Key result
Pulsed Doppler echocardiography showed no significant differences compared to cineangiography for peak filling rate (296 vs 283 ml/sec), normalized peak filling rate, and half filling fraction.
Why the study?
Does pulsed Doppler echocardiography accurately measure left ventricular diastolic filling parameters compared to cineangiography?
Observational (n=30)
Does pulsed Doppler echocardiography accurately measure left ventricular diastolic filling parameters compared to cineangiography?
Absolute Event Rate: 296% vs 283%
Pulsed Doppler echocardiography provides comparable measurements of left ventricular diastolic filling parameters to invasive cineangiography.

Supports noninvasive pulsed Doppler echocardiography for LV diastolic filling; leaves open prospective validation versus cineangiography.
Rokey et al. (1985) conducted an observational in Left ventricular filling assessment (n=30). Pulsed Doppler echocardiography vs. Cineangiography was evaluated on Peak filling rate. Pulsed Doppler echocardiography showed no significant differences compared to cineangiography for peak filling rate (296 vs 283 ml/sec), normalized peak filling rate, and half filling fraction.
