valve damage, perforation of heart, CNS injury, stroke, death

interventional cardiac catheterization procedures in children

ballon atrial septostomy, balloon dilation, stent placement, coil occulsion, transcatheter device closure, transcatheter valve replacement, radiofrequency ablation

CHD is strongly associated with...

chromosomal abnormalities and specific syndromes

CHD occurrence ratio

1 in 110 live births

Common s/s of CHD

poor feeding, tachypnea, tachycardia, diaphoresis, crackles, hepatomegaly, cyanosis, murmur, sternal lift

acyanotic defects

- increase in pulmonary blood flow
- obstruction of blood flow from ventricles

cyanotic defects

-decreased pulmonary blood flow
-mixed blood flow

Increased Pulmonary Blood Flow Defects

-abnormal connection between two sides of heart
-increased blood volume on right side of heart
-increased pulmonary blood flow
-decreased systemic blood flow

Types of Increased Pulmonary Blood Flow Defects

Atrial septal defect (ASD); Ventricular septal defect (VSD); Patent ductus arteriosus (PDA)

left-sided obstructive congenital heart defects

-Structural abnormality on the left side of the heart
-Decreased systemic blood flow
-decreased pulses, unequal limb blood pressures, mild to extremely ill presentation
-Ex: Coarctation of the aorta, aortic stenosis

right-sided obstructive congenital heart defects

-Narrowing at entrance to the pulmonary artery
-RVH and decreased pulmonary blood flow
-cyanosis (mild), murmur, HF
-Ex: Pulmonic stenosis

Decreased Pulmonary Blood Flow Defects

-structural abnormality causing too little pulmonary blood flow
-Abnormality on the right side of the heart
-causes unsaturated blood to shunt to the left side of the heart, into the systemic circulation
-usually hypoxemic and cyanotic

types of decreased pulmonary blood flow defects

Tetralogy of Fallot;
Tricuspid atresia; pulmonary atresia

Tetralogy of Fallot

congenital malformation involving four distinct heart defects; "RAPS"
-Right ventricular hypertrophy
-Aortic disposition (it is connected to both ventricles)
-Pulmonary stenosis,
-Septal defect (ventricular)

types of mixing congenital heart defects

-transposition of great vessels/arteries (TGA)
-total anomalous pulmonary venous connection/return (TAPVR)
-hypoplastic left heart syndrome (HLHS)

transposition of the great vessels (TGA)

-great vessels (arteries), aorta, and pulmonary artery arise from the wrong ventricle
-aorta comes off of RV
-pulmonary artery comes off of LV
-must have ASD, VSD, or PDA to allow "mixing" of blood

total anomalous pulmonary venous return (TAPVR)

-all four pulmonary veins drain abnormally to the right atrium by way of an abnormal (anomalous) connection
-classified based on how and where the pulmonary veins drain to the heart (supracardiac, cardiac, infracardiac)

Hypoplastic Left Heart Syndrome

underdevelopment of the left side of the heart, usually resulting in an absent or nonfunctional left ventricle and hypoplasia of the ascending aorta; one of the most complex and most challenging to manage; treat with palliation and/or heart transplant

-Corrective lenses, surgery
-Astigmatism
-Generally detected with vision screening at PCP or school
-(Refraction is the bending of light rays as they pass through the lens of the eye. With normal refraction, light passes through the lens and fall directly on the retina. With refractive errors the light rays fall in front of or behind the retina)

strabismus

-Type of visual impairment
-One eye deviates from the point of fixation
-Eyes are misaligned
-More commonly known as cross eyes
-Binocularity usually occurs by 3 to 4 months of age

strabismic amblyopia

-If not detected and corrected by 4-6 years of age, strabismus can lead to strabismic amblyopia
Develops over time from the eyes not being aligned
-Brain "turns off" the eye that is not aligned and eventually vision is lost in that eye
