We assessed the impact of advanced preprocedural imaging on the safety and long\u2010term efficacy of radiofrequency catheter ablation (RCA) for VT, comparing patients with NICM and ischemic cardiomyopathy (ICM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this prospective, single\u2010center study, consecutive patients referred for scar\u2010related VT ablation underwent multidetector computed tomography (MDCT) and late gadolinium enhancement cardiac magnetic resonance (LGE\u2010CMR). Images were segmented with ADAS 3D software and integrated into mapping systems. Substrate map collection targeted the imaging\u2010predicted area of interest and the ablation aimed at eliminating all local abnormal ventricular activities. Procedural safety was evaluated with 30\u2010day mortality. Long\u2010term efficacy was assessed by survival free from appropriate ICD shocks at 36\u2009months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      102 patients were included (67\u2009\u00b1\u200911\u2009years, 94% male; 75 ICM, 27 NICM).
