New details of reflected pressure wave propagation on left ventricular segments

Methods The regional ventricular wall motion was investigated in two groups of healthy volunteers between the ages of 23 ± 3 and 66 ± 7 years old respectively, using navigator gated tissue phase mapping. The left ventricle was divided into 16 segments (six basal, six middle and four apical) and regional wall motion was studied in high temporal detail. The results were also compared with those obtained in one patient with peripheral vascular disease and in a second patient with a massive LV scar.
