LVEF modifications with and without ablation In order to analyze the impact of CTIA on LVEF, we could show a highly significant impact of CTIA on LVEF in the ablation group ( n = 48) at 1 year (LVEF: 50.00 ± 20.00%; p < 0.001) and at 2 years (LVEF: 50.00 ± 20.00%; p < 0.001), respectively, compared with pre-intervention LVEF levels (LVEF: 35.00 ± 10.00%).
