Intended Use

Vitrea® Coronary Artery Analysis (CT Cardiac Analysis) is intended for investigating coronary obstructive disease by providing a non-invasive survey of a patient's coronary arteries. Clinicians can select any coronary artery to view the following anatomical references: the highlighted vessel in 3D, two rotatable curved MPR vessel views displayed at 90 degree angles to each other, and cross sections of the vessel. The clinician can semi automatically determine contrasted lumen boundaries, stenosis measurements, and maximum and minimum lumen diameters. In addition, clinicians can edit lumen boundaries and examine Hounsfield unit statistics.

Device Story

Device processes cardiac CTA images from multislice CT scanners (4-slice and above). Core function involves curved multiplanar reformatting (MPR) to visualize coronary arteries. Software performs automatic heart segmentation, zero-click coronary vessel tree segmentation, and labeling of main coronary arteries. New 'Multi-Vessel' preset automatically probes up to 17 additional vessels in coronary trees without labeling. Clinicians use the system to view vessels in 3D, curved MPR, and cross-sections; perform semi-automated lumen boundary detection, stenosis measurements, and plaque burden analysis (SUREPlaque); and edit results. Used in clinical settings by physicians to assess coronary anatomy and obstructive disease. Output assists in clinical decision-making by providing quantitative measurements and anatomical visualizations of coronary vessels.

### DEVICE FUNCTIONS

This submission is for the addition of a new feature, the Witrea CT Cardiac Analysis application. The application. The application was cleared as "CT Coronary Analysis" in K052632 (Vitrea2 v3.8 Medical Image Processing Software).

The previously cleared Vitea CT Cardiac Analysis option (cleared in the predicate submission K052632 under the name "CT Coronary Analysis") provides a variety of tools and vith clinical CT images of the coronary arteries, heart, and surrounding tisse. The software supports CTA studies acquired by 4-slice and above multislice CT scanners, and includes the following features:

- · Automatic segmentation of the heart from the rest of the anatomy
- · Zero-click coronary vessel tree segmentation and automatic labeling of the three main coronary arteries
- · Selection of any coronary artery for viewing with the Vessel Probe tool with easy centerline review and editing
- · Full Vessel Probe capabilities for coronary arteries including the Lesion Tool, Vessel Walk, and Cath View

· A flythrough preset configured for flying through the coronary vessels (Global Illumination Rendering not available in the flythrough view)

- Unique Heart Mode to automatically orient oblique MPR views to show one short-axis view and two long-axis views
- · Key findings classification during reading of the study for semi-automated structured report generation
- · Measurement of plaque burden between the lumen and the outer wall with the SUREPlaque tool
- · Display of a Transluminal Attenuation Gradient for probed vessels.

This submission adds the new Multi-Vessel preset feature. Whereas the offered initial automated probing and labeling of the three main coronary arteries, the new feature adds an additional initial automated probing (without labeling) of up to seventeen additional vessels in the vessel trees associated with the main coronary arterior tree, the left circumflex artery (LCX) tree, and the right coronary artery (RCA) tree. The tree structure allows edits to the trunk to be reflected on all the branch vessels. In both the subject and the predicate devices, the user has the ability to manually probe an unlimited number of additional vessels. The capability of either manually or automatically "probing" vessels was present in the predicate software.

#### SCIENTIFIC CONCEPTS THAT FORM THE BASIS FOR THE DEVICE

The scientific concept underlying the software is the image reconstruction method of curved multiplanar reformatting (MPR), commonly used for the visualization of complex three-dimensional structures, including vessels and treelike vessel structures.

#### SIGNIFICANT PHYSICAL AND PERFORMANCE CHARACTERISTICS OF THE DEVICE

Internal software verification and validation test cardiac CTA images to ensure that the Vitrea CT Cardiac Analysis software functions remained consistent with the software requirements, integration of the Multi-Vessel Probe feature into the software was successful, and the existing functionality of the Vitrea software platform was not degraded. The software achieved all product release criteria.

## Intended Use/Indications for Use

Vitrea® Coronary Artery Analysis) is intended for investigating coronary obstructive disease by providing a noninvasive survey of a patient's coronary arteries.

Clinicians can select any coronary artery to view the following anatomical references: the highlighted vessel in 3D, two rotatable curved MPR vessel views displayed at 90 degree angles to each other, and cross sections of the clinician can semi automatically determine contrasted lumen boundaries, stenosis measurements, and maximum lumen diameters. In addition, clinicians can edit lumen boundaries and examine Hounsfield unit statistics.

## Indications for Use Comparison

The device has a different IFU statement from the predicate. There are two differences:

· The predicate device bundled multiple software applications, including Cardian Functional Analysis, CT Colonography, VScore, and others. This submission is intended to modify only the Coronary Artery Analysis applications contained in the predicate software are not under review. The predicate IFU statement describing other applications have therefore been removed to reflect that only one application is under review. This change to the IFU is a purely administrative change that does not affect the device's technology or intended use or create a new intended use.

### 21 CFR 807.92(a)(5)

21 CFR 807.92(a)(5)

{5}------------------------------------------------

- In the predicate device, the relevant application was called "Coronary Artery Analysis." The subject device renames the application to "Vitrea CT Cardiac Analysis." This name change is intended to better describe the software function and more accurately specify that the software application is for analyzing cardiac CT images. The change does not affect the intended use of the software or create a new intended use.

# Technological Comparison

## 21 CFR 807.92(a)(6)

The device has different technological characteristics from the predicate device.

This submission is for the addition of a new feature, the Mitrea CT Cardiac Analysis software application (this application was cleared as part of the predicate device). After a cardiac CTA study was loaded into the predicate device offered initial automatic probing and labeling of the three main coronary arteries. The new Multi-Vessel preset being added in the subject device expands the software's capability to include initial automatic probing (without labeling) of up to 17 additional vessels in the vessel trees associated with the main coronary arterior tree, the left circumflex artery (LCX) tree, and the right coronary artery (RCA) tree.

Once a vessel has been "probed" (whether manually by the software after loading a study), the user can select the vessel, highlight it, view it in curved reformats or cross-sectional view, and view its centerline and contours. The ability to probe vessels either manually or automatically was present in the predicate device. The user has the ability to manually probe an unlimited number of additional vessels after initial automatic probing. The user has the ability to manually edit any automatic results.

# Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)

Internal software verification and validation were completed to ensure that the CT Cardiac Analysis software functions remained consistent with the software requirements, the integration of the software was successful, and that the software did not degrade the existing functionality of the Vitrea AV software achieved all product release criteria.

Validation was performed by producing, and executing cardiac CTA test cases to ensure that features conformed to all new and previously defined specifications and to ensure that any risks were properly mitigated. The software provides the mapping between requirements, designs, risks, test cases, and final test run results.

The software was designed, developed, tested, verified, and validated according to written procedures. Testing confirmed that the software functions according to its requirements without impacting functionality of either the CT Cardiac Analysis application or the Vitrea Advanced Visualization (AV) software platform.
