1

What is an atrial septal defect?

defect w/ increased pulmonary blood flow (atrial)

2

What is a ventricular septal defect?

defect w/ increased pulmonary blood flow (ventricular)

3

What are the manifestations for atrial septal defect?

asymptomatic

HF (possible)

loud harsh murmur

4

What is the pathophysiology of an atrial septal defect?

hole in the septum between the right and left atria that results in increased pulmonary blood flow (left-to-right shunt)

5

What are the manifestations of a ventricular septal defect?

loud harsh murmur (heard at left sternal border)

HF

can close spontaneously

6

What is the pathophysiology of ventricular septal defect?

hole in the septum between right and left ventricle that results in increased pulmonary blood flow (left-to-right shunt)

7

What is patent ductus arteriosus?

defect with increased pulmonary blood flow

ductus arteriosus does not close

8

What are the manifestations of patent ductus arteriosus?

murmur (machine hum)

wide pulse pressure

bounding pulses

asymptomatic

HF
wet breath sounds

9

What is the pathophysiology for patent ductus arteriosus?

ductus arteriosus doesn't close in fetus causing increased pulmonary blood flow

10

What is coarctation of the aorta?

obstructive defect

11

What are the clinical manifestations of coarctation of the aorta?

elevated BP in upper extremities & decreased BP in lower extremities

12

What is the pathophysiology of coarctation of the aorta?

narrowing of the lumen of the aorta usually at or near the ductus arteriosus that results in obstruction of blood flow from the ventricle

13

What is the tetraology of fallot?

decreased pulmonary blood flow

14

What are the manifestations of tetraology of fallot?

cyanosis at birth

systolic murmur

episodes of acute cyanosis and hypoxia (tet spells)

15

What is CHF?

right or left sided heart failure

16

What are the manifestations of CHF?

tachycardia

tachypnea

fatigue

irritability

sudden weight gain and edema

heptospleenomegaly

lung congestion

ascites

17

What is the pathophysiology of CHF?

inability of heart to pump an adequate amount of blood into systemic circulation

18

What is Kawasaki disease?

monocutaneous lymph node syndrome

5 days of high fever

19

What are the manifestations of Kawasaki disease?

red lips

strawberry tongue

sore joints

rash

conjunctiva is red

large lymph nodes

high WBC

20

What is the pathophysiology of Kawasaki disease?

acute systemic vasculitis of unknown cause

increased risk of forming coronary artery aneurysm

high dose aspirin

IgG
