Vascular Closure With a Device Compared to Manual Compression After Atrial Fibrillation Ablation: The LockeT II Study
- Conditions
- HemostasisAtrial Fibrillation
- Interventions
- Device: Vascular closure with LockeT device
- Registration Number
- NCT06078735
- Lead Sponsor
- Kansas City Heart Rhythm Research Foundation
- Brief Summary
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.
- 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.
Recruitment & Eligibility
- Status

- Sex
- All
- Target Recruitment
- 110
- 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.
- 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.

- Primary Outcome Measures
Name Time Method Effectiveness of using the LockeT suture retention device 2 Days Effectiveness of using the LockeT suture retention device to gain hemostasis after venous procedures as compared to standard Manual Compression (MC) will be assessed.
- Secondary Outcome Measures
Name Time Method Patient, physician, and nursing staff benefits 2 Days Patient, physician, and nursing staff benefits of the LockeT device will be assessed via LockeT device questionnaire with a scale of 1 to 5, 1 strongly disagree and 5 strongly agree.
Safety of LockeT device 2 Days Safety of LockeT device will be assessed by the incidence of adverse events, including but not limited to: vascular complications, like atrioventricular (AV) fistula, retroperitoneal bleed, surgical exploration of the groin (thrombin injection, open surgery or ligation); need for blood transfusion, defined as a 2 gm post-procedure drop in hemoglobin, or symptoms of anemia,).
Comparison of Manual Compression labor cost and Locket device cost 2 Days Manual Compression labor cost and Locket device cost will be compared
Patient discomfort with Locket device 2 Days Pain discomfort will be assessed via Locket device questionnaire with a scale of 1 to 5, 1 strongly disagree and 5 strongly agree.
Incidence of hematoma/ecchymosis 2 Days The incidence of hematoma/ecchymosis post-procedure will be assessed.
