Vascular Closure With a Device Compared to Manual Compression After Atrial Fibrillation Ablation: The LockeT II Study

Who May Qualify: - Must be at least 18 years of age - Be able to provide consent - Presenting for planned procedures that require percutaneous venous punctures, such as atrial fibrillation radiofrequency ablation, and where the physician utilizes a LockeT device or MC to close the wound. Who Should NOT Join This Trial: - Under the age of 18 - Unable to or unwilling to provide consent - Cannot comply with study requirements - Not undergoing procedures that require a percutaneous venous puncture or planned access to the left atrium and/or ventricle - Subjects whose physician does not use LockeT or MC to close the venous puncture. - Patient is currently pregnant, as evidenced by positive urine Beta-HCG. (Urine Beta Human chorionic gonadotropin (HCG) will be checked in all females of the reproductive age group). - If the physician detects a formed hematoma prior to venous closure, that patient will be excluded from the study. Always talk to your doctor about whether this trial is right for you.
