Trial summary

Temporary cardiac pacing with active-fixation leads (TPAFL) using a reusable permanent pacemaker generator has been shown to be safer than lead systems without fixation. However, TPAFL requires the off-label (non-certificated) use of Pacemaker leads and generators. Read more about this study

About this study

Temporary cardiac pacing with active-fixation leads (TPAFL) using a reusable permanent pacemaker generator has been shown to be safer than lead systems without fixation. However, TPAFL requires the off-label (non-certificated) use of Pacemaker leads and generators. It is designed a fastening system to ensure the safety and efficacy of the procedure: the KronoSafe System®. The aim of this study is to demonstrate the safety and effectiveness of the KronoSafe System® for temporary pacing in a series of patients receiving TPAFL.

Model description
The study will be carried out in an Arrhythmia Unit or Intensive Care Unit. Patients who need urgent temporary cardiac pacing due to bradycardia, or elective pacing to prevent heart rhythm disturbances during high-risk arrhythmia interventions, such as transcatheter aortic valve implantation (TAVR), alcoholic septal ablations, etc., will be included. After the temporary pacemaker implantation with active fixation electrode in a correct way, the KronoSafe® external pacemaker fixation system will be placed. The correct functioning of the system (R wave detection, lead impedance and right ventricle threshold) will be checked at 24 hours and every other day until the end of cardiac stimulation. During temporary pacing, associated complications are going to be recorded: lead displacement, capture or sensing failure, generator or lead detachment, and cardiac perforation.

Questions about this trial

What is this clinical trial studying?

A study testing KronoSafe® System in people with Arrythmia and Bradycardia, run by ICU Medical Technologies S.L. at 2 sites in Spain.

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 7 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 20 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Spain. 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?

Ventricular R wave detection (time frame: Immediately after the procedure of lead implantation). The study lists 57 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05351658, which also lists 5 linked publications.

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 20 Apr 2025.
