- Mitral stenosis renders 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 LAP.
- The time interval Ar-A and IVRT/TE-e' ratio may be applied for estimation for prediction of LV filling pressures in patients with MR and normal LVEF, whereas E/e' ratio may be considered only in patients with MR and depressed EF.
- The guidelines in patients without valvular heart disease can be applied to patients with aortic stenosis, irrespective of severity of valvular stenosis. This excludes patients with heavy MAC.
- In patients with severe AR be it acute or chronic, premature closure of mitral valve, diastolic MR, LA enlargement, average E/e' ratio > 14, and TR peak velocity > 2.8 m/sec are consistent with elevated LV filling pressures.
