Abstract

BACKGROUND: Many patients undergoing ventricular tachycardia (VT) or premature ventricular complex (PVC) ablation receive anti-thrombotic medications. Their uninterrupted use has the potential to affect complication rates. We assessed the incidence of complications in a large cohort of patients undergoing these procedures, according to anti-thrombotic medication use. METHODS: From June 2014 to June 2016, 201 VT and PVC ablations were performed at a single center. We allocated patients to three groups: A - anticoagulation group (INR≥1.5 or NOAC or full dose LMW heparin on day of procedure); B - antithrombotic group (antiplatelet therapy and/or prophylactic LMW heparin on day of procedure); C - no anti-thrombotics group. We assessed peri-procedural complication rates in each group. Multivariable analysis was performed. RESULTS: Group A (47 patients) had an 8.5% procedural complication rate: one stroke, one pseudoaneurysm, one femoral artery occlusion and one access site hematoma. In this group, 37 patients had femoral arterial and 18 had epicardial access. In Group B (46 patients) the complication rate was 6.5%: two cardiac tamponades and one pericardial effusion without compromise. Group C (108 patients) had a 5.6% complication rate: three cardiac tamponades (with one peri-procedural death and one concomitant gastric vessel injury), one pericardial effusion without compromise, one stomach perforation and two access site hematomas. Multivariable analysis did not show any significant predictors of complications, though age approached significance. CONCLUSIONS: Complication rates were not significantly different between groups. These findings suggest that VT and PVC ablation can be performed safely in patients with uninterrupted anti-thrombotic medications. This article is protected by copyright. All rights reserved.
