What are the 2 types of atrial septal defects?
|
ASD- Osteum primum
ASD- Osteum secundum |
|
What signs and symptoms are associated with ASDs?
|
Pulmonary congestion, right heart hypertrophy, eventual heart failure.
|
|
A baby is born with a severe hypoplasia (under-development) of the left heart and dies shortly after birth. What defect was the baby born with, and why did it die?
|
Premature closure of the foramen ovale.
Death occurs because the left heart can't handle the blood volume after birth. |
|
What abnormality is characterized by failure of the endocardial cushions to fuse?
|
Pesistent AV canal with ASD and VSD.
|
|
A baby presents with a hypoplastic right ventricle, a hypertrophic left venttricle, and cyanosis. What does the baby have, and what septal defects are present?
|
Tricuspid atresia with patent foramen ovale (ASD osteum secundum) and VSD.
|
|
What is the most common type of heart defect? What developmental failure causes this defect?
|
A membranous septum VSD; failure of the endocardial cushions to fuse with the muscular IV septum.
|
|
What four anatomical defects are associated with Tetralogy of Fallot?
|
S: Stenosis of the pulmonary artery
H: hypertrophy of the right ventricle O: Overriding aorta V: VSD |
|
Persistent truncus arteriosus is a result of what developmental failure?
|
The failure of the bulbar ridges of the spiral septum to fuse together.
|
|
Transposition of the great vessels is caused by what? Why does this failure cause a problem? Under what circumstance is it fatal?
|
Failure of the spiral septum to spiral. The end result is two closed circuits. It is fatal when there is no anatomical connection between the circuits.
|
|
Which three heart anomalies result in cyanosis?
|
3 Ts:
Tetralogy of Fallot, Tricuspid atresia, Transposition of the great vessels. |
