Summary of Differences in Predicate Device: 6 (a)
Both V3D-Cardiac and the predicate device operate on DICOM images derived from CT scanner.
The V3D-Cardiac provides initial coronary artery tree segmentation automatically. After that. user allows selecting vessel segment by single mouse click at the distal end of the vessel segment. The selection of vessel triggers the final vessel segmentation. The initial artery tree segmentation results intends for vessel anatomy reference only rather than accurate vessel investigation. The predicate device does not provide automatically coronary artery tree segmentation. It provides GUI for semi-automatic extraction of coronary vessels.
2
Both the predicate device and V3D-Cardiac provide semi-automatic tools for left ventricle volume region extraction. The predicate device allows only for end diastolic and end systolic phases for volume analysis. The V3D-Cardiac allows volume measurement for all loaded phases.
6 (b) Discussion of Similarities and Differences:
The Viatronix V3D-Cardiac module utilizes the similar technological characteristics as the predicate device. Both devices are software products that augment an existing 2D/3D DICOM visualization system and are used for post-processing cardiac CT angiography studies.
Both devices permit the physician to segment coronary artery structure. Both devices allow the physician to analysis the coronary artery, cardiac chambers, cardiac valves, and myocardium via multi-planar reformatted images. Both devices also provide planar reformatted images along the vessel. The V3D-Cardiac allows color coded the left ventricle region in 2D views for verifying the segmentation accuracy. The predicate device displays contour around ventricle region for the same purpose. The ejection fraction are the essential indicator in both devices for estimating risk of poorer left ventricle function.
The V3D-Cardiac extracts vessel based on centerline of the contrast enhanced vessel lumen. The predicate device extracts vessel based on the human interaction via the "easy growing" tool. The vessel measurements are similar between both devices.
In summary, both devices are similar in design, utility, and presentation. They allow the physician to analyze the coronary artery, cardiac chambers, valves, and myocardium via reformatted 2D and 3D views. They allow physician selecting coronary artery, qualitative judge artery shape, and quantify the artery size. Both devices allow physician to measure left ventricle ejection fraction as essential indicator of risk of poorer left ventricle function.
- Discussion of Non-Clinical Tests Performed for Determination of Substantial: Equivalence are as follows:
Scanned images datasets of actual patients were selected retrospectively and used as input for testing of software functionalities in accordance with a test procedure document CAR0040 in Exhibit # 5. The V3D-Cardiac software module provided interactive orthogonal and multiplanar reformatted 2D and 3D images from DICOM images to detect and evaluate the abnormalities of heart. The area, diameter, and percentage of stenosis measurement features provided in the software were used to evaluate and quantify any abnormality of coronary arteries. The ejection fraction measurement features in the software were used to evaluate and quantify the risk of function of left ventricle.
The V3D-Cardiac module has been developed in a manner consistent with accepted standards for software development, including both unit and system integration testing protocols. The product has shown itself of reliable, easy to use and capable of evaluating DICOM 3.0 compliant scanned CT images of contrast enhanced human heart. Internal validation for vessel measurements had
3
been implemented on selected actual patient studies. The internal validation compared the measurement created from V3D-Cardiac against to that from V3D-Vascular, revision 2.0, 510k #K033361. (The V3D-Vascular is a module to assist physician reviewing and investigating vascular disease based on CT and MR angiography DICOM images).
We conclude from these tests that V3D-Cardiac module is substantially equivalent to the predicate devices in its ability to evaluate coronary arteries, left ventricle, myocardium, and other parts of human heart.
8. Discussion of Clinical Tests\Evaluations Performed:
Tests and validations on actual patient data were performed per established protocol. The selected patient DICOM images were loaded into the predicate devices. Evaluated coronary arteries results and ejection fraction of left ventricle using the predicate device were recorded. Same image series were loaded into the Viatronix V3D-Cardiac application and the results of evaluation and quantification of coronary arteries and ejection fraction for left ventricle were recorded.
Evaluation results of both predicate device and V3D-Cardiac were same and no significant differences were detected in the results of evaluation.
9. . Conclusions:
The Viatronix V3D-Cardiac has the same intended use and similar technological characteristics as the GE Medical System CardIQ Xpress (FDA 510(k) #K041267, #K013422). Moreover, tests and validations using patient's heart images and non-clinical tests performed demonstrated that the Viatronix V3D-Cardiac application is substantially equivalent to the predicate devices in its ability to review, analyze, measure and evaluate CT scan images of human heart to facilitate analysis and evaluation of abnormality or malformation in vessels by a trained physician. The Viatronix V3D-Cardiac application does not raise any new issues of safety or effectiveness.
