  Figure 1. Ampalzer™ Cardiac plug and Amplazer™ Amulet; SW — stabilising wire.

  Figure 2. A–C. Changes in cardiac function and structure between baseline and follow-up; LA — left atrial; LAVI — left atrial volume indexed to body surface area; E — peak velocity of early diastolic trans-mitral flow; e’ — peak velocity of early diastolic mitral annular motion; DID — difference-in-difference analysis; LAAC — left atrial appendage closure.

  Figure 3. A, B. Correlation between cardiac function and configuration changes with corresponding independent predictors; LAVI — left atrial volume indexed body surface area; e — peak velocity of early diastolic transmitral flow; e’ — peak velocity of early diastolic mitral annular motion; LAD — left atrial dimension; LVPWd — left ventricular posterior wall thickness at end diastole; ΔLAVI = follow-up LAVI – baseline LAVI; E/e’ = follow-up E/e’ – baseline E/e’.
