The predictors of pacing capture threshold (PCT) exacerbation after leadless pacemaker implantation remain unknown. We analyzed the predictors of poor PCT by identifying risk factors using multivariate logistic regression analysis for 211 patients with leadless pacemaker implantation. Twenty patients met the criteria for elevated PCT levels and were categorized in the poor PCT group. Multivariate analyses revealed that PCT (P < 0.0001) and pacing impedance (P = 0.03) were independent predictors of PCT exacerbation. Elevated PCT levels and low pacing impedance during leadless pacemaker implantation were potential risk factors for the replacement of leadless pacemakers after the procedure.

Background:Renal dysfunction coexists with other known risk factors of left atrial (LA) structural remodeling, expressed as low-voltage zones (LVZs), and the recurrence of atrial fibrillation (AF) after ablation. This study aimed to determine whether renal dysfunction had an independent effect on the presence of LVZs and recurrence after AF ablation, using propensity score (PS) matching analysis.Methods and Results:448 consecutive patients who underwent their initial AF ablation were enrolled. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, with 126 (28%) patients having CKD. Using PS matching analysis, new subsets (CKD and non-CKD group, n=103 each) were obtained, matched for age, sex, AF type, and LA volume. The presence of LVZs defined as bipolar voltage <0.5 mV was higher in the CKD group than in the non-CKD group (31% vs. 17%, P=0.034). Multivariate analysis showed eGFR was an independent predictor of the presence of LVZs (odds ratio 1.31 per 10-mL/min/1.73 m2decrease, P=0.029). AF-free survival rate was significantly lower in the CKD patients during 20±9 months of follow-up (63% vs. 82%, P=0.019), and eGFR was shown to be an independent predictor of recurrence (hazard ratio 1.29 per 10-mL/min/1.73 m2decrease, P=0.006), but the presence of LVZs did not predict recurrence.Conclusions:Renal dysfunction independently predicted not only the recurrence of AF after ablation but also the presence of LVZs.
