Key result
Quantitative single plane left ventricular cineangiography volumes correlated well with actual volumes (r=0.967), and mean Vcf was identified as the most sensitive index of abnormal left ventricular function.

Supports EF and mean Vcf for LV assessment on cineangiography; leaves open outcome validation in larger cohorts.

Which ejection phase index from single plane left ventricular cineangiography best discriminates abnormal left ventricular function in infants, children, and adults?
Effect estimate: r=0.967
Mean rate of circumferential fibre shortening (mean Vcf) is a highly sensitive index for discriminating abnormal left ventricular function using single plane cineangiography.
Tynan et al. (1975) conducted an observational in abnormal left ventricular function (n=62). Quantitative single plane left ventricular cineangiography and ejection phase indices vs. Other calculated indices of left ventricular performance was evaluated on Correlation between actual and calculated volumes, and discrimination of abnormal left ventricular function (r=0.967). Quantitative single plane left ventricular cineangiography volumes correlated well with actual volumes (r=0.967), and mean Vcf was identified as the most sensitive index of abnormal left ventricular function.
