  1. Aortic Stenosis:
    • Aortic VALVE LEAFLETS become STIFF, FUSED, or CALCIFIED.
    • IMPEDE FLOW from LV into the AORTA during VENTRICULAR SYSTOLE
  2. Aortic Stenosis: Caused By
    • congenital malformation
    • inflammatory heart disease (ENDOCARDITIS)
    • Calcification
  3. Aortic Stenosis: Pathyphysiology
    • AORTIC VALVE NARROWS
    • obstructs flow into aorta during SYSTOLE
    • INCREASED LV pressure
    • LV HYPERTROPHY
    • cardiac output fixed
  4. Aortic Stenosis: Causes
    <30 congenital stenosis

    30-65 progressive stenosis

    >65 degeneration/sclerosis of valve
  5. Aortic Stenosis: Diet
    • UNRESTRICTED
    • unless heart failure is present
  6. Aortic Stenosis: Diagnostic testing
    • ECG
    • :late stages will reveal left ventricular hypertrophy, nonspecific ST depression,
    • T wave inversion that indicates subendocardial ischemia

    Chest x-ray:aortic calcification
  7. Aortic Stenosis: Assessment
    • Early symptoms: fatigue and dyspnea
    • dyspnea,
    • exertional angina ,
    • syncope or near-syncopal episodes
    • indicates severe aortic stenosis
    • Individuals who develop symptomatic heart failure survive less than 2 years
    • The hallmark clinical findings:A grade III/VI or IV/VI systolic ejection murmur
    • over the aortic area radiating upward into the carotid arteries and a pulse pattern
    • that demonstrates a delayed systolic upstroke
  8. Aortic Stenosis: MURMUR
    SYSTOLIC MURMUR BETWEEN S1-S2

    crescendo-decrescendo

    • S2 CLOSES WEAK, SOFT SOUNDING
    • Right Upper sternal border radiates to carotids

    • Carotid pulses are weak and delayed:
    • SYNCOPE, DIZZINESS
