Figure legends
Figure 1 – Internal and external anchor deployment.
Figure 2 – A & B – apical 2- & 4-chamber views, respectively, showing LV dilatation and bulbous apex, with apical, distal anterior and septal wall thinning; C & D–apical 4-chamber view showing apical thrombus without (C) and with contrast-enhancement (D)
Figure 3 – A & B – 2 & 4 chamber LGE views showing LV dilatation and transmural scar in distal antero-septal walls and apex; C & D – Large LV apical thrombus
Figure 4 – Contrast-enhanced multiphasic CT scan – 2- (A) & 4-chamber view (B), demonstrating LV dilatation, anterior and apical wall thinning (blue arrows) and LV apical thrombus (*);C – short axis view of the same patient, demonstrating antero-septal wall thinning (blue arrows); D – 3D volume rendering contrast-enhanced CT scan of a patient with extensive LV antero-lateral scar and wall calcification (white arrows). Pacemaker leads are illustrated in (B) and (D) (ǂ).
Figure 5 – CT-Scan – A – case planning according to scar location on 3D volume rendering; B – RV-LV basal “Antonius” stitch, addressing additional antero-lateral and septal components of the scar; C – expected result of pre-operative LGE CMR (red line). Anchors are represented by yellow rectangles.
Figure 6 – A – pre-operative 3D volume rendering CT of a patient with distal antero-lateral and apical scar; B – post-operative 3D volume rendering CT of the same patient with 3 LV-LV anchor pairs deployed, demonstrating full scar exclusion; C – post-operative LV ventriculography of patient with lateral LV scar, treated with 4 linear LV-LV anchor pairs
