CP Angiology Flashcards

What is the anatomical name for the LAD
Anterior interventricular artery
Which major coronary artery (right or left) does more to supply the conductance system of the heart?
What branch of that major artery is so vital?
The left coronary artery
Anterior interventricular artery (LAD)
Which side has the brachiocephalic trunk?
What comes off of the brachiocephalic trunk.?
The right side.
Right common carotid and right subclavian arteries.
What artery does the anterior intercostal artery come off of?
Internal thoracic
What are the two terminal arteries of the internal thoracic artery?
Which one is medial, and which one is lateral?
Musculophrenic (lateral)
Superior epigastric (medial)
What are the three sources of blood to the mammary gland?
Lateral mammary A. (from lateral thoracic)
Medial mammary A. (from internal thoracic)
Lateral cutaneous branch of the posterior intercostal arteries.
What vessel do the right and left bronchial arteries come off of?
The thoracic aorta.
They are the “paired lateral visceral branches”
What three arteries supply the diaphram?
Musculophrenic (internal thoracic)
Pericardiophrenic (internal thoracic)
Superior phrenic (descending thoracic aorta)
What cardiac vein empties directly into the right atrium without passing through the coronary sinus?
Anterior cardiac veins
What vein runs with the posterior interventricular artery?
Middle cardiac vein
What two arteries run with the great cardiac vein?
Circumflex artery
Anterior interventricular artery
What vein can run with the right marginal artery?
Small cardiac vein
What are the branches of the Right Coronary A. ?
Sinuatrial Nodal A. (SA node)
Conus Branch (Conus Arteriosus)
Atrial Branch (RA)
Right Marginal a. (inferior border)
Atrioventricular Nodal a. (to AV node)
Posterior Interventricular A. (gives off interventricular septal branches)
Right posterolateral A. (LV)
(See CAR At PIeR)
What are the branches of the Left Coronary A.
Anterior interventricular A. (AV bundle, conduction, most blood)
Conus branch
Lateral A.
Interventricular Septal branches
Circumflex A. giving off Left Marginal A. and Posterior Left Ventricular A.
CN: Coronary Artery Bypass Graft
Obstruction of the coronary arteries may necessitate replacement of a segment of the coronary artery.
Great Saphenous V. is normally used, can use radial A. also
CN: Coronary Angioplasty
Insertion of a small balloon catheter into the lumen of the coronary artery
Balloon is inflated to flatten the obstructing plaque against the wall and increase the size of the lumen, improving blood flow
What are the branches of the Internal Thoracic A.
Anterior Intercostal A. giving off
- Perforating branches (to the breast)
- Medial Mammary branches (to the breast)
Pericardiacophrenic A. (pericardium and diaphragm)
Musculophrenic A. (terminal branch)
Superior Epigastric A. (terminal branch
What does the axillary artery supply that is related to breast arterial supply?
axillary artery gives off lateral thoracic A. which gives off Lateral Mammary branches to the breast
What are the three types of branches that can come off of the Descending Aorta?
Unpaired Visceral Branches
Paired Lateral Visceral Branches
Paired Segmental Parietal Brances
Bonus! Superior Phrenic A.
What are the branches from the Unpaired Visceral Branches?
Mediastinal A.
Esophageal A.
Pericardial A.
(good luck seeing any of them)
What are the branches of the Paired Lateral Visceral Branches?
Right Bronchial A.
Left Bronchial A.
(Tricky to find in Lab, but do it.)
What are the branches of the the Paired Segmental Parietal Branches?
Posterior Intercostal A. giving off
- Dorsal Branch
- Collateral branch (along with intercostal N. collateral)
- Lateral Cutanous A. (skin) and gives off Lateral Mammary branches to breast
Subcostal A.
What are the branches of the Pulmonary Trunk?
Right Pulmonary A.
Left Pulmonary A.
What are the branches of the Right Pulmonary A.
Superior Lobar A.
Middle Lobar A.
Inferior Lobar A.
One to each lobe of the r. lung.
