- To protect the privacy and security of sensitive information, including electronic protected health information (EPHI), and to protect the integrity of the system itself, the system should be located in a physically secure, access-controlled environment.
- To protect the privacy and security of sensitive information, including electronic protected health information (EPHI), the PC on to which CoroFlow‡ is installed must be configured according to the Installation Instructions in this manual. Failure to configure the PC correctly may result in increased risk for unauthorized release of protected health information. Windows settings include:
- Activation and configuration of restricted user Access
- Activation of Windows Firewall and blocking of network connections
- Activation of Windows Bitlocker drive encryption
- Activation of Windows Secure Boot
- Activation of Windows Anti-Virus scanning and ransomware protection. Ensure CoroFlow‡ is added in the list of trusted applications.
- Activation of Windows update
- Disable unused interfaces
- Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.
- Use of accessories, transducers and cables other than those specified or provided by Coroventis‡ could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.
- Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of CoroFlow‡, including cables specified by Coroventis‡. Otherwise, degradation of the performance of this equipment could result.
Precautions:
- The PC and CoroHub‡ shall not be placed within the patient environment (1.5 m from patient).
- For operation of other devices used in conjunction with CoroFlow‡ consult the IFU for each of these devices for details on indication, handling and safety information.
- It is recommended to ensure local routines for data backup of stored recordings. CoroFlow‡ does not create backup of stored data.
- Always check minimum performance requirement on PC to ensure compatibility with CoroFlow‡.
- It is recommended to install CoroFlow‡ on a PC with backup battery to avoid interruption in case of power failure.
- Always manually review and confirm valid cursor positions and detected heart beats.
- Ensure that Pa and Pd pressure waveforms are aligned in phase and offset after equalization, or indices can be mis-calculated.
- Confirm that the correct Wi-Box is selected by manually matching the Wi-Box ID number with the Wi-Box in the lab.
- Changing parameter settings outside of default values may affect measurement performance, only for research purposes.
- Only to be used by healthcare professionals.
- Using a network location to store data may cause previously unidentified risks if the network malfunctions.
- No modification or tampering with CoroFlow‡ is permitted.
- CoroFlow‡, including accessories and components, shall not be used if it has been subject to damage.

- PPG values may be non-unique and different combinations or focal/diffuse disease may result in the same PPG value.
- Direct connection to a non-secure network, like the internet, may interfere with correct operation and/or result in inappropriate access to patient information. Furthermore, it should be noted that reconfiguring a used network may lead to inability to import patient as well as export examination data, ultimately leading to a risk of loss of patient and examination data. To avoid this problem Coroventis‡ recommends verifying network settings in the system setup after each change. The same caution is relevant regarding connection to DICOM.
- Always confirm valid pressure tracings, marker positions and selected beats.
- Resetting CoroHub‡ will reset PressureWire connections and Zeroing/Equalization parameters.

- Local and/or systemic infection
- Mechanical damage
- Inaccurate readings
- Observe all guidewire movements. Whenever the guidewire is moved or torqued, the tip movement should be examined under fluoroscopy. Never push, withdraw, or torque the guidewire if it meets resistance or without observing corresponding movement of the tip, otherwise vessel/ventricle trauma may occur.
- Torquing or excessive manipulation of the guidewire in a sharp bend, against resistance, or repeated attempts to cross a total vessel occlusion may:
- Cause dissection or perforation of blood vessels
- Cause vessel spasm
- Damage and/or fracture the guidewire
- When introducing the guidewire, flush the catheter and administer anticoagulation as for a standard catheterization procedure or clotting may occur.
- Do not use the guidewire in the ventricles if the patient has a prosthetic mechanical or biological valve. It may result in damage to both the prosthesis and the guidewire, which may cause injury or death.
- Use of the PressureWire™ X Guidewire in conjunction with interventional devices with a short rapid exchange may result in a folded or fractured guidewire.
- High frequency surgical devices must not be used on a patient at the same time as the guidewire.
Precautions:
- The PressureWire™ X Guidewire is a delicate instrument and should be handled carefully.
- Make sure that the transmitter is kept dry to ensure accurate pressure and/or temperature readings. Inaccurate readings may necessitate device replacement.
