Intended Use
The SQuEEZ Software is an image analysis software application for cardiac Computer Tomography (CT) studies to assist cardiologists and radiologists in assessing function when producing a cardiac evaluation. The software calculates a Stretch Quantifier for Endocardial Engraved Zones (SQuEEZ) value to highlight and color code the wall motions of the heart. Tools are provided to display regional motion properties of the heart.
Device Description
Cardiowise SQuEEZ Software is a post processing image analysis software application for cardiac Computer Tomography (CT) studies to assist cardiologists and radiologists in assessing left ventricle function when producing a cardiac evaluation. SQuEEZ Software enables a quantitative evaluation of the regional myocardial strain using the data from an ultra-high-resolution cardiac CT scan that requires an acquisition time of as short as a single heartbeat. This is done by calculating a Stretch Quantifier for Endocardial Engraved Zones (SQuEEZ) value to highlight and color code the wall motions of the heart. The resulting analysis is graphically presented in threedimensional color contour maps or regional graphical representations that indicate the level of strain the left ventricle experiences during the cardiac cycle.
More Information

No
The summary describes image analysis software that calculates a specific value (SQuEEZ) based on CT data to assess cardiac function. It mentions image processing and quantitative evaluation but does not use terms like AI, ML, deep learning, neural networks, or describe any training or testing of models, which are typical indicators of AI/ML use in medical devices. The performance studies focus on comparisons to existing methods and software testing, not on validating an AI/ML model.

No
The device is an image analysis software used to assist in assessing function, not to treat a condition.

Yes

The software assists cardiologists and radiologists in assessing heart function by calculating a SQuEEZ value and displaying regional motion properties, which are used to evaluate and understand the state of the heart.

Yes

The device is described as a "post processing image analysis software application" that operates on existing cardiac CT studies. It does not mention any hardware components being part of the device itself.

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 SQuEEZ Software analyzes medical images (cardiac CT scans) to assess heart function. It does not analyze biological samples.
  • Intended Use: The intended use is to assist cardiologists and radiologists in assessing function based on image analysis, not on the results of a test performed on a biological sample.

Therefore, the SQuEEZ Software falls under the category of medical image analysis software, not in vitro diagnostics.

7. Device Description

Cardiowise SQuEEZ Software is a post processing image analysis software application for cardiac Computer Tomography (CT) studies to assist cardiologists and radiologists in assessing left ventricle function when producing a cardiac evaluation. SQuEEZ Software enables a quantitative evaluation of the regional myocardial strain using the data from an ultra-high-resolution cardiac CT scan that requires an acquisition time of as short as a single heartbeat. This is done by calculating a Stretch Quantifier for Endocardial Engraved Zones (SQuEEZ) value to highlight and color code the wall motions of the heart. The resulting analysis is graphically presented in threedimensional color contour maps or regional graphical representations that indicate the level of strain the left ventricle experiences during the cardiac cycle.

8. Intended Use/Indications for Use

The SQuEEZ Software is an image analysis software application for cardiac Computer Tomography (CT) studies to assist cardiologists and radiologists in assessing function when producing a cardiac evaluation. The software calculates a Stretch Quantifier for Endocardial Engraved Zones (SQuEEZ) value to highlight and color code the wall motions of the heart. Tools are provided to display regional motion properties of the heart.

9. Comparison of Technological Characteristics with Predicate ·

SQuEEZ Software is substantially equivalent to the predicate device based on the information summarized here:

The subject device has the same intended use as the predicate device cleared in K112531, i.e. software application for post-processing analysis of radiological images to assist in the assessment of the regional function of the heart muscle (myocardium).

The subject device and the device cleared in K112531 both use cardiac CT studies as inout for post-processing. The device cleared in K112531 achieves its intended use by evaluating heart tissue density as an indicator of wall thickening. Transmural wall thickening happens during the ventricular relaxation-contraction process, thus indirectly representing heart wall motions. The predicate device includes tools (segmentation, color-coding, polar maps) to visualize hypo/hyperdense areas of the myocardium. The subject device creates an endocardial mesh to directly track the left ventricle movements through the same ventricular relaxation-contraction process. Form the endocardial mesh, the subject device derives a calculated value, SQuEEZ, representing local motion of the endocardial surface. The subject device includes similar visualization tools for its SQuEEZ values as the predicate device (i.e. segmentation, color-coding, polar maps).

Based on the testing performed, including software verification and validation, digital

phantom study, and animal performance testing, it can be concluded that the subject device does not raise new issues of safety or effectiveness compared to the predicate device. The similar indications for use, technological characteristics, and performance characteristics for the proposed SQuEEZ Software are assessed to be substantially equivalent to the predicate device.

10. Performance Data

The following tests were performed to demonstrate safety based on current industry standards:

  • . Software testing per IEC 62304
  • Non-clinical performance testing including: .
    • o Digital phantom study
    • o Comparison to tagged MRI (magnetic resonance imaging) in acutely infarcted dogs for noninvasive regional myocardial function analysis

The results of these tests indicate that SQuEEZ Software is substantially equivalent to the predicate device.

Additionally, a peer-reviewed publication describing a study of SQuEEZ values in human subjects with normal left ventricle function was provided to support a determination of substantial equivalence for the subject device.

11. Conclusion

Based on the testing performed, including software testing, digital phantom study, and non-clinical performance testing in animals, it can be concluded that the subject device does not raise new issues of safety or effectiveness compared to the predicate device. The similar indications for use, technological characteristics, and performance characteristics for the proposed SQuEEZ Software are assessed to be substantially equivalent to the predicate device.
