Contrast echocardiography assessment of left ventricular vortex strength may serve as a haemodynamic measure of diastole-systole coupling and correlate with clinical outcomes in heart failure.
Our preliminary data suggest that the persistence of vortex from late diastole into IC is a haemodynamic measure of coupling between diastole and systole. The change in VS is correlated with LV mechanical performance and shows association with adverse clinical outcomes seen in HF patients.
Abe et al. (Sun,) studied this question.
