Acyanotic Heart Defects

Question 1

2 Kinds of Congenital Heart Disease

Answer 1

Acyanotic: L-R shunt or no shunting
Cyanotic: R-L shunt

Question 2

Most Common ASD

Answer 2

Secundum ASD

Question 3

ASD (symptomaticity, path effects, physical exam finding, intervention)

Answer 3

Usually asymptomatic
R heart V overload with enlargement and increased pulmonary blood flow
Wide fixed split b/w A and P
Usually don’t need intervention, maybe surgery or cath

Question 4

2 Types VSD

Answer 4

Membranous and Muscular. Membranous more common in adulthood

Question 5

VSD (path effects, physical exam finding, intervention)

Answer 5

L->R shunt at ventricular level, but only systolic so moves right on through to lungs back to L side so get L heart V overload
Commonest pansystolic murmur in peds
Small defects will close over time, large need surgery

Question 6

PDA (path, 2 physical exam findings, danger)

Answer 6

LH V overload
Wide pulse pressure and continuous murmur by P valve
Can cause CHF so needs repair/closure on dx

Question 7

AV Septal (Canal) Defect

Answer 7

Common outflow, increases PBF so LH V overload again. Presents at 1-2 months w/ CHF (not feeding) and common in DS

Question 8

Eisenmenger’s Syndrome

Answer 8

Prolonged LR shunt leads to irreversible pulm HTN, pretty much dude gon die from it
