Vorticity is a novel index that reflects diastolic function of left ventricle. The size of the ventricle can influence the ventricular diastolic blood flow.
Echocardiography was performed on 58 dogs and were assessd the effect of ventricular size on diastolic and diastolic intracardiac blood flow using vector flow mapping and intraventricular pressure gradient (IVPG). The result showed that vorticity is affected by the size of the left ventricle independently of other factors. It was suggested that the size of the ventricles should be considered in order to properly assess the hemodynamic status of each individual using vorticity and IVPD.
