23
Q

MS

24
Survival of MS
No symptoms 10 year survival 80-100% Limiting symptoms 10 year 0-15% Pulm HTN < 3 years
25
MR severe
``` Jet area >0.5 Regurgitant volume >60 Regurgitant fraction >55% Vena contracts >0.7 cm ERO >0.4 Normal LA the MR is not severe ```
26
MR types
Type 1 dilated root Type 2 prolapse Type 3 pap dysfunction 3b ischemic
27
Increase MR
DecreAse survival Increase CV events LV gram is still gold standard
28
Moderate MR
Annual echo
29
Indication for mitral surgery
EF >30% ESD 55 if chordal preservation likely, medical therapy if chordate can't be preserved Severe MR EF < 60% or ESD >40 mm New onset afib or pulm HTN Do early before symptoms worsen
30
MR
Repair if possible
31
Pulm stenosis
``` Isolated Tetralogy Rubella Carcinoid Gradient >4m/sec Treatment valvuloplasty ```
32
Pulm regurgitation
``` Carcinoid Tetralogy Endocarditis RV overload Bio prosthetic ```
33
TRicuspid stenosis
``` Rheumatic Carcinoid Congenital Fabry Drugs ergot Valve area 1 cm2 balloon or bio prosthetic ```
34
TR
``` Pulm HTN Cardiomyopathy Left sided valve disease Rheumatic Ebstein Radiation ```
35
Surgery severe TR
Severe TR in peopke undergoing left sided valve surgery Less than severe TR with left sided valve surgery if there is pulm HTN Severe TR with symptoms Primary TR with RV failure
36
MS and AI
Pressure half time of MS will be long and pressure half time of AI will be short
37
Carcinoid
``` Primary GI Cardiac involvement 50% Check 24 hour urine 5-HIAA Octreo scan Ergot Diet drugs ```
38
Radiation effects
10-15 years after radiation Coronaries valves and pericardium Concomitant chemo MR and AI
39
Antiphospholipid antibody
Superficial thrombosis Non bacterial endo Regurgitation MR AI
40
Endocarditis
Blood cultures single for coxiella Evidence if vegetation Echo evidence
41
Endocarditis
DX 2major 1 major 3 minor 5 minor
42
Prophylaxis
``` Prosthetic valves Prior endo Unrepaired cyanotic congenital Repaired with residual Transplant with Regurgitant lesions ```
43
Bio prosthetic after 70
``` Routine yearly echo class 2b Regurgitation detected every 3/6 mos ```
44
Mechanical valves and Coumadin
Stroke untreated 4-8% a year Treated 1-2% year Bio prosthesis 1-2% a year
45
Anticoag guide lines
Afib Previous CVA Hypercoagulable state EF <30%
46
Asa 75 all mechanical and bio
INR 2-3 mechanical AVR and 3 MIs for bio INR 2.5-3.5 for the rest
47
Short term interruption of Coumadin
``` Bi leaflet AVR no bridge Bridge all the rest with UFH Lmwh is ok now FFP urgent cases No vit K ```
48
Bio prosthetic
20-30% dysfunction in 10 yrs 50% by 15 years Increase in young pregnancy and RF Look for patient valve mismatch
49
Valve thrombosis | 2% per year
``` Thrombolysis effective 70-90% More on the right sided Mortality 4-12 % with lysis Surgery for large clot class 3-4 Small clot class 1-2 consider lysis ```
50
Endocarditis
Mitral more common 0.5% even with antibiotics Stable endo no surgery needed Hemolysis may need to be replaced
51
AS surgery
Symptomatic EF less than 50% no symptoms Worsening gradient Abnormal stress test
52
MS
Symptomatic survivsl 50% | Valvuloplasties symptomatic or asymptomatic with moderate to severe disease with pulm HTN
