E2: Pediatric Cardiac Conditions

What is a L→ R shunt?

hole or opening in the heart that is flowing from the left side of the heart to the right side of the heart

what does a L→ R shunt cause in the body?

increase blood flow to the lungs and pulmonary system

over circulation causing fatigue, SOB, pulmonary HTN

What is a Acyanotic Defect?

typically associated w/ L → R shunt

no cyanosis, but heart can become over loaded

what is a R→ L shunt?

hole or opening in the heart causing blood to flow from the right side of the heart to the left side of the heart

what does a R→ L shunt cause in the body?

increased deoxygenated blood circulating systematically

tissue hypoxia

O2 stat decrease

what is a Cyanotic Defect?

R → L Shunt

cyanosis present

exercise restrictions and fatigue

what does hypoxemia mean?

low O2 in blood

what does Hypoxia mean?

low O2 in the tissue

What is a Atrial Septal Defect? (ASD)

hole in the septum between the right and left atria

Cyanotic or Acyanotic, Shunt Type? Atrial Septal Defect

Acyanotic

L → R

what impact does an Atrial septal defect have on exercise?

if its small, tolerate it well

if its large, fatigue, sob, decreased endurance

Describe a Aortic Stenosis

narrowing of the aortic valve

Cyanotic or Acyanotic, Shunt Type? Aortic Stenosis

Acyanotic

NONE- obstructive, small valve

what impact on exercise does a Aortic Stenosis have?

exercise tolerance decrease depending on stenosis severity

Describe a coarctation of the aorta

restricts blood flow to lower half of body

past main branches off aortic arch

Cyanotic or Acyanotic, Shunt Type? Coarctation of aorta

Acyanotic

non, obstruction to vessel

What impact on exercise does a coarctation of the aorta have?

decrease exercise tolerance

decreased o2 delivery to tissue

describe a Ebsteins anomaly

malformed tricuspid valve causing valve regurgitation and right atrial dilatation

Cyanotic or Acyanotic, Shunt Type? Ebstiens anomaly

Acyanotic

non, valve malformation

How does a ebsteins anomaly
