MV replacement, Percutaneous balloon valvotomy (not possible with severe calcification, MS score <8 best candidate)
Mitral Stenosis causes leaflets to open with ________ motion. Anterior leaflet appears as _______ _______ in _________(cardiac cycle).
doming motion, hockey stick, diastole.
What are the factors affecting pressure gradients?
Volume status, heart rate and stroke volume.
True/ False: Parachute MV is when all chordae attach to a single papillary muscle.
True.
True/ False: Decreased excursion in M-mode is Hallmark of MS.
False. Increased echogenecity of the leaflets is Hallmark of MS.
What am I? A reflection of the rate at which Left atrial and ventricular pressures equilibrate during diastole.
PHT. (220/PHT=MVA) (PHT 220 or greater will give severe MS) (with RCM or IHD PHT may falsely increase due to elevated LVEDP)
True/ False: Mitral valve was the first 4 of the cardiac valves to be evaluated with echo.
True. facts
What is the classic form of MV disease?
Rheumatic Heart disease which involves leaflets and chordae.
Peak Gradient is calc by the bernoulli equation. Mean Gradient is calc from the VTI across the MV as measured with CW doppler. What are the mild - severe values for mean gradient?
Mild 0-5 mmHg, Moderate 5-10mmHg, Severe >10mmHg
How do we label the two major papillary muscles?
Anterolateral (dual blood supply, less prone to ischemic events)
Posteromedial (perfused by RCA)
