Peds Cardiac Flashcards
congenital heart dz –> CXR –> eval which structures? (2)
- pulm vasculature
- heart size
congenital heart dz –> CXR –> eval pulm vasc –> 3 types?
- increased pulm venous flow
- increased arterial flow
- decreased arterial flow
congenital heart dz –> CXR –> pulm vasc –> increased pulm venous flow –> imaging appearance?
peripheral 1/3 –> indistinct vessels & septal markings
congenital heart dz –> CXR –> pulm vasc –> increased pulm venous flow –> can be seen in what conditions? (4)
- hypoplastic L heart
- aortic coarctation
- congestive heart failure
- neonatal sepsis
congenital heart dz –> CXR –> pulm vasc –> increased arterial flow –> imaging appearance?
peripheral 1/3 –> distinct lrg-caliber vessels
congenital heart dz –> CXR –> pulm vasc –> increased pulm arterial flow –> can be seen in what conditions? (4)
L-to-R shunt:
- atrial septal defect
- VSD
- patent ductus arteriosus
- endocardial cushion defect (AV canal defect)
congenital heart dz –> CXR –> pulm vasc –> decreased arterial flow –> imaging appearance?
peripheral 1/3 –> decreased vasculature
congenital heart dz –> CXR –> pulm vasc –> decreased pulm arterial flow –> can be seen in what conditions? (2)
RV outflow tract insuff:
- Tetralogy of Fallot
- Ebstein anomaly
increased pulm venous flow –> aka?
pulm edema
extra-cardiac AV shunt –> 2 examples? (2)
- vein of Galen malformation
- infantile hepatic hemangioma
neonatal CHF –> etiology? (2)
- primary cardiac anomaly
- extra-cardiac arteriovenous shunt
endocardial cushion defect (AV canal defect) –> assoc synd? (1)
Down synd
congenital heart dz:
- increased pulm venous flow
- increased arterial flow
- decreased arterial flow
cyanotic vs acyanotic?
- increased pulm venous flow: acyanotic
- increased arterial flow: acyantoic
- decreased arterial flow: cyantoic
congenital heart disease:
- decreased pulm vasc
- cardiomeg
what condition? (2)
- Ebstein anomaly
- pulm atresia w intact septum
congenital heart disease:
- decreased pulm vasc
- normal heart size
what condition?
Tetralogy of Fallot
congenital heart disease:
- increased pulm vasc
- normal heart size
what condition? (5)
5 Ts:
- transposition of great arteries
- truncus arteriosus
- tricuspid atresia
- total anomalous pulm venous return (TAPVR)
- single ventricle
hypoplastic L heart –> spectrum of anomalies –> which L heart struct can be involved? (5)
- LA
- LV
- mitral valve
- aortic valve
- aorta
hypoplastic L heart –> fatal –> unless have what condition?
R-to-L shunt:
- patent ductus arteriosus
- ASD
- patent foramen ovale
what is ductus arteriosus? natural progression after birth?
short connection bw proximal left pulmonary artery and aortic arch –> blood bypass the non-ventilated lungs in the fetus
after birth –> decrease prostaglandins & decrease pulm art pressure –> ductus close 2 days after birth –> blood into pulm vasculature –> ligamentum arteriosum
hypoplastic L heart –> tx?
Norwood procedure
what is Blalock-Taussig shunt?
graft –> connect R subclavian A –> R pulm A
what is bidirectional Glenn shunt?
SVC connect to R pulm A
what is modified Fontan?
tunneled conduit –> connect IVC –> pulm A
neonatal CHF –> 2 MCC?
- vein of Galen malformation
- hepatic hemangioendothelioma
ASD –> RtoL or LtoR shunt?
L-to-R
ASD –> when present?
later childhood - early adult
ASD –> assoc condition? (1)
Holt-Oram synd
Holt-Oram synd –> synd? (2)
- ASD
- UE bone deformity (ie absence/hypoplasia thumb)
ASD –> MC type? MOA?
ostium secundum
septum secundum –> incompletely cover ostium secundum
ASD –> 2nd MC type? MOA?
ostium primum
septum primum –> incompletely fuse to endocardial cushion
sinus venosus ASD –> assoc condition?
anomalous pulm venous drainage
ASD –> what structure(s) is enlarged?
RA –> RV –> pulm A
VSD –> when present?
1mo
VSD –> 2 types of location?
- # 1 membranous
- muscular IV septum
VSD –> possible complication?
Eisenmenger synd
what is Eisenmenger synd?
pulm HTN –> reversal of shunt direction
VSD –> R or L heart is enlarged?
L
