265
foramen ovale
bypass the lungs
266
ductus venosus
bypass the liver

what are the two principal clinical consequences that can occur from congenital heart defects?
- CHF - caused by defects that result in left to right shunting of blood
- hypoxemia - caused by defects that result in decreased pulmonary blood flow
272
clinical consequences that occur with increased pulmonary blood flow
- the systemic pressure is greater than the pulmonary pressure, so left to right shunting occurs*
- increased blood volume on the right side of the heart increases pulmonary blood flow at the expense of systemic blood flow
- clinically - s/s of CHF (defects that result in left to right shunting of blood cause symptoms of HF)
273
CHF
the inability of heart to pump enough to meet the heart's demands
274
CHF can be caused by
- FVE
- pressure overload
- decreased contractility
- high cardiac output demands
275
in children, CHF occurs more frequently with
congenital heart defects in which structural abnormalities result in a volume load or pressure load on the ventricles
276
CM of CHF
- pulmonary venous congestion - tachypnea, wheezing, crackles, retractions, cough, dyspnea on exertion, grunting, nasal flaring, cyanosis, feeding difficulties, irritability, fatigue with play
- systemic venous congestion - hepatomegaly, ascites, edema, weight gain, NVD
- impaired myocardial function - tachycardia, weak peripheral pulses, hypotension, gallop, cooler extremities, oliguria, fatigue, restlessness, enlarged heart, sweating
- high metabolic rate - FTT, slow weight gain, perspiration
277
therapeutic management of CHF

- treatment - mild defects may close spontaneously, open heart surgery and dacron patch closure, may be closed using devices during heart cath
284
ventricular septal defect

- CM - CHF, moderate to severe, cyanosis, characteristic murmur, right ventricular hypertrophy, FTT< fatigue, recurrent respiratory infections
- treatment - pulmonary artery banding, may close spontaneously by age 3, interventional heart cath with septal occluder or surgical correction with a patch and repair of AV valve tissue
285
patent ductus arteriosus
the fetal structure fails to close, blood is shunted from the aorta to the pulmonary artery
- CM - machine-like murmur, can be asymptomatic, or CHF
- treatment - indomethacin, interventional heart cath with coil, left thoracotomy or VATS
286
clinical consequences of obstructive lesions

- obstruction usually occurs near the valve as in aortic and pulmonic stenosis
- either shunting or back up of blood on the right side
- increased pulmonary congestion
- signs of CHF
287
coarctation of the aorta
narrowing of the aortic arch, usually distal to the ductus arteriosus and beyond the right subclavian artery that results in increased pressure proximal to the defect and decreased pressure distal to the defect

- management - prostaglandin E to maintain PDA, balloon angioplasty, surgery within first 2 years
288
aortic stenosis
- narrowing or fusion of aortic valves with interferes with left ventricular outflow. blood backs up into right side of heart and right side of heart enlarges
- results in decreased cardiac output, left ventricular hypertrophy, pulmonary vascular congestion
- serious defect** - obstruction tends to be progressive, sudden episodes of myocardial ischemia, low cardiac output, can result in sudden death, only defect where activity is limited, surgical repair rarely results in normal valve
- CM - infants have faint pulses, hypotension, tachycardia, poor feeding, children have exercise intolerance, chest pain, and dizziness when standing for long periods
- treatment - ballon dilation or surgery (aortic valvotomy or replacement, mortality is high for older kids)
- activity level is restriced in children with aortic stenosis even though the chance of sudden death is very rate
- children are not on bedrest, but activity level is restricted
- curtail strenuous activities
289
pulmonic stenosis
- defect that involves narrowing or constriction of valves of the pulmonary artery interfering with right outflow

- CM - may be asymptomatic, some have mild cyanosis or CHF, murmur
- treatment - balloon angioplasty, surgery
290
pulmonary atresia
extreme form, total fusion resulting in no blood flow to lungs
291
cyanotic defects def
- caused by defects that result in deceased pulmonary blood flow
- in cyanotic the pressure is greater on the pulmonic side so blood shunts from the right to left
- mixed oxygenated and deoxygenated blood flows to the systemic circulation resulting in hypoxia
292
cyanotic defects symptoms
cyanosis, polycythemia, digital clubbing, altered ABG
293
general interventions for cyanotic heart defects
- provide good skin care
- supplemental O2
- monitor for and prevent dehydration
- developmentally appropriate prep for procedures
294
NC for cyanotic defects
- alteration is oxygenation
- anxiety caused by cyanosis
- dehydration
- prevention and accurate assessment of respiratory infections
295
tetralogy of fallot
combination of 4 defects (pulmonic stenosis, right ventricular hypertrophy, overriding aorta, ventricular septal defect)
CM - heart murmur with a thrill, polycythemia, hypoxic episodes, metabolic acidosis, poor growth, clubbing, exercise intolerance
- improved quality of life and longevity with surgery, done in stages
296
squatting position in tetralogy of fallot
reroutes blood
increases vascular resistance
decreases blood return from legs
divert more blood to pulmonary artery
297
guidelines for hypercapnia spells
- employ calm comforting speech
- knee chest position
- 100 oxygen by face mask
- give morphine
- Iv fluid replacement and volume expansion if needed
- repeat morphine as needed
298
tricuspid atresia
- failure of the tricuspid valve to develop resulting in no communication between right atrium and ventricle resulting in severe right hypoplasia or absence of the right ventricle
- CM - cyanosis
- treatment - prostaglandin E to maintain foreman ovale, digi and diuretics, palliative surgical repair to increase pulmonary blood flow
299
transposition of great arteries
- pulmonary artery arises from left ventricle and the aorta arises from the right ventricle. no communication between the systemic and pulmonary circulations
- s/s - increasing cyanosis as foramen ovale closes
- treatment - arterial switch procedure in the first few weeks of life, IV prostaglandin E to keep foramen ovale open and or balloon atrial septostomy
300
truncus arteriosus
pulmonary artery and aorta fail to divide during embryotic development, one single large vessel empties both ventricles
- CM - cyanosis, CHF, heart murmur
- treatment - surgical repair during the first few months of life
- digoxin and diuretics
301
hypoplastic left heart syndrome
aortic valve atresia, mitral atresia or stenosis, small or absent left ventricle, severe hypoplasia of the ascending aorta and aortic arch
- underdevelopment of left side of the heart
- descending aorta receives blood via the PDA
- S/S - cyanosis, weak peripheral pulses, cool extremities, respiratory distress, often times no murmur
- management - prostaglandin E to keep PDA, fontan procedure, norwood procedure, transplant*
302
fontan procedure
direct blood flow to pulmonary artery from RA
303
norwood procedure
anastomosis of main PA to aorta, shunt from RV to PA
304
complications of heart surgery
- CHF
- dysrhythmias
- cardiac tamponade
- atelectasis, pneumothorax, pulmonary edema, PE
- cerebral edema and brain damage
- hemorrhage or anemia
