Abstract
Immediate hemostasis following removal of sheaths is essential to prevent access site complications after atrial fibrillation (AF) ablation. Despite various precautions to achieve complete hemostasis in a safe and effective manner, no standard approach is present yet. We aimed to compare the efficacy and safety of standard vs modified figure-of-eight (sFoE vs mFoE) suture for immediate venous hemostasis after cryoballoon (CB) AF ablation. A total of 150 patients who underwent CB catheter ablation were sequentially allocated to either sFoE (n = 75) or mFoE (n = 75) suture to achieve immediate venous hemostasis at right femoral access site after 15 Fr sheath removal. A "three-way stopcock" was used in the mFoE group rather than tying the knot as in a sFoE group. Demographics, clinical and procedural data, and access site complications were recorded. Immediate haemostasis was achieved in all patients (n = 75) with mFoE suture as compared to 90.7% (n = 68) of sFoE suture group (P < .001). Light manual pressure of ≤1 min was required in five patients (6.7%) due to looseness and conventional manual compression because of the snapped silk suture during knotting was required in two patients (2.6%) in the sFoE group. Time to hemostasis was shorter in the mFoE group (P < .001), but time to ambulation and time to discharge were similar in both groups (P > .05). Although no minor or major access site complication has occurred in the mFoE group, in-hospital rebleeding (n = 2, 2.7%) and early local access site infection (n = 2, 2.7%) were observed in the sFoE group. The mFoE suture using three-way stopcock is an available, effective, maybe safe, and time- and cost-saving alternative technique to achieve immediate hemostasis after removal of 15 Fr right femoral venous sheath in patients undergoing cryoablation.
