Definition of a shunt:
Blood flow through an opening between two structures or vessels of the heart
Definition of Murmur:
A sound heard when listening to the heart; reflects flow of blood within the heart
-Normal during periods of rapid growth
What is CHF?
Inability of the heart to perform its function of pumping blood forward

-B-type natriuretic peptide
-Chest x-ray
-Exercise test
-Echocardiogram: looks at direction of blood flow
-MRI
-Cardiac cath
Nursing care for CHF:
-Comfort care
-Oxygenation
-Skin care
-Continious V/S monitoring
Medications for CHF management:

Foods high in potassium (banana, broccoli, grapefruit)
What is cardiac catheterization used for?
Diagnosis and repair for CHF
Nursing management for Cardiac Cath:
-Pressure dressing
-Monitor V/S
-Check for pulse distally
-Immobilization of patient
-Bedrest for 6 hours afterwards
-Quiet play for 24 hours
What medications do we give for any congenital heart defect?
-Angiotensin Converting Enzymes (ACE) inhibitor (Captopril)
-Cardiac glycoside (Digoxin)
-Loop Diuretic (Furosemide)
Does pulmonary blood flow increase or decrease with acyanotic CHD?
Increase
Does pulmonary blood flow increase or decrease with cyanotic CHD?
Decrease
ANY CHD that starts with a T or H is considered an _______ defect
Cyanotic defect. If it doesn’t start with T or H, is is acyanotic.
5 Ts and H (hypoplastic Left sided heart defect)
What is the Increased pulmonary blood flow defect? What are the types?
An abnormal connection between two sides of the heart.
-Atrial Septal Defect
-Ventricular Septal Defect
-Patent Ductus Arteriosus
How is blood flow affected in the Increased pulmonary blood flow defects?
-Increased pulmonary blood flow
-Decreased systemic blood flow
What is an Atrial Septal Defect?
Simple defect of the atria
Clinical manifestations for Atrial Septal Defect:
-Possible Murmur or Thrill
-Possible right atrium enlargement
-Hepatomeagly (fluid overload)
-SOB
-Respiratory distress
-Periorbital edema

What is a Ventricular Septal Defect?
Defect in the ventricular septum.
