Abstract
To the Editor: The echo Doppler–derived ratio of early transmitral velocity to tissue Doppler mitral annular early diastolic velocity (E/Ea) has recently become an accepted noninvasive method to estimate left ventricular (LV) diastolic pressures for a variety of clinical conditions.1 However, the reliability of this measurement in patients with decompensated heart failure has been questioned in the article by Mullens et al.2 Their study compared pulmonary capillary wedge pressure (PCWP) to E/Ea in consecutive patients with symptomatic heart failure in intensive care and found a poor …
