Abstract
Background The inflow propagation velocity (Vprop) of the early filling wave has been proposed as an accurate marker of left ventricular (LV) diastolic function [1]. Traditionally, Color M-mode echo Doppler is used for Vprop-assessment. However, this method has not been validated against an alternative modality such as velocity-encoded (VE) MRI for assessing Vprop. The purpose of this study was to compare Vprop assessed from high temporal VE MRI with Color M-mode echo Doppler in patients with ischemic cardiomyopathy. Methods

The inflow propagation velocity (Vprop) of the early filling wave has been proposed as an accurate marker of left ventricular (LV) diastolic function [1]
The purpose of this study was to compare Vprop assessed from high temporal VE MRI with Color M-mode echo Doppler in patients with ischemic cardiomyopathy
In 36 patients with known ischemic cardiomyopathy and impaired LV systolic function, one-directional time-resolved VE MRI was performed on 1.5T MRI (Philips) to acquire the LV inflow pattern
