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

Figure 2 Left intraventricular vortex flow in a patient with normal cardiac function and a patient with dilated cardiomyopathy. A: An effective vortex in a patient with normal cardiac function. The vortex is formed in the left heart cavity during isovolumic systole to redirect the blood flow and avoid the energy loss caused by the deceleration and then acceleration of the blood flow impulse; B: An ineffective vortex found in dilated cardiomyopathy: The vortex is also present during systole in dilated heart disease, making ejection less efficient.
