The summary describes model-based segmentation and detection algorithms, but does not explicitly mention or imply the use of AI or ML. The performance studies focus on verification and validation against design specifications and user needs, not on the performance metrics typically associated with AI/ML models (e.g., AUC, sensitivity, specificity).
No
The device is a non-invasive post-processing application for pre-operational planning of Transcatheter Aortic Valve Replacement (TAVR) procedures. It provides assessment and measurements of heart structures for device sizing and C-arm angle selection, but it does not directly treat or diagnose a disease. It aids in planning, but the actual therapeutic intervention (TAVR) is performed by an interventional team.
Yes
The device aids in pre-operational planning for transcatheter aortic valve replacement procedures by providing assessment and measurements of relevant heart structures for TAVI-device sizing. While it doesn't make a diagnosis, it provides critical information that directly impacts the diagnostic process of patient eligibility and device selection, thus functioning as a diagnostic aid.
Yes
The device is described as a "non-invasive post-processing application" and "application" throughout the description, focusing on visualization, assessment, and quantification of medical images. The validation activities mention installation on "nominal systems" or "a laptop which meets the HW requirements," implying it is software running on general-purpose hardware, not a dedicated hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The CT TAVI Planning application is a software application that processes medical images (CT scans) of the human heart. It provides visualization, assessment, and quantitative measurements of anatomical structures.
- Lack of Biological Sample Analysis: The device does not analyze any biological samples taken from the patient. Its input is medical imaging data.
Therefore, while it is a medical device used in the planning of a medical procedure, it does not fit the definition of an In Vitro Diagnostic.

Intended Use / Indications for Use
The CT TAVI Planning application is intended to be used for patients with aortic valvular disease, severe symptomatic aortic stenosis or tricuspid aortic valve. The body for this application is the human heart, specifically the ascending aorta, aortic root, coronary ostia and left ventricle in order to assess the aortic valve in pre-operational planning of transcatheter aortic valve replacement procedures.
CT TAVI Planning is a non-invasive post-processing application providing 3D model-based segmentation of the aortic valve and aortic arch. The CT TAVI Planning application provides assessment and measurements of relevant heart structures for TAVI-device sizing, and allows the user to select a starting angle for C-arm position from the possible optimal positions from the CT TAVI and select a C-arm angle the user feels is appropriate to use in the catheterization laboratory by the Interventional team performing the procedure (to be used during the procedure itself).
The physician retains the ultimate responsibility for making the determination of patient eligibility or which device is implanted based on their standard practices and additional imaging modalities such as echocardiography.

Description of the test set, sample size, data source, and annotation protocol
Verification was conducted to provide objective evidence that the application met its design specifications. This was done by testing the function and implementation of the application as well as risk management file. The details of the testing including test plans and reports can be found in [TAVI-008] -Verification of the 510(k). The verification plan for the TAVI Application (TAVI-007) outlines the verification activities conducted to verify the function of the application and product's stability. Testing included full functionality of TAVI application and risk management file (RMF) related to defined requirements. The requirements for TAVI planning are traced to the clinical DRS and detailed test scenarios were written and accordingly the verification was conducted [TAVI-0051. TAVI verification included sanity tests which gave an overview of the application maturity for each build, critical tests which included tests of the main features and workflow and RMF tests which in general check calculations, measurements, patient details and information and other scenarios which might lead to misdiagnosis. Full functionality test included all TAVI functionality cases and covered all of the detailed requirements which provided us with assurance that the tested features work as required. Verification also covered the defect fixes of TAVI.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The TAVI validation activities, as documented in the TAVI Validation Plan (TAVI-009), were performed in the following two ways to provide objective evidence that the TAVI Software Application meets the intended use and defined customer needs as documented in the Customer Requirement Specification (CRS) (ISP-600-P1,2-0002-01 ):
- Internal validation in a non-hospital environment by clinical experts. Clinical experts can be non-Philips employees that can simulate the work of a typical clinical user as long as they did not participate in the development process and verification process. Validation will be done in Philips facilities using nominal systems or outside Philips on a laptop which meets the HW requirements (evidence in ISP-600-P5-0109-01, Using Portal Demo laptops for IntelliSpace Portal validation; and clinical expert report as part of the Verification Report ISP-600-P5-0093-01.
- External validation at beta sites. System is installed in a hospital environment and used by the local medical staff (radiologists and/or cardiologists).
The results of the two validation activities found in the Validation Report for Transcatheter Aortic Valve Implantation (TAVI-0010) confirms that the TAVI software application meets user needs and intended uses.

The application supports contrast-enhanced. prospectively ECG-gated axial or retrospectivelygated helical CT images as well as un-gated helical scans.
The application provides visualization and measurement tools for qualitative and quantitative visualization and assessment of the input data.
It provides tools to determine the size and shape of the aortic root anatomy, ascending aorta and left ventricular outflow tract.
