Risk factors for venous bleeding complication at the femoral puncture site after catheter ablation of atrial fibrillation

Abstract

Abstract Background Venous bleeding complication is often observed after catheter ablation of atrial fibrillation (AF), but the risk factors remain unclear. Methods We retrospectively evaluated 570 consecutive patients who underwent catheter ablation of AF from April 2012 to March 2017. After the procedure, the sheaths were removed, and hemostasis was obtained by manual compression followed by application of rolled gauze with elastic bandage and continuous pressure to the puncture site. We evaluated the risk factors for venous bleeding complications defined as hemorrhage from the puncture site that needed recompression after removal of the elastic bandage and rolled gauze. Results After excluding 11 patients because of missing data, 559 patients (395 [70.7%] men, mean age: 65.6 ± 8.7 years) were included for analysis. Venous bleeding complication was observed in 213 patients (38.1%). In the multivariate logistic regression analysis, low body mass index (BMI; odds ratio [OR] 0.95, 95% CI 0.90‐1.00, P = .04), short compression time (OR 0.77, 95% CI 0.68‐0.88, P < .001), and antiplatelet therapy (OR 1.86, 95% CI 1.09‐3.16, P = .02) were independent risk factors for venous bleeding complication. Conclusions Low BMI, short compression time, and antiplatelet therapy were independent risk factors for venous bleeding complication after catheter ablation of AF. Longer compression time may be needed for patients with low BMI and/or those receiving antiplatelet therapy.
