Heart Flashcards
Landmarks for drainage of fluid in cardiac tamponade
Left 5th-6th ICS near sternum
Forms base of the heart
LA
Forms apex of heart
LV
Forms sternocostal surface of heart
RV
Produce S1
AV closure
Produce S2
Semilunar valve closure
Physiologic splitting of S2
Delayed closure of pulmonic valve on inspiration
Produce S3
Rapid flow from atriun to ventricles
Produce S4
Late diastolic filling of ventricle due to atrial contraction
Drains to the RA
SVC, IVC, Coronary sinus
Tributaries of coronary sinus
Great cardiac vein, small cardiac, middle cardiac
Blood supply of left atrium and ventricle
Circumflex branch of LCA
Supply of IV septum and apex
Anterior IV branch of left coronary
Supply right ventricle
Anterior IV art and marginal branch kf RCA
Supply right atrium
RCA
Substernal pain may be referred over the T1-5 dermatomes. Results from transient ischemia
Agina Pectoris
Most common BV involved in MI
LAD
Node located at thr junction of SVC and RA
SA node

RA
Remnant of foramen ovale
Fossa ovalis
Pectinate muscles can be found in
RA
Trabeculae Carnae and papillary muscles found in
RV
Modified trabecular carnae that crosses the IV septum
Moderator band
Most posterior chamber
LA
Embryo of root of Aorta and Pulmonary Trunk
Truncus arteriorsus

ASD
CHD with left to right shunt, LVH, pulmo htn.
VSD
Most common VSD
Membranous
CHD with failure of truncal ridges and aorticopupmo setum to develop normally. VSD always presenT and overrides VSD
TA
CHD where aorta in RA and PA in LV
Assoc with asd and vsd
