Figure Lengend Snippet: Electroanatomical mapping. a Case I: LAO caudal projection of an ultra-high-density activation map (EnSite NavX and Advisor HD-grid, Abbott Medical, MN, USA) of sustained ventricular tachycardia displaying earliest activation ( white spots ) at the anterior apex of the left ventricle close to the insertion of the LVAD cannula. Black line describes the interdisciplinarily specified target area. b Case II: RAO projection of an ultra-high-density voltage map (Carto 3, Biosense Webster, Diamond Bar, Ca, USA) with diffuse left ventricular low-voltage areas ( red color ). White lines delineate LVAD cannula; the yellow dashed circle indicates the possible target area, the yellow dashed line depicts the area of last failed catheter ablation
Article Snippet: An electroanatomical mapping procedure (CARTO 3; Biosense Webster Inc., Diamond Bar, CA, USA) revealed low-voltage-areas in the inferolateral areas of the left ventricle, reaching towards the LVAD cannula insertion (Fig. b).
