About this study

Official title: Evaluation of Left Ventricular Pacing Vectors Use in Phrenic Nerve Stimulation Management and Left Ventricular Parameters Adjustment

Evaluation of three left ventricular pacing polarities effectiveness to narrow phrenic nerve stimulation.

Read the detailed description

The primary endpoint of the study aims at demonstrating that the three left ventricular polarities in the Cardiac Resynchronisation Therapy-Defibrillator could bypass phrenic nerve stimulation at least in 90% of implants.

Success was defined as an absence of phrenic nerve stimulation (threshold > 7V) or in case of phrenic nerve stimulation occurrence (threshold < 7V), as the resolution of the phrenic nerve stimulation by reprogramming one of the 3 left ventricular pacing polarities available in the device : left ventricular tip- left ventricular ring (bipolar), left ventricular tip- right ventricular ring (pseudo-bipolar) and left ventricular ring-right ventricular coil.

Any occurrence of phrenic nerve stimulation without resolution by reprogramming was considered as a failure.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cardiac Resynchronization Therapy -Defibrillator (range PARADYM, LivaNova, Clamart, France)Device

    Patients were implanted with a Cardiac Resynchronization Therapy -Defibrillator (model PARADYM RF SONR CRT-D 9770 or PARADYM RF CRT-D 9750, Sorin) having 3 left ventricular polarities. The choice of the right atrial, right ventricular and bipolar left ventricular leads was left to investigators' discretion.

What is being measured

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

  1. Phrenic nerve stimulation measurement

    The presence of phrenic nerve stimulation at 10 Volt, using a pacing system analyzer

    Measured: The presence of phrenic nerve stimulation will be assessed at implant.

Questions about this trial

What is this clinical trial studying?

A study testing Cardiac Resynchronization Therapy -Defibrillator (range PARADYM, LivaNova, Clamart, France) in people with Heart Failure, run by LivaNova at 12 sites in France.

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 3 inclusion and 8 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 25 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in France. 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?

Phrenic nerve stimulation measurement (time frame: The presence of phrenic nerve stimulation will be assessed at implant.). 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 25 Apr 2017.
