LA pressure (a ratio ,4.2 is accurate
in identifying patients with filling pressures .15 mm Hg).
However, the E/e´ ratio is not useful.69
Key Point. Mitral stenosis renders the assessment of LV
diastolic function more challenging, but IVRT, TE-e´, and
mitral inflow peak velocity at early and late diastole can
be of value in the semiquantitative prediction of mean LA
pressure.
