25
FEV1/FVC normal
0.8
26
obstructive (FEV1/FVC)
<0.7, FEV1 decreased
27
restrictive (FEV1/FVC)
normal or increased, FEV1 decreased
28
normal aortic valve size
2.5-3.5cm2
29
aortic stenosis A. Line waveform
- pulsus tardus | - pulsus parvus
30
aortic stenosis time to death 1. angina pectoris 2. syncope 3. dyspnea on exertion
1. 5 years 2. 3 years 3. 2 years
31
aortic stenosis decrease murmur intensity
valsalva and sustained handgrip
32
aortic stenosis peri-op goals (4)
1. maintain NSR 2. avoid tachy or brady 3. avoid hypotension 4. optimize intravascular fluid volume
33
aortic stenosis CPR
- not effective | - can't create adequate stoke volume against stenotic valve
34
mitral stenosis
increases LA pressure and volume, pulmonary HTN, stress induced pulmonary edema, right CHF
35
at risk for mitral stenosis
- females | - rheumatic heart disease
36
normal mitral valve
4-6
37
mitral stenosis EKG
broad notched P wave (A. Fib 1/3)
38
mitral stenosis peri-op goals
- maintain CO (avoid increased HR) - maintain NSR - maintain euvolemia - avoid hypercarbia, hypoxemia - epidural>spinal for HR/BP control
39
aortic regurg
- eccentric and concentric LV gypertophy - decreased coronary blood flow - LVF and pulmonary edema
40
risk factors aortic regurg
- Acute (endocarditis, aortic dissection, trauma) | - Chronic (rheumatic fever, bicuspid aortic valve, idiopathic aortic root dilation)
41
severe aortic regurg
>50%
42
severity of regurg is a function of...
- time (HR) | - pressure gradient (SVR)
43
AR meds
- PO (nifedipine, hydralazine) | - IV (nitroprusside, dobutamine)
44
AR assessment
- dyspnea, fatigue, angina - widening pulse pressure - bounding peripheral pulses
45
AR peri-op goals
FAST-FULL-FORWARD - HR >80, consider IVF bolus and afterload reduction - avoid decreased HR and sudden increase SVR - GA>neuraxial
46
AR induction
consider panc
47
mitral regurg
-decreased SV and CO -LA becomes volume overloaded (pulmonary congestion, LV hypertrophy, impaired contractility) (chronic or acute)
48
risks for MR
MVP, ischemic HD, LVH, previous rheumatic fever, congenital HD, lupus, rheumatoid arthritis
49
severe MR
>50%
50
MR PA waveform
large V wave
51
MR surgery
EF >60 beneficial | EF <30 futile
52
MR anesthesia
1. kep HR 80-100 (decrease ventricular filling time) 2. slightly decrease SVR (maximize forward flow, reduce afterload, avoid further drop CO) 3. caution with myocardial depressant drugs (my have ventricular impairment)
53
MVP
(common, often benign) 1. systole (one or both leaflets prolapse back into LA, with or w/o regurg) 2. primary MVP (leaflets thickened d/t connective tissue dz) 3. functional MVP (leaflets have mid bowing- normal variant)
54
risk factor MVP
- female - marfan's - previous rheumatic fever - thyrotoxicosis - lupus
55
diagnosis MVP
ECHO: valve prolapse of 2mm or more above the mitral annulus most patients asymptomatic
56
MVP anesthesia
want to increase LV filling and decrease LV emptying (a larger ventricle will have less prolapse) 1. avoid prolonged SVR 2. minimize SNS stimulation (avoid arrythmias) avoid ketamine, no beta-agonists (ephedrine)
