coronary arteries and veins

Question 1

small cardiac vein

Answer 1

• located along the inferior border of the heart and w/in R coronary sulcus
• drains R atrium and ventricle

Question 2

LCA (where it comes from and branches)

Answer 2

• branch of ascending aorta located posterior to pull. trunk and anterior to L auricle
• branches:
  
  • anterior interventricular artery
  • circumflex branch of LCA

Question 3

SA nodal

Answer 3

• supplies SA node

Question 4

L posterior ventricular vein

Answer 4

• located on the posterior surface of the L ventricle

- drain L ventricle

Question 5

posterior inter ventricular artery

Answer 5

• located w/in posterior inter ventricular sulcus
• supplies posterior part of R and L ventricles and posterior part of inter ventricular septum
• in L dominant heart: posterior inter ventricular artery branches off of the circumflex branch of the LCA

Question 6

L marginal artery

Answer 6

• located of L border of heart

- supplies L ventricle

Question 7

L marginal vein

Answer 7

• located on L border of heart

- drains L ventricle

Question 8

lateral branch of LCA

Answer 8

supplies anterior part of L ventricle

Question 9

coronary sinus (location and tributaries)

Answer 9

• located in posterior coronary sulcus
• drains into R atrium
• tributaries
  
  • great cardiac vein
  • L marginal vein
  • L posterior ventricular vein
  • middle cardiac vein
  • small cardiac vein

Question 10

AV nodal

Answer 10

• supplies AV node

- may also be a branch of the LCA in L dominant heart

Question 11

anterior interventricular artery

Answer 11

• located in anterior inter ventricular sulcus
• supplies anterior part of R and L ventricles and anterior part of inter ventricular septum
• branch
  
  • lateral branch of LCA

Question 12

anterior cardiac veins

Answer 12

• drain into R atrium
• cross over R coronary artery in the coronary sulcus
• drain anterior R ventricle and atrium

Question 13

RCA (where it comes from and branches)

Answer 13

• branch of ascending aorta located within R coronary sulcus b/n R atria and R ventricle
• branches:
  
  • SA nodal
  • R marginal artery
  • posteror interventricular artery
  • AV nodal

Question 14

R marginal artery

Answer 14

• located on inferior border of heart

- supplies R ventricle

Question 15

middle cardiac vein

Answer 15

• located w/in posterior inter ventricular sulcus

- drains posterior L and R ventricles, and posterior part of the inter ventricular septum

Question 16

great cardiac vein

Answer 16

• located w/in anterior inter ventricular sulcus and L coronary sinus
• drains anterior L and R ventricles, anterior part of the interventicular septum and L atrium

Question 17

circumflex branch of LCA

Answer 17

• located in L and posterior coronary sulcus
• supplies L atrium and L ventricle
• branch
  
  • L marginal artery
