Correlation of the LAA-EF and LAA-FV with the CHA2DS2-VASc score. (a,b) Significant inverse correlations between the CHA2DS2-VASc score and LAA-EF were identified between patients with AFL and those with AFL + PAF. (c,d) An inverse relationship between the CHA2DS2-VASc score and LAA-FV was seen only in patients with isolated AFL not in those with AFL + PAF. LAA-FV, left atrial appendage flow velocity; LAA-EF, left atrial appendage ejection fraction; AFL, atrial flutter; PAF, paroxysmal atrial fibrillation.
