4 heart valves |
Aortic Pulmonary Mitral Tricuspid |
|
|
Auscultation area for Aortic valve |
right 2nd intercostal space, lateral to sternum |
|
|
Auscultation area for Pulmonary valve |
left 2nd intercostal space, lateral to sternum |
|
|
Auscultation area for Mitral valve |
left 5th intercostal space, 8 cm from midline |
|
|
Auscultation area for tricuspid valve |
left 4th intercostal space, just lateral to sternum |
|
|
coronary sulcus |
separates the atria from the ventricles Also called AV groove |
|
|
Ligamentum arteriosa |
remnant of the ductus arteriosa connects and fixes the pulmonary trunk to the aortic arch |
|
|
right coronary artery branches |
Scott Cowen Motorboats Paupers Sinoatrial nodal branch Conus branch Marginal branch Posterior Interventricular |
|
|
Left Coronary Artery branches |
All Creeps Must Cry Anterior Interventricular branch Conus branch Marginal branch Circumflex branch |
|
|
Sinoatrial nodal branch |
Off right coronary artery (60% of the time) supplies the SA node in the right atrium
|
|
|
Conus branch of right coronary artery |
supplies outflow tract of right ventricle |
|
|
Marginal branch of right coronary |
courses along margin of right ventricle above diaphragm |
|
|
Posterior Interventricular branch |
key to dominance of the heart From the right coronary artery 85% of the time |
|
|
Anterior interventricular branch |
supplies walls of ventricles and major part of interventricular septum |
|
|
Conus branch of left coronary |
Supplies conus arteriosus of the ventricles (pouch in the right ventricle that gives rise to pulmonary trunk) |
|
|
Marginal branch |
branch of the circumflex artery travels along posterolateral aspect of left ventricle towards the apex |
|
|
Circumflex artery |
off left coronary artery Runs along sulcus coronarius towards back of the heart usually small, but can be big if it gives rise to the posterior IV branch |
|
|
Bundle of His |
AV bundle transmits the SA nodal impulse rapidly to the ventricles Starts at AV node and extends through ventricles close to IV septum |
|
|
Coronary veins |
Coronary sinus Great cardiac Vein Middle cardiac Vein Lesser cardiac vein Left Marginal Vein
|
|
|
Great cardiac vein |
Starts at apex of heart Ascends along Anterior IV branch of left coronary artery |
|
|
Coronary Sinus |
Runs between left atrium and left ventricle on posteroinferior surface of the heart (coronary sulcus) Mainly receives blood from great, middle, and small cardiac veins Also receives blood from left marginal vein and posterior IV vein |
|
|
Middle cardiac vein |
begins at apex of heart ascends in posterior IV groove alongside posterior IV artery |
|
|
small cardiac vein |
Accompanies the right coronary artery Drains the right atrium and ventricle |
|
|
Left marginal vein |
Drains the lateral left ventricle Empties into distal coronary sinus or great cardiac vein |
|
|
Right marginal vein |
Drains the right atrium and ventricle Joins the small cardiac vein |
