Cardiopulmonary Bypass Surgery

Prior to the implementation of the Medical Device Regulation (MDR), the clinical evaluation of existing devices was conducted by Notified Bodies (NBs) based on clinical data obtained from equivalent devices, and CE certificates were issued for devices exhibiting similar characteristics. Following the transition to the MDR, the European Commission's Guidance Document MEDDEV 2.12/2 highlighted that Notified Bodies, which issued CE certificates under the previous regime, must now organize Post-Marketing Clinical Follow-up (PMCF) studies to verify the performance and safety of the device in accordance with its intended use throughout its lifecycle. Consequently, PMCF studies are being planned to demonstrate that medical devices previously marked with the CE mark under the old regulations are used safely for patients throughout their lifecycle. Primary Objective To demonstrate the performance of the Bıçakcılar Vent Catheter in patients for whom its use is planned, in accordance with the device's intended purpose as outlined in the user manual, taking into account the following aspects: bleeding, trauma, passage manipulation, insertion and removal, compliance with the intended use, occlusion, retention of debris, effective use, and maintenance of its form

Consequently, PMCF studies are being planned to demonstrate that medical devices previously granted CE marking under the old practices can be used safely by patients throughout their lifecycle.

This study aims to evaluate the diagnostic performance of the cardiovascular surgeon's visual estimation of LV function before decannulation following cardiopulmonary bypass, using TEE results as the reference standard.
