Flashcards in CARDIOVASCULAR- Anatomy Deck (13):
1

Who supplied SA and AV nodes?

By Right Coronary artery

2

What can an infarct of the right coronary cause?

Nodal dysfunction (bradycardia or heart block)

3

Who is responsable of right dominant circulation?

85% Posterior descending/ interventricular artery

4

Posterior descending/ interventricular artery responsible of right dominant ciculation is a branch of this artery

Right coronary artery

5

Who gives 8% of left dominant circulation? and from whom is a branch?

Posterior descending/ interventricular artery arises from Left Circumflex artery

6

Responsable of Codominant circulation? Which percentage?

Posterior descending/ interventricular artery arises from Left Circumflex artery and Right coronary artery

7

Where is the most common site of coronary artery occlusion?

Left anterior descending artery

8

When does coronary blood flow peaks?

In early diastole

9

This is the most posterior part of the heart

Left atrium

10

What can Left atrium enlargement cause?

Dysphagia (due to compression of the esophagus) or hoarseness (due to compression of the left recurrent laryngeal nerve, a branch of the vagus)

11

Which walls are supllied by Left circumflex artery?

Lateral and posterior walls of left ventricle

12

Which structures are supllied by Left anterior descending artery?

Supplies anterior 2/3 of interventricular septum, anterior papillary muscle and anterior surface of left ventricle

13

This is what Posterior descending/ interventricular artery supplies

Posterior 1/3 of interventricular septum and posterior walls of ventricles
