Vascular Closure With a Device Compared to Manual Compression After Atrial Fibrillation Ablation: The LockeT II Study
Purpose
The LockeT II study is a single center, prospective randomized study. It is intended to study the effectiveness of using LockeT device to gain hemostasis after venous procedures as compared to Manual Compression (MC). Approximately 110 patients will be enrolled.
Conditions
- Atrial Fibrillation
- Hemostasis
Eligibility
- Eligible Ages
- Over 18 Years
- Eligible Sex
- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- 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.
Exclusion Criteria
- 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.

Detailed Description
The volume of catheter ablation procedures for the treatment of atrial fibrillation and other arrhythmias are on the rise in the United States and worldwide. Despite decrease in complication rates due to refinement in ablation tools and techniques, achieving vascular hemostasis following large-bore sheath femoral access remains a challenge. Thus, MC remains the current standard of care. However, MC requires up to 8 hours of prolonged bedrest, which is associated with longer length of stay and complications from indwelling catheters. Another method of vascular closure is the figure-of-eight (FoE) stitch - a subcutaneous suture that has been evaluated to achieve homeostasis following major cardiovascular procedures. In recent years, invasive, vascular closure devices have become popular. However, results continue to suggest that the risk versus benefit has not been definitively demonstrated. Instead, the LockeT is a new suture retention device designed to closely mimic manual compression by distributing the tension of a FoE stitch over a larger surface area. In such a way, patients can have the benefits of MC without a healthcare professional to stand bedside.
