Narrowing of aortic valve, which obstructs blood flow from left ventricle to aorta this
worsens, the heart can’t overcome worsening obstruction, and ejects a smaller fraction
of blood volume each systole
Decreased ejection fraction, narrowed pulse pressure
Blood being pumped out insufficient to meet metabolic demands
Patients will have exertional dyspnea, chest pain, and syncope
Tear in the inner lining of the aorta that allows blood to surge between layers of arterial
wall
Before surgical repair, the priority is maintaining pressure in the aorta
Administer IV beta blocker
Always assess BNP in these patients
Elevated BNP indicates increased ventricular stretch and correlates with severity of heart
failure and fluid volume overload. (increased HR, Hypertension, edema, crackles)
Elevated BNP is an expected finding in HF patients
These patients will have DECREASED urine output
Patient teaching: Daily weight, sodium restriction, take own pulse if taking digoxin or
beta blockers, take BP and keep record of it, increase activity gradually, plan rest periods,
consider cardiac rehab program, avoid extreme hot/cold
Report these symptoms: weight gain of 3 lb in 2 days, or 3-5lbs in a week, difficulty
breathing when lying flat/exertion, waking up breathless at night, dry, hacky cough,
fatigue, dizziness, swelling of feet, ankles, abdomen, face
To assess for presence of this, nurse would listen with bell of stethoscope in epigastric
area slightly left of midline
Renal perfusion status monitored closely
Monitor for hypotension, dehydration, blood loss, embolism
Check BUN and creatinine, and urine output (at least 30mL/hr)
Manifestations of graft leakage: ecchymosis of the groin, penis, scrotum, or perineum,
increased abdominal girth, tachycardia, weak pulses, decreasing hct and hgb, pain in
pelvis, back, or groin, and decreased urinary output
