Spectroscopic Assessment of Intramyocardial Oxygen Saturation During Open-Heart Surgery (ECS)

August 20, 2026 updated by: Spectrocor

The goal of this observational study is to test in the safety and performance of intraoperative myocardial spectroscopic measurement in open-heart surgery patients

The main questions it aims to answer are:

  • The Devices can record myocardial spectrometric data for analysis, and
  • How these measures correlate with the occurring events, procedures, and clinical parameters during the operation.
  • Number of participants with device-related adverse events as assessed by CTCAE v4.0

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study design is based on measuring the depth of ischemia during the operation, which is compared to the intraoperative and postoperative morbidity of the patient, especially to the dysfunction of the heart. A qualified and experienced Monitor is assigned for the study to oversee and document the progress of the trial. The Monitor ensures the trial performance in accordance with the Protocol and Good Clinical Practice (GCP). The trial team conforms to ISO 13485 quality standards and ISO 14155 GCP. Processes included in the monitoring activities are documented in the quality management system. Below are described the summaries of all these activities. Source data will be collected and transferred into the electronic CRFs by site staff, and the collected data quality and the conformity to the Good Clinical Practice will be assessed by monitoring. Based on a risk assessment performed, a Data Monitoring Committee shall not be established. Clinical Research Associate (CRA) is responsible for checking the accuracy and completeness of Case Report Form (CRF) entries, source documents, and other investigation-related records against each other. Other responsibilities of CRA, including detailed Source Data Verification (SDV), are documented by the clinical project manager (CPM) or head of clinical research (HCR)(both are sponsor's representatives). SDVs will be performed and documented during monitoring visits. Monitoring planning, reporting, and visits are pre-defined and documented with pre-made templates per the sponsor's quality management system. Monitoring visits will be performed to cover data from all study participants, and according to QMS and the Standard Operation Procedures. The monitoring shall ensure that all source documentation is precise and document control is exercised in all relevant documentation. The monitoring ensures, that the Adverse events are always reported and appropriate authorities or stakeholders are informed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Description

Inclusion Criteria:

  • Any 18 to 90-year-old patient scheduled for an open-heart operation
  • The ability to understand the study's objective and the risks involved.
  • Informed consent obtained, including the agreement to authorization to use the protected personal patient records according to privacy legislation.

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Myocardial spectrometric recording
Time Frame: During operation
Can the device record myocardial spectrometric data during open-heart surgery
During operation
Measurement correlation
Time Frame: During operation
How the measurements correlate with the occurring events, procedures, and clinical parameters during the operation.
During operation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
