Two Major Groups of Cardiac Disorders:
- Congenital ("born with;" most structural defects)
- Acquired (developed later in life)
What are the two older classifications of congenital heart disease (CHD)?
- Acrocyanotic: Pink; NO unoxygenated blood is going to periphery
- Cyanotic: Blue (may be pink); unoxygenated blood is shunted to the periphery
What are the 4 major classifications of CHD?
1. Increased pulmonary blood flow
2. Reduced pulmonary blood flow
3. Obstruction of forward flow out of the heart
4. Mixed blood flow
Which of the above categorizations are included under ACROCYANOTIC
Increased pulmonary blood flow & forward flow obstruction from ventricles
Which of the above categorizations are included under CYANOTIC
Reduced pulmonary blood flow & mixed flow
Increased vs decreased pulmonary blood flow
Increased: excessive amount to lungs (pink color); pulmonary congestion
Decreased: insufficient amount to lungs (blue color); cyanotic
If the blood flow becomes obstructed in the ventricles, what happens?
blood flow cannot reach lungs or body
____________________ is the most common CHD classification.
, mixed blood flow
What are hemodynamics?
physical principles of blood flow based on pressure and resistance
The greater the pressure gradient, the _______ _____ ______ ___ ________.
greater the rate of flow
The greater the resistance, the ____________________.
the lower the rate of blood flow
Pressure & resistance in a NORMAL heart:
In the NORMAL HEART, pressures on the R side are less than the L side, and the
resistance in the pulmonary circulation is less than that in the systemic circulation
For CCHD screening, which hand do we place the pulse oximeter and why?
Right hand (pre-ductal) and either foot (post-ductal) -- DONE AFTER BABY ALIVE FOR
AT LEAST 24 HOURS
What does pre-ductal mean?
Pre-ductal saturation measures the amount of arterial oxygen within the blood after
blood leaves the heart but BEFORE it reaches the ductus arteriosus of the aorta where it
gets delivered to the upper extremities such as the brain etc.
What is cardiac catheterization?
It is an invasive, diagnostic procedure done to image the interior of the heart along with
its pressures, O2 sats, and hemodynamic values
What are the major risks of cardiac catheterization?
hemorrhage, low-grade fever, N/V, loss of pulse, transient dysrhythmias
Pre-procedure considerations for cardiac catheterization:
- Complete Hx & physical exam
- Provide age appropriate teaching
- Mark pedal pulses
- NPO 4-6h prior to
- Monitor vitals/labs
What allergies you want to monitor for with a cardiac cath?
