Flashcards in Left to Right shunt Deck (53):
1

3 types of ASD

secundum defect, primum
defect, and sinus venosus defect.

2

Only defect that lies inside the fossa ovalis

Ostium Secundum Defect

3

Most common type of ASD

Ostium Secundum Defect

4

Anterior to the fossa ovalis

Ostium Primum Defect

5

this is present 10% of ostium secundum ASD

Anomalous pulmo Venous return

6

Posterior to the fossa ovalis

Sinus Venosus Defect

7

physical signs of ASD

Relatively slender body build
precordial bulge
hyperdynamic cardiac impulse

8

medical management of ASD

diuretic in infants with CHF

9

preferred method for non surgical closure

catheter delivered closure device

10

kind of murmur in ASD

systolic ejection murmur at 2nd LICS

11

most common CHD

VSD

12

location of perimembranous defects (VSD)

beneath aoritc valve, posterior to the papillary muscles

13

most common VSD

Perimembranous defects

14

location of indundibular or conal (outlet) VSSD

beneath pulmonic valve

15

outlet defect is associated with

aortic insufficiency

16

location of inlet defect

posterior and inferior to the perimembranous
defect beneath the septal leaflet of the tricuspid valve

17

location of midmuscular defect

posterior to the septal band

18

location of apical muscular defect

near the cardiac apex

19

this may be seen in ECG in those with moderate VSD

Left Ventricular Hypertrophy (QRS widening) and
left atrial hypertrophy (Notching of P wave) may be
seen

20

this may be seen in ECG in those with large VSD

Biventricular hypertrophy with or without LAH

21

these serve as markers of specific type of VSD except for trabecular defects

cardiac valves

22

when does Spontaneous closure of perimembranous and muscular
defect occur

first 6 months

23

CHF in large defect develops not until

6-8 weeks

24

This is used to assess pulmonary arteriolar resistance

cardiac catheterization

25

male to female ration of PDA

1:3

26

PDA is associated with

Low birth weight and congenital Rubella syndrome

27

if there is PVOD ___ is present in ECG

RVH

28

PDA in term infants results from

structural
abnormality of the smooth muscle rather than a
decreased responsiveness of the ductal smooth
muscle to oxygen

29

standard device used for non surgical closure for small PDA <3mm

gianturco stainless steel coils

30

Larger ductus are closed by

Amplatzer PDA device

31

weight requirement for closure using amplatzer

>6kg

32

standard procedure for surgical closure of PDA

PDA ligation and division

33

how is VATS clip ligation performed

3 small ports in the 4th ICS

34

what syndrome in right isomerism

asplenia

35

what syndrome in left isomerism

polysplenia

36

syndromes assctd with partal form of avsd

di george\
ellis van creveld

37

four types of avsd

partial defect
complete
intermediate
common atrium

38

there is a distinct and separate mitral and tricuspid annuli in this defect

partial avsd

39

primum asd and cleft mitral v

partial avsd

40

partial avsd is symptomatic with the presence of

mitral valve insufficiency

41

ecg features of partial avsd

prolonged PR interval
P-wave changes indicating L and R atrial enlargement

42

right atrial enlargement in ECG

peaked P wave (p pulmonale)

43

left atrial enlargement in ECG

notched P wave ( P mitrale)

44

standard for diagnosis and categorization of partial or complete AVSD

2d echo

45

what should you do if you want to determine hemodynamic values in AVSD

cardiac catheterization

46

Usually done on patients with Down syndrome with
inherent pulmonary hypertension, to determine the
operativity of the defect

CARDIAC CATHETERIZATION AND ANGIOGRAPHY

47

symptoms of artial avsds are more severe due to

MR in infancy

48

objectives of surgical repair in partial avsd

closure of interatrial communication
Restoration & preservation of the left
atrioventricular valve

49

in complete avsd there is presence of

complete heart block:
atrioventricular dissociation

50

symptoms in complete avsd is a result of

-Large increase in pulmonary blood flow
-Increased pulmonary artery pressure
-Insufficiency of the common atrioventricular valve

51

in terms of axis deviation in ECG, compare partial to complete avsd

complete avsd has more superior axis deviation

52

gooseneck deformity is seen in

complete avsd

53

gooseneck deformity is due to

anterior displacement of LVOT in avsd and produces elongation of LVOT
