The subject and predicate devices are intended for use with CTA DICOM images to support TAVR planning by measuring aortic root anatomy and vascular access dimensions. The subject device uses deep learning methods to perform some of the segmentation and landmark identification required to initialize measurements, whereas the predicate device uses traditional segmentation and pattern identification algorithms and automatically initializes fewer outputs. The reference device automates some of the measurements using AI/ML. All automatically initialized outputs from the subject device are user reviewable and editable. All algorithms and functionality associated with this feature are imported unchanged from Canon's previously cleared Endovascular Stent Planning Software (cleared as K091498, updated K143079). Regression testing was conducted to validate that the functionality integrated correctly with the rest of the device.

In summary, the main difference between the subject and predicate device is that the subject device adds AI/ML based automatic initialization of aortic root measurements, whereas the predicate device only allowed the user to make these measurements manually. These differences do not raise new questions of safety or effectiveness. The subject device's algorithms have been validated through performance testing, meeting pre-specified acceptance criteria and demonstrating accuracy and reliability.
The new functionality is similar to that in reference device K233209 (uOmnispace.CT, United Imaging), which also makes AI/ML enabled semi-automated measurements of the aortic root.
## VIII. Non-Clinical and/or Clinical Tests, Summary and Conclusions
The device was trained and tuned using diverse retrospective CT data representing a wide range of patient anatomies, acquisition protocols, scanner manufacturers, and disease presentations relevant to TAVR planning. The training set consisted of 218 cases.
The validation dataset for the aortic root measurements included 89 independent TAVR CT planning cases spanning multiple U.S. and international institutions, with diversity in demographics (age, sex), imaging characteristics (scanner vendor, scanner model, slice thickness, kVp), and calcification severity. Scanner representation included Canon, GE, Philips, and Siemens systems).
## Characteristics of the dataset follow:
### Demographic distribution (Gender, Age, Ethnicity)
#### Gender
- Female: 30
- Male: 42
- Unknown: 17
#### Age

# Clinical Subgroups and Confounders
The validation dataset was intentionally designed to include these clinical subgroups and confounders, with subgroup performance analyses performed:
- Sex: Male, Female, Unknown
Age: 50-79 years, $\geq 80$ years, Unknown
- Valve Calcification Severity: None (n=18), Mild/Moderate (n=35), Severe (n=36)
The validation dataset also includes challenging and edge cases related to anatomy and imaging conditions:
- LVOT calcification
Horizontal aorta (high coronal angle)
- Reduced IV contrast
Low kVp imaging (<120 kVp)
# Exclusions
- Cases with severe motion artifacts
Poor contrast or non-diagnostic phases
# Equipment and Protocols for Image Acquisition
# CT Equipment
- Scanners from Canon, Siemens, GE, and Philips were used.
# Imaging Protocol Parameters
- Slice thickness: $\leq 1.0$ mm (subgroups $\leq 0.5$ mm, $>0.5 - 1.0$ mm).
Tube energy: 100-120 kVp.
Cardiac phases: systolic (20–30%) and diastolic (~80%).
# Truthing Process
- Ground truth measurements were determined by two independent, board-certified cardiac CT readers.
- The FDA-cleared predicate device was used to manually generate these measurements.
Each reader was unaware of the other's findings and did not see the automated results.
- For every measurement, the ground truth was established by averaging the values from both readers.
- Agreement between the readers was documented to ensure consistency with the TAVR literature previously published.
Validation truthers were completely independent of training truthers. The validation dataset was retrospective and distinct from any training activities. The device performance was measured by comparing device outputs with ground truth created manually by expert physicians. The overall device performance is summarized in Table 2.

All primary measurements met their pre-specified acceptance criteria except for the LVOT maximum diameter, which demonstrated a slightly lower ICC; however, the associated absolute differences and Bland-Altman limits of agreement were small, within clinically acceptable margins, and not expected to affect annular sizing or overall clinical use.
Comprehensive subgroup analyses across CT scanner vendors, slice thickness, tube energy, reconstruction kernels, calcification severity, patient age, sex, and geographic distribution showed consistent performance. A lower ICC observed in a female-only subgroup was determined to be due to a single case with severe motion artifact and a very narrow measurement range, conditions under which ICC is not a reliable indicator of accuracy; absolute error and Bland-Altman results for the subgroup were consistent with the overall dataset. These isolated deviations were attributed to limitations on the quality of the input image rather than systematic algorithm behavior and do not impact device safety or effectiveness.

The optional aortic leaflet-coloring feature was evaluated separately using a multi-reader Likert-scale quality assessment, with over 93% of cases rated Good or Excellent, exceeding acceptance criteria. Overall, the bench testing demonstrated that the device performs as intended, with measurement accuracy comparable to expert clinical assessment, supporting substantial equivalence to the predicate device.
## Conclusion on Non-Clinical Testing
The non-clinical testing of the CT TAVR Planning Assist demonstrated that the device delivers accurate and reliable measurements for key anatomical parameters relevant to TAVR planning. Performance validation using retrospective CT datasets confirmed strong agreement between the device outputs and clinician-generated ground truth measurements, with high intraclass correlation coefficients (ICC) across all measured parameters. The results indicate minimal bias and narrow confidence intervals, supporting the device's precision and consistency. Collectively, these findings confirm that the device's AI-assisted workflow is robust and suitable for its intended use in pre-procedural planning, meeting the established performance criteria without introducing new questions of safety or effectiveness.
## IX. Substantial Equivalence Analysis Conclusion
The results of the non-clinical and performance validation testing demonstrate that the subject device is as safe and effective as the predicate device for its intended use. The TAVR planning measurements demonstrate robust agreement to clinician-generated ground truth, with no evidence of clinically significant bias or performance variability across subgroups. The aortic leaflet segmentation delivered consistently high visualization quality. These findings support the substantial equivalence of the device to the predicate devices, wot no new questions of safety or effectiveness raised by its introduction. Therefore, the CT TAVR Planning Assist device meets the requirements for market clearance under the 510(k) pathway.
