StatSeal vs Figure-of-Eight Suture for Vascular Closure in AF Ablation

December 22, 2025 updated by: Mid and South Essex NHS Foundation Trust

This study, titled aims to compare two vascular closure techniques after catheter ablation for atrial fibrillation (AF). Catheter ablation is a common procedure used to treat AF, but after the procedure, It is important to close the access site in the blood vessel to prevent bleeding. This study will evaluate whether the StatSeal device, a haemostatic disc, can help patients recover more quickly compared to the traditional figure-of-eight suture technique.

The primary objective of the study is to determine whether StatSeal reduces the time it takes for patients to start walking after the procedure (known as Time to Ambulation). Secondary objectives include comparing the time to complete haemostasis, discharge eligibility, incidence of adverse events, and patient comfort between the two techniques.

Participants in the study will be randomly assigned to receive either the StatSeal device or the figure-of-eight suture after their AF ablation procedure. The study will recruit 160 participants across multiple hospital sites, with 80 participants in each group. Both techniques are standard methods, and participants will be closely monitored for safety throughout the study.

By comparing these two closure techniques, the study aims to improve the recovery process for patients undergoing AF ablation and provide evidence on which method leads to better outcomes and patient experiences.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to ambulation (TTA) after sheath removal
Time Frame: 1 day
Time to ambulation is defined as the elapsed time between removal of the final sheath and the moment when the patient can stand and walk 20 feet without evidence of venous re-bleeding from the femoral access site.
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to haemostasis
Time Frame: 1 day
time elapsed between removal of the vascular sheath and first observed and confirmed venous haemostasis, for each access site
1 day
Time to discharge eligibility
Time Frame: 1 day
time elapsed between removal of the final sheath and when the patient is eligible for hospital discharge based solely on the assessment of the access site, as determined by the medical team
1 day
Time to discharge
Time Frame: 1 day
time elapsed between removal of the final sheath and when the patient was discharged from the institution
1 day
Incidence of major periprocedural adverse events
Time Frame: 1 day
defined as adverse events until hospital discharge requiring medical intervention.
1 day
Incidence of major adverse events
Time Frame: 30 days
Major adverse events are defined as complications requiring medical intervention or hospitalisation
30 days
Incidence of minor adverse events
Time Frame: 30 days
Minor adverse events are defined as AEs not requiring medical intervention.
30 days
Comparison of EuroQol EQ-5D-5L
Time Frame: 30 days
Comparison of EuroQol 5-level EQ-5D score. The score is made up of two parts: the EQ-5D descriptive system and the EQ visual analogue scale (EQ-VAS). The first part covers five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension offers five response options (no problems, slight problems, moderate problems, severe problems, and extreme problems), from which an EQ-5D index score is calculated, ranging from 0 (death) to 1 (perfect health). The EQ-VAS assesses an individual's self-perceived health for the day on a vertical scale from 0 (worst imaginable health) to 100 (best imaginable health), where participants mark their current health status.
