Introduction: Catheter ablation (CA) of frequent idiopathic premature ventricular beats (iPVBs) was understood to improve hemodynamics. The objective of present study is to clarify the effect of CA of iPVBs for renal function.
Methods: Forty-six patients (26 men; mean age 60 ± 13 years) undergone CA of iPVBs in our hospital were enrolled. We divided the patients into two groups. Group 1 (n=34) is patients with iPVBs that could be eliminated successfully (percentage of PVBs after CA a day < 2%), and Group 2 (n=12) is patients with unsuccessful CA. Basic clinical parameters and estimated glomerular filtration rate (eGFR) as an index of renal function before and after CA were studied retrospectively.
Results: : Baseline characteristics did not differ between the groups significantly without the origin of iPVBs. (Table) In Group 1, eGFR was improved after CA significantly (65.4 ± 14.9 vs 73.2 ± 15.6 , p=0.037) and eGFR before and after ablation were not different in Group 2 (63.5 ± 15.6 vs 62.1 ± 16.4 , p=0.84 ), (Figure)
Conclusions: Elimination of frequent iPVBs by CA could improve renal function.
