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.

Vortex strength assessment may support LV evaluation in HF; leaves open whether it improves risk stratification beyond standard measures.
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.
