The OptoMonitor 3 is intended to measure cardiovascular blood pressure, including in heart chambers, coronary vessels and peripheral vessels, during interventional procedures.
Blood pressure measurements provide hemodynamic information, such as fractional flow reserve for the diagnosis and treatment of blood vessels and such as valve gradients during structural heart procedures.
The OptoMonitor 3 with Display Unit Software update to v1.3.0 and Capture Unit when compared to the OptoMonitor 3 cleared under K241418 includes the following changes:
New PhysioVU Software Functionality:
The PhysioVU functionality added to the OptoMonitor 3 provides a feature designed to support the cardiologist PCI workflow by displaying a time-synchronized playback of angiogram and coronary physiological pullback values such as Pd/Pa or dPR. This feature can be utilized on angiography systems compatible with PhysioVU requirements. The validation of PhysioVU's compatibility and overall latency performance was evaluated on three representative angiography systems at 7.5 fps and 15 fps.
dPR Pullback:
A dPR Pullback display optimization has been incorporated to meet the time-synchronization requirements of PhysioVU functionality and is called Pullback 2. Pullback 2 provides an adequate delay between the angiography image and the dPR calculation and can be used as a standalone or a PhysioVU pullback.
New Capture Unit (Hardware):
The Capture Unit component is optional but required for the PhysioVU functionality. The Capture Unit is used to capture angiography images that are sent to the Display Unit. This enables the Display Unit to subsequently replay recordings of these angiograms synchronized with physiological pullback values such as Pd/Pa or dPR.

PERFORMANCE DATA
Software Verification and Validation Testing
Non-clinical performance testing has been performed on the OptoMonitor 3 system and demonstrated compliance with the following International and FDA‐recognized consensus standards in-line with FDA guidance documents: IEC 62304:2006/AMD1:2015 Medical device software – Software life cycle processes.
Software Verification and Validation activities were carried out to confirm proper operation of the device's software. Bench testing was conducted to assess the device's functionality and reliability under typical usage conditions, ensuring it meets all specified performance criteria.
Synchronization performance testing was conducted to provide evidence of accurate temporal registration of the pressure and image signals during clinical use. The intrinsic latency of the OptoMonitor 3 system was characterized by using an artificial heart bench test. Tests in Cathlab were also performed to evaluate the end-to-end latency in real environments (i.e. interfacing with real angiographic system).
