About this study

The purpose of this clinical study is to observe the safety and efficacy of the multi-vector left ventricular (LV) lead in Chinese patients that are indicated for Cardiac Resynchronization Therapy (CRT).

Read the detailed description

This is a multi-center, non-randomized observational study.

The total duration of the study is expected to be 2.5 years. The clinical study will be conducted in no more than 15 centers in China. Approximately 120 subjects will be enrolled in this study. Subjects will be followed up at 3, 6, 12 months and every 6 months afterwards. All subjects need to be followed for at least 6 months.

Being tested
CRT

What participants receive

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

  • CRTDevice

    The study will include the Quartet™ family of left heart leads or any newer St. Jude Medical quadripolar CRT systems, including CRT-P systems, that China Food and Drug Administration (CFDA) might approve in the future

What is being measured

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

  1. The Number of Participants With LV Lead-related Serious Adverse Device Effects (SADEs)

    The primary safety endpoint is the number of participants with LV lead-related SADEs compared to the total number of analyzed participants.

    Measured: From implantation to 6 months after implant procedure.

Secondary outcomes (3)
  1. The Number of Participants With Effective LV Pacing

    The effectiveness endpoint is the number of participants with effective LV pacing compared to the total number of analyzed participants. The following must be met to be considered effective LV pacing:

    • Pacing threshold (immediately after implant): for pacing threshold at a pulse width of 0.5 ms, the voltage must be ≤3.5 Voltage (V) in any LV lead vector.
    • Pacing stability (pre-discharge, 3 months and 6 months after implant): for pacing threshold at a pulse width of 0.5 ms, the voltage must be ≤6.0V in any LV lead vector.
    • Pacing impedance (immediately after implant): Impedance value in any LV lead vector must be in the normal range of 200-2000 ohm (Ω).
    • Table 9: Impedance stability (pre-discharge, 3 months and 6 months after implant): Impedance value in any LV lead vector must be in the normal range of 200-2000Ω.

    Measured: 6 months

  2. The Number of Participants in Each NYHA Functional Class

    This secondary objective is to count the number of participants in each NYHA functional class at 6 months; NYHA classification is determined by a physician and measures the severity of a patient's heart failure by evaluating heart failure symptoms and limitations. Class I patients have mild heart failure symptoms, while patients with Class IV have severe symptoms.

    Measured: 6 months

  3. The Intrinsic QRS Duration of Participants

    This secondary objective is to measure the intrinsic QRS duration of participants at 6 months.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Heart Failure, run by Abbott Medical Devices at 14 sites in China.

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 4 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 18 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in China. 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?

Yes. Results are posted in the registry (first posted 18 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Number of Participants With LV Lead-related Serious Adverse Device Effects (SADEs) (time frame: From implantation to 6 months after implant procedure.). 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 18 Nov 2020.
