Quantitative analysis (to compare with the results of analysis represented in Fig. 3), by echo-particle imaging velocimetry of the orientation angle (φ) of the global hemodynamic forces exchanged between blood and surrounding tissues during acute study (post-cardiac resynchronization therapy 6-month follow-up). a Two-dimensional transthoracic echocardiogram high-temporal resolution contrast echocardiography is performed by three-chamber apical view approach (see Additional file 10: Video S10 interventricular − 50 ms SONOVUE 6-month follow-up). b The polar histogram showed with setting interventricular delay − 50 ms the most aligned intraventricular forces that were partially dominated by the longitudinal path of pressure gradient (lower φ, value 43.1°).
