Ramus intermedius

32

Only branch of LCX

Obtuse marginal

33

35

Supplies the acute margin of the heart or the anterior wall of the right ventricle

Acute marginal branches of RCA

36

Goes through the posterior IV groove

PDA

37

Supplies the undersurface of the heart, goes through the cardiac groove or crux from the AV node branch

Posterolateral ventricular branch

39

PDA and PLV arise from the RCA

Right dominant

40

41

If the RCA gives off the PDA, and the left main coronary artery gives off the PLV

Co-dominant

42

Blood vessels are imaged after opacification by contrast medium
Measures pressure in the heart chambers

Conventional angiography
