The aim of this study was to compare safety and feasibility of a subcutaneous purse-string suture (PSS) with manual compression (MC) to gain hemostasis in patients after multiple femoral venous punctures undergoing electrophysiological procedures on uninterrupted oral anticoagulation (OAK). A total of 784 patients who underwent catheter ablation for atrial fibrillation (n = 564) or (a)typical atrial flutter (n = 220) were assessed. Four hundred sixty-two patients received PSS (58.9%) and 322 patients (41.1%) received MC to gain hemostasis. All patients were on uninterrupted full-dose OAK. During the procedure, weight-adapted heparin was applied. Venous sheath diameter were 8Fr (n = 2)/11.5Fr (n = 1) for left atrial or 8Fr (n = 1)/6Fr (n = 2) for right atrial procedures. No protamine was administered at the end of the procedure. After PSS, patients' had 6 hours of bed rest compared with 10 hours after MC (sheath removal after 4 hours followed by a bandage for 6 hours). PSS was removed the following day. All patients underwent duplex sonography of the access site the following day. Using the PSS, hemostasis was achieved in 453 of 462 patients (98%). MC leads to hemostasis in all 322 patients. No difference was found between the 2 approaches regarding hematomas (<5 cm or >5 cm), arterio-venous fistulas, or pseudoaneurysms. No major complication such as ipsilateral leg ischemia, the need of vascular surgery, or deep vein thrombosis occurred. In conclusion, PSS is a safe and effective way to gain immediate hemostasis after multiple punctures of the femoral vein in patients undergoing catheter ablation on OAK. PSS avoids MC and leads to shorter patient immobilization.
