Pediatric Cardiac Flashcards
How is congenital heart disease classified?
- Structural Abnormalities
- Functional Alterations
- Both of these
Caused by failure of the fetal______ ______ to completely close after birth. What classification is this?
- Ductus Arteriosis
* Left to Right shunting lesions
What stimulates Ductus Arteriosis to close? When does this usually occur?
- Increased O2 in blood when infant begins to breathe
* 10-15 hours after birth
Manifestations of PDA?
- May be asymptomatic
- Continuous murmur (Machine like)
- Widened pulse pressure/bounding pulses (diastolic pressure is lower because blood is leaking from aorta)
- Enlarged heart on CXR (heart is working harder)
- Tachypnea
- Poor feeding, Poor Weight gain
When Ibuprofen is given for PDA, What is the intended end result?
Facilitates necrosis of intima of ductus arteriosis, resulting in halting of ductal flow.
An NSAID/______Inhibitor called ____that causes PDA to ____resulting in a ______ vessel.
- Prostaglandin
- INDOMETHACIN (INDOCIN)
- Constrict
- Closed
When a Cardiac cath is done for PDA, a ____ is placed. ______ will be given prophylacticly for _____ to prevent ________.
- Coil
- Antibiotics
- 6 months
- Infective endocarditis
When is indomethacin used for treatment of PDA?
when other medical treatments fail after 48 hours.
an opening between the atria, allows blood flow from the right to the left atrium
Foraman ovale
blood flow between the pulmonary artery and the aorta, shunting blood away from the pulmonary
circulation
Ductus arteriosis
Most ASD cases present as ________. In these cases you want to monitor for what?
- Asymptomatic
* monitor for closure
How are ASD symptomatic children and infants treated?
- Diuretics for fluid back up
- Digoxin for HF
- antiarrythmics
Surgical procedures for ASD?
Cardiac cath - transeptal closure
Amplatzer Septal Occluder device
Manifistations for ASD?
- Pulmonic murmur
- DOE/fatigue
- Atrial dysrythmias
- Recurrent Respiratory infections
Large ventricular septal defects can cause?
Pulmonary hypertension
with VSD where can you hear the murmur? What does it sound like?
- LSB at the 3rd or 4th intercostal space
* Loud and harsh with palpable thrill
Some manifistations/complications of VSD? How are these managed?
- CHF -Digoxin,Diuretics, ACE to decrease afteroad
* Poor feeding/failure to thrive- NG tube/gastrostomy
20-80% of all VSDs do what? If they dont, what can be done?
- Close spontaneously
* Cardiac cath/repair
Endocardial cushion defect is another term used to describe this defect. What is this associated with?
Atrioventricular Septal Defect (AVSD)
Genetic defects like downsyndrome
in AVSD when does CHF develop?
when pulmonary pressures are low and there is a large amount of L to R shunting
