Background— The ratio of early transmitral velocity to tissue Doppler mitral annular early diastolic velocity (E/Ea) has been correlated with pulmonary capillary wedge pressure (PCWP) in a wide variety of cardiac conditions. The objective of this study was to determine the reliability of mitral E/Ea for predicting PCWP in patients admitted for advanced decompensated heart failure.
Methods and Results— Prospective consecutive patients with advanced decompensated heart failure (ejection fraction 
30%, New York Heart Association class III to IV symptoms) underwent simultaneous echocardiographic and hemodynamic evaluation on admission and after 48 hours of intensive medical therapy. A total of 106 patients were included (mean age, 57±12 years; ejection fraction, 24±8%; PCWP, 21±7 mm Hg; mitral E/Ea ratio, 20±12). No correlation was found between mitral E/Ea ratio and PCWP, particularly in those with larger left ventricular volumes, more impaired cardiac indexes, and the presence of cardiac resynchronization therapy. Overall, the mitral E/Ea ratio was similar among patients with PCWP >18 and 18 mm Hg, and sensitivity and specificity for mitral E/Ea ratio >15 to identify a PCWP >18 mm Hg were 66% and 50%, respectively. Contrary to prior reports, we did not observe any direct association between changes in PCWP and changes in mitral E/Ea ratio.
Conclusion— In decompensated patients with advanced systolic heart failure, tissue Doppler–derived mitral E/Ea ratio may not be as reliable in predicting intracardiac filling pressures, particularly in those with larger LV volumes, more impaired cardiac indices, and the presence of cardiac resynchronization therapy.
