Value of clinical applications of differential pressure and relative pressure imaging in the left ventricle

Figure 3 Relative pressure imaging of isovolumic systolic to early diastolic phase. The first image shows early systole with apical high pressure ejection flow. The second image shows isovolumic diastole. The left ventricle dilates with mitral valve closure, and low pressure appears at the apex. The third image shows early diastole with continued apical low pressure.
