Results:
In 20 sample echocardiograms, the edited autostrain GLS measurements
determined by two different clinicians demonstrated minimal
inter- and intra-rater GLS
variability, r=0.90 and r=0.95, respectively.
Our population of 57 patients was composed of 55% female, 12.3%
functional mitral regurgitation (FMR), 61.4% degenerative mitral
regurgitation (DMR) and 26.3% mixed mitral regurgitation (MMR). A
reduction in EDV was demonstrated in 38 patients (67%); the pre- GLS
averaged 12.5% (SD 4.2) mean, 12.4% median (Table I).
