Pulse wave generation during left ventricular (LV) contraction and subsequent wave reflections directly affect the ventricular workload.
The aim of this study was to obtain new information on regional LV wall motion corresponding to the propagation of reflected waves on ventricular segments.
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.
The results provide new insights on the propagation of reflected waves on ventricular segments and their effects on ventricular motion patterns in health and disease.
