Define MVP.
|
Displacement of any portion of the MV leaflets beyond the MV annular plane during systole
|
|
Causes of MVP
|
Flail MV leaflets
Marfans Syndrome Flail Chordae or pap muscle dysfunction Infective endocarditis Myxomato changes (thickening/fibrin deposits) Mitral annular dilation Familial/Non-familial connective tissue disease |
|
Symptoms of MVP:
|
Most are asymptomatic
Palpitations (most common) Chest pain (atypical, non-exertional) Dyspnea, fatigue, exercise intolerance Anxiety / Panic attacks Murmur – mid-systolic click or med to high pitched late systolic murmur if MR present |
|
Complications of MVP:
CHF if there is severe MR – leading to pulmonary hypertension Increased risk of endocarditis Increased risk for embolic events |
CHF if there is severe MR – leading to pulmonary hypertension
Increased risk of endocarditis Increased risk for embolic events |
|
In what time (s) of the cardiac cycle can MVP occur?
|
Mid-systolic or holo-systolic
|
|
Best views for assessing MVP.
M-Mode: |
posterior decent of lines of closure of MV in systole
Can see in mid-systole or holosystole LAE if MR |
|
Best views for assessing MVP
2D: |
Use PLA and A4C
Find annulus and draw a mental line across the annulus. If >2mm past line then MVP Thickened valvular or sub-valvular apparatus (redundant) |
|
Best views for assessing MVP
Color Flow |
Color Flow can reveal location and extent of MR. MR jet usually eccentric
|
|
Doppler
|
Doppler to assess degree of MR using CW/PW
|
|
Other Characteristics
|
Can involve one or both leaflets
MR may or may not result from MvP TV prolapsed occurs up to 50% |
