Cardiology Flashcards
Differential Cyanosis
post-ductal; cyanosis of lower extremities (toes)
ex: aortic arch obstruction, R->L shunt
Reverse Differential Cyanosis
Pre-ductal, cyanosis of fingers
TGA
S4 in children, differential
AS, HOCM, MR
TR associated with
Ebstein Anomaly
Peripheral Pulmonary Stenosis
increase in blood flow to lungs via pulmonary artery
SEM, back and axilla
Venous Hum
blood draining from collapsed jugular veins into dilated intrathoraic veins
low pitched murmur, absent when supine
Innocent Murmur and position
increase when supine (increase in stroke volume)
softer w/ Valsalva
Aschoff Bodies
giant cells seen in heart associated with RF
ARF - 5 Jones Criteria
polyarthirtis carditis chorea subq nodules erythema marginatum
Carditis associated with ARF
Mirtral regurg
Myocarditis
Pericarditis
Erythema Marginatum appearance
serpiginous
Chronic treatment of ART
PCN for minimum of 5 years or until age 21
Most common cardiomyopathy in children
dilated
ASD - Ostium Secondum
Most Common
Fixed Splitting + RVOT
RVOT across pulmonic valve = SEM, best heard at LUSB
EKG associated w/ ASD
RAD, RVH
except, primum = LAD
ASD - Ostium Primum
partial AV canal defect, MR and TR
LVH on EKG =
tall R + negative T wave in V6
Anomalous Origin of Left Coronary Artery from Aorta
chest pain w/ exercise or SCD
when aorta dilates during exercise, cuts off blood supply to coronaries
Most common cause of cyanosis in first days of life =
TGA
d-TGA anatomy
pulmary artery connected to LV
Aorta connected to RV
need some type of connectin (PFO, PDA, VSD)
