Trial summary

Transesophageal echocardiography is used to monitor cardiac wall motion at various time points during open-heart surgery. After surgery, the measurements are made at various time points by transthoracic echocardiography. The CS1 system enables continuous, direct measurement of cardiac wall motion.

About this study

Official title: Open Clinical Investigation to Assess Performance of a Temporary Epicardial Pace Wire With Integrated Sensor for Continuous Postoperative Monitoring of Myocardial Function After Heart Surgery Compared to Ultrasound

Transesophageal echocardiography is used to monitor cardiac wall motion at various time points during open-heart surgery. After surgery, the measurements are made at various time points by transthoracic echocardiography.

The CS1 system enables continuous, direct measurement of cardiac wall motion. This is achieved through use of temporary pacemaker wires incorporating a motion detector called an accelerometer. Use of TMEs during and after open-heart surgery is part of the normal clinical routine. Continuous monitoring of cardiac wall motion during and after surgery can quickly highlight the need for medical intervention with cardiac drugs and allow very early detection of potentially serious complications leading to abnormal cardiac wall motion.

Cardiac wall motion activity registered by the CS1 system and echocardiography at specific time points during and after surgery will be analyzed to see how well they compare.

Read the detailed description

Echocardiography is currently the most important and most widely used tool in cardiology besides electrocardiography (ECG). It is reliable for assessing all stages of cardiovascular disease, and it is commonly used to detect heart (cardiac) wall motion dysfunction during and after open-heart surgery.

During open-heart surgery, transesophageal echocardiography (when the echocardiography sensor is introduced into the esophagus) is used to monitor cardiac wall motion at various time points during surgery. After surgery, the measurements are made at various time points by transthoracic echocardiography (when the echocardiography sensor is placed on the chest wall).

Use of the CS1 system enables continuous, direct measurements of cardiac wall motion. This is achieved through use of temporary pacemaker wires (also called temporary myocardial electrodes or TMEs) incorporating a motion detector called an accelerometer. Use of TMEs during and after open-heart surgery is part of the normal clinical routine. Continuous monitoring of cardiac wall motion during the surgery and the post-surgical recovery period can, for example, quickly highlight the need for medical intervention with cardiac drugs and allow very early detection of potentially serious complications such as ischemia (heart muscle is not receiving enough oxygen) and myocardial dysfunction (cardiac wall motion appears abnormal).

The key feature of the CS1 system is that the cardiac wall motion activity registered by the novel TMEs incorporating the accelerometer are displayed visually on a standard medical monitor and synchronized with the patient's ECG data. These data can easily be viewed by medical staff to check if the patient's condition is satisfactory or whether medical intervention is needed.

In the study, the CS1 system will be used in addition to the standard monitoring procedures that include ECG, blood pressures and intermittent echocardiography. Cardiac wall motion activity registered by the CS1 system and echocardiography at specific time points during and after surgery will be analyzed to see how well they compare.

What participants receive

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

  • CS1 SystemDevice

    Placement of CS1, a temporary bipolar myocardial electrode (TME) with an integrated motion sensor (accelerometer), on the left ventricle and externalization of the associated leads through the chest wall during open-heart surgery. CS1 will remain in place for up to 7 days after surgery and closure of the chest wall.

What is being measured

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

  1. Change from Baseline Peak Systolic Velocity (PSV) after increasing heart rate by 25 percent

    Correlation between relative changes in PSVs measured by CS1 and echocardiography

    Measured: After surgery: before extubation, while patient is in the intensive care unit (ICU)

  2. Change from Baseline PSV after increasing heart rate by 25 percent

    Correlation between relative changes in PSVs measured by CS1 and echocardiography

    Measured: After surgery: after extubation and removal of drains, before patient is transferred from ICU to general ward

Secondary outcomes (3)
  1. Adverse Events

    Incidence of non-serious and serious adverse events rated for causality

    Measured: Up to 30 days after surgery

  2. Adverse Device Effects

    Incidence of non-serious and serious adverse device-related effects

    Measured: Up to removal of device at a maximum of 7 days after surgery

  3. Device Deficiencies

    Incidence of device deficiencies

    Measured: Up to removal of device at a maximum of 7 days after surgery

Questions about this trial

What is this clinical trial studying?

A study testing CS1 System in people with Cardiac Disease and Myocardial Dysfunction, run by Cardiaccs AS at 1 site in Norway.

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 6 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: status not confirmed, as of the sponsor's last update on 16 Feb 2024. 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 Norway. 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?

Results are not available in the source record.

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?

Change from Baseline Peak Systolic Velocity (PSV) after increasing heart rate by 25 percent (time frame: After surgery: before extubation, while patient is in the intensive care unit (ICU)). The study lists 2 primary outcomes in all. 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 16 Feb 2024; AzTrials last refreshed its copy on 27 Oct 2026.
