  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subjects with failure but no symptoms (NYHA Class I) or subjects with mild heart failure that only sometimes interferes with daily activities (NYHA Class II)
  • Subjects who have, or are risk of having, a heart beat that is too fast and his/her doctor has determined he/she needs an implantable cardioverter defibrillator (ICD)

Who cannot join

  • Subjects with rapid heart beats in their ventricles (lower chambers of the heart) associated only with reversible causes

About this study

People who have a dangerously fast heart beat, or whose heart is at risk of stopping beating, may be in need of an electronic device called an implantable cardioverter defibrillator (ICD). An ICD is implanted surgically just under the skin in the upper chest area and it sends a strong electrical impulse, or shock, to the heart to return it to a normal rhythm.

The purpose of this study was to evaluate the safety and efficacy of the EnTrust ICD device. A feature of this device allows it to send small, painless electrical impulses (Anti-tachycardia pacing or ATP) to the heart instead of shocking it out of a rhythm that is too fast. Stopping a dangerous heart rhythm this way does not cause any pain whereas a shock to the heart can feel like a punch in the chest. This device also allows the heart to beat on its own when it can and helping it (by pacing, or sending it electrical signals) when it needs help. This feature is important because previously studies have shown that pacing the heart too often can increase the risk for heart failure or for atrial fibrillation (having too rapid of heart beats in the atrium).

This study is now complete and the device has since been approved by the FDA.

What participants receive

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

  • Implantable Cardioverter DefibrillatorDevice

What is being measured

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

  1. Safety and efficacy at three months.

Secondary outcomes (3)
  1. To evaluate how well the device distinguished between arrhythmias originating in the atrium versus those that originate in the ventricle.

  2. To evaluate how well the anti-tachycardia pacing function works.

  3. To observe the overall performance of the device system.

Questions about this trial

What is this clinical trial studying?

A study testing Implantable Cardioverter Defibrillator in people with Ventricular Arrhythmias, run by Medtronic Cardiac Rhythm and Heart Failure at 41 sites in 7 countries.

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 2 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 13 Oct 2006. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 41 sites in United States, Canada, Germany, Austria, Denmark and 2 more countries. 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?

Safety and efficacy at three months.. 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 13 Oct 2006.
