Spectroscopic Assessment of Intramyocardial Oxygen Saturation Feasibility During Open-heart Surgery

Study Overview
=================
Brief Summary
-----------------
This traditional feasibility study aims to capture preliminary safety and effectiveness information on a near-final Investigational Device design to adequately plan the forthcoming pivotal study.

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.
