This article covers the anatomy of the heart.
Coronary arteries
- Left main coronary artery (LMCA).
- Left anterior descending coronary artery (LAD).
- Left circumflex coronary artery (LCx).
- Right coronary artery (RCA).
Less common
- Ramus intermedius - middle branch of LMCA if it trifurcates (instead of bifurcates).[1]
- Present in approx. 1/3 of patients.
Obscure terms
- Plica transversae aortae = between aortic root & reflection pericardium.[2]
- Vincula aortae (fold of Rindfleisch) = aorta & pulmonary artery attachment, site of rupture.[3]
- Central fibrous body = fibrotic tissue that forms the membranous septum and part of the LVOT.[4]
- The AV node lies adjacent to it. There is case report suggesting, if the AV node is found within the central fibrous body, it may lead to sudden death.[5]
Left ventricle vs. right ventricle
- Left ventricle.
- Smooth outflow tract.
- Right ventricle.
Others
- Trabeculae carneae. (???)
- Semilunar valve attachment. (???)
