A new model for the quantitative analysis of left ventricular regional function


, : A new model for the quantitative analysis of left ventricular regional function. Schweizerische Medizinische Wochenschrift 114(45): 1598-1601

A computer-assisted model for quantitative analysis of left ventricular segmental wall motion is presented. In contrast to standard rectangular and radial chord methods, no coordinate and reference system is used. Normal wall motion of 5 ventricular segments in the RAO projection was evaluated in 20 patients with normal ventriculograms. Segmental wall motion abnormalities after myocardial infarction were then analyzed by the computer-assisted method in 60 patients and the results compared with the visual assessment of an experienced cardiologist as standard reference. 96% of all segments with normal motion, 95% of all hypokinetic segments and 100% of all dyskinetic segments were correctly identified by computer analysis. Akinesia, however, was detected only in 25% of all cases and misinterpreted chiefly as hypokinesia. Further refinement of the software should improve detection of akinesia and classification of hypokinesia.
