CARDIOVASCULAR- Anatomy Flashcards
Who supplied SA and AV nodes?
By Right Coronary artery
What can an infarct of the right coronary cause?
Nodal dysfunction (bradycardia or heart block)
Who is responsable of right dominant circulation?
85% Posterior descending/ interventricular artery
Posterior descending/ interventricular artery responsible of right dominant ciculation is a branch of this artery
Right coronary artery
Who gives 8% of left dominant circulation? and from whom is a branch?
Posterior descending/ interventricular artery arises from Left Circumflex artery
Responsable of Codominant circulation? Which percentage?
Posterior descending/ interventricular artery arises from Left Circumflex artery and Right coronary artery
Where is the most common site of coronary artery occlusion?
Left anterior descending artery
When does coronary blood flow peaks?
In early diastole
This is the most posterior part of the heart
Left atrium
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)
Which walls are supllied by Left circumflex artery?
Lateral and posterior walls of left ventricle
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
This is what Posterior descending/ interventricular artery supplies
Posterior 1/3 of interventricular septum and posterior walls of ventricles
