Abstract To overcome the limitations of mitral inflow parameters for predicting pulmonary capillary wedge pressure (PCWP), combined indices (with Doppler tissue imaging or color M-mode Doppler) have been developed. This study was aimed to compare the accuracy of these indices to predict PCWP. Sixty-one patients were studied. The best correlations with PCWP were found for indices that combined isovolumic relaxation time with flow propagation velocity (color M-mode) or early diastolic velocity of the lateral mitral annulus (Doppler tissue). Both closely tracked changes in PCWP. The color M-mode-derived index was the most accurate in patients with normal systolic function. (J Am Soc Echocardiogr 2002;15:1245-50.)
