Safety Outcomes
Mortality at 30-days after index-procedure was similar between NC-ABL and C-ABL (10 vs. 1 for NC-ABL and C-ABL, respectively, P=0.777). The complication rate was not different between both groups (10.3% vs. 15.1% respectively, P=0.336). In a sub-group analysis, the C-ABL group had more pericardial effusions (2% vs 9%, P=0.014) and right ventricular punctures (1% vs 7%, P=0.017). There were 2 strokes in the NC-ABL group and non in the C-ABL group (P=1.000). Two patients in the NC-ABL group developed complete heart block vs. 1 in the C-ABL group (P=1.000).
