About this study

Death and vascular tears occur in up to 1% of the patients undergoing lead extraction procedures. These complications are due to abnormal force vectors during the procedure. The investigators postulate that use of bidirectional traction (superior and inferior directions) and feedback from a digital force gauge is associated with minimal lead displacement compared to conventional lead extraction. Lead displacement is an indirect risk factor for potentially fatal lead extraction complications

Read the detailed description

Use of force no greater than 8 pounds of tension will improve lead extraction and minimize lead displacement compared to current standard of care methods which do not limit the force applied. Among subjects undergoing lead extraction procedures for CIED infection, bidirectional rail (superior and inferior) and traction force objective feedback using Force gauge is associated with minimal displacement (<1cm) of the leads (surrogate marker) on fluoroscopy compared to conventional lead extraction. • The research nature of the protocol is explicitly explained to the patient and an informed consent is explained obtained from the patient prior to the procedure. Only patients with CIED infections requiring lead extraction are enrolled in the study. Patients are risk stratified based on our current risk stratifications scheme. Multiple superior and inferior venous accesses are obtained during the procedure. The leads are prepared using locking stylets. Baseline fluoroscopic image of the position of the leads is stored. A deflectable sheath and traction forceps are deployed from the groin to provide downward rail in the force feedback arm. Locking stylet from the lead is in turn attached to a Force gauge (McMaster-Carr Santa Fe Springs, CA). The procedure is performed using continuous fluoroscopic image save tool during the procedure for post procedural viewing and analysis. The patients are randomized to the active arm (to keep force around 8 lb) or the control arm (tactile force discretion based on the operator. The investigator is blinded to the force gauge reading for half of the patients enrolled in the study. For the other half of the patients, the operator optimizes the force to prevent overexertion (<8-9 pounds). Three point along the lead course evaluated during the study. Position of downward turn of the lead in the SVC, heel of the lead (only in case of RV lead) and the lead tip positions are evaluated. The investigators postulate that there will be at least 5 cine-fluoroscopic views per every lead. The investigators hypothesize that use of bidirectional rail and force feedback is associated with minimal displacement of the lead on fluoroscopy.

Study groupRoleWhat they receive
InterventionActive comparatorUse of bidirectional rail (superior and inferior approaches) and force sensing using a force gauge to optimize Force application to less than 8 lbs during the extraction procedure.

ControlNo interventionConventional lead extraction procedures using a superior approach is performed by experienced operators. Although force information is available the operators are blinded to the information. Inferior rail is left to the discretion of the operator.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fluoroscopic lead displacement

    The primary objective of the study is to evaluate the effect of traction force as measured by a digital force gauge on fluoroscopic lead displacement during lead extraction procedures. The investigators hypothesize that the lead displacement on fluoroscopy will be less than 1 cm when the traction force is limited to less than 8 lb.

    Measured: Intra-procedure measurements

Questions about this trial

What is this clinical trial studying?

A study testing Force gauge in people with Cardiac Implantable Electronic Device Infection and Cardiovascular Infections, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fluoroscopic lead displacement (time frame: Intra-procedure measurements). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2022.
