Flashcards in Congenital Heart Defects Deck (27):
1

What is worse L to R shunt or R to L shunt?

R to L shunt is worse

2

What is the most frequent congenital defect

VSD

3

What are the Left to Right shunts

VSD
ASD
PDA

4

What can uncorrected L to R shunt lead to?

Eisenmenger syndrome

--> increased pulmonary hypertension --> RVH---> R to Left shunt

late cyanosis, clubbing, polycythemia

5

Harsh Holosystolic murmur

VDA

6

Loud S1, wide fixed S2

ATrial septal defect

7

MCC of ASD

Ostium secundum defect

foramen ovale + foramun secundum overlap so don't close

8

Continuous "machine- like murmur"

PDA

9

When do you want PDA? How you make it

Transposition of great vessels
go PGE

10

Increase BP in upper extremities
Lower BP in lower extremities

Coarctation of aorta

11

Notching of Ribs

Coarctation of aorta

12

Aortic regurgitation

Coarctation of aorta

13

What are the 5 Right to Left shunts?

5T's
1. Truncus arteriosus (1 vessel)
2. Transposition (2 vessels)
3. Tricuspid atresia (3 vessels)
4. Teratalogy of Fallot (4 vessels)
5. TAPVR (5 in name)

14

What do you usualy have with a Persistant truncus arteriosus?

VSD

15

What is Tricuspi atresia?

Absence of tricuspid valve and hypoplastic RV

16

What is required for Tricuspid atresia for viability

both ASD and VSD required for viability?

17

TERATOLOGY OF FALLOT

IHOP
VSD
HYPERTROPHY OF RV
Overriding aorta
Pulmonary stenosis

18

Boot shaped heart on CSR

Kids- RVH maybe teratology of Fallot
Adults- COPD

19

If you have Teratology of fallot what improves cyanosis?

Squatting increases SVR decreases right to left shunt

but do surgery to treat

20

What is total anomalous pulmonary venous return

Pulmonary veins drains into right heart circulation (CVS, coronary sinus, etc);

associated with ASD sometimes PDA to allow for R to L shunting to maintain CO

21

MC congenital cause of early cyanosis

Teratology of Fallot

22

Chromosome 22q11 deletion

Truncus arteriosus, teratology of fallot

btw this is DiGeorge syndrome

23

Down syndrome

Endocardial cushion defect

like ASD or VSD, center of

24

Congenital Rubella

PDA or pulmonary artery stenosis

25

Turner syndrome

Coarctation of aorta, bicuspid aortic valve

26

Diabetic mom

Transposition of great vessels

27

Alcoholic exposure

VSA, PDA, ASD, teratology of Fallot
