Chapter 6 134 6.3.6 Predictors of recurrence In multivariate analysis, only PV reconnection/DC was associated with a higher incidence of AF recurrence (Table 5). Table 5. Univariate and multivariate cox proportional regression analyses of the predictors of recurrence per patient. Variables Univariate Multivariate Hazard ratio (95% confidence interval) P value Hazard ratio (95% confidence interval) P value Age 0.397 Male Gender 0.119 BMI (kg/m²) 0.782 LA diameter (mm) 0.819 AF duration (months) 0.483 Group 0.152 Reconnection/DC 4.0 [1.465-10.919] 0 .007 4.037 [1.446-11. 271] 0.008 CTI Ablation 0.084 0.096 Diabetes 0.359 AF indicates atrial fibrillation; BMI, body mass index; CTI, cavotricuspid isthmus; LA, left atrium; DC, dormant conduction. 6.3.7 Complications One patient from the 150s group showed persistent phrenic nerve palsy at discharge that was resolved at 1-year follow up. Two patients had complications related to the vascular femoral access, including one patient with a severe bleeding requiring transfusion. In Figure 2 a ‘safety profile’ is made using the number of reconnection/ DC, aborted ablations, phrenic nerve palsy and repeated procedures.
