anatomy references (e.g., StatPearls, NIH, radiology sources) and also reflected in the provided material
Key Clarification
- Acute marginal artery

- Posterior interventricular artery (PDA)
- Usually arises from RCA (right-dominant circulation)
