4. Management strategy for patients
with mitral stenosis and mild symptoms. Abbreviations: CXR
= chest x-ray, LA = left atrial, MVA = mitral valve area,
PMBV = percutaneous mitral balloon valvotomy, PAP = pulmonary
artery pressure, PAWP = pulmonary artery wedge pressure.
*The committee recognizes that there may be variability
in the measurement of MVA and that the mean transmitral
gradient, PAWP, and PAP should also be taken into consideration.
There is controversy as to whether patients with severe
MS (MVA <1.0 cm2) and severe pulmonary hypertension
(PAP >60-80 mm Hg) should undergo MVR to prevent right ventricular
failure.
