Intended Use

CARDIOMATCH® is a diagnostic software program that quantitatively analyzes myocardial perfusion in patients injected with Cardiolite® (Tc Sestamibi) or Thallium following a rest/stress Single Photon Emission Computerized Tomography (SPECT) acquisition protocol.

Device Story

CARDIOMATCH® is a diagnostic software tool for quantitative analysis of myocardial perfusion SPECT images. Input consists of reconstructed stress and rest SPECT images from patients injected with Cardiolite® or Thallium-201. The software automatically determines alignment parameters for images, which are verified by an operator. It then performs size and shape normalization to a template using a 3D image registration method. Normalized images are compared against a normal distribution to identify perfusion defects. Output includes 3D representations of normalized images and a table detailing the number, extent, and location of abnormalities. Used in clinical settings by physicians as an adjunctive tool to aid interpretation of MPS SPECT studies. It does not replace standard visual analysis; physicians integrate quantitative results with clinical history, EKG, and visual tomographic images to make final diagnostic decisions.

Clinical Evidence

Independent validation study conducted at Stanford University on over 50 patients. Results demonstrated that the accuracy of the program is similar to or higher than previous quantitative analysis programs. No specific sensitivity, specificity, or AUC metrics were provided in the summary.

Technological Characteristics

Diagnostic software for SPECT image processing. Features automated alignment and 3D image registration for normalization to a template. Compares normalized images to a normal distribution for defect quantification. Operates as an adjunctive tool for physician interpretation of myocardial perfusion studies.

Indications for Use

Indicated for cardiac diagnostic software analysis of myocardial perfusion in patients injected with Cardiolite® or Thallium-201 following rest/stress SPECT acquisition. Prescription use only.

Regulatory Classification

Identification

An emission computed tomography system is a device intended to detect the location and distribution of gamma ray- and positron-emitting radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. This generic type of device may include signal analysis and display equipment, patient and equipment supports, radionuclide anatomical markers, component parts, and accessories.

Device Identification | Common/Usual Name | Cardiac Stress and Rest SPECT Imaging Processing Software | | --- | --- | | Proprietary Name: | CARDIOMATCH® | ## C. Identification of Predicate Device(s) CARDIOMATCH® is substantially equivalent to the following previously cleared and currently marketed devices: | General Electric | C-Equal™ | K914527 | November 22, 1991 | | --- | --- | --- | --- | | NUC Cardiac | C-Equal | K914296 | November 27, 1991 | ## D. Indications for Use CARDIOMATCH® is a diagnostic software program that quantitatively analyzes myocardial perfusion in patients injected with Cardiolite® (Tc Sestamibi) or Thallium following a rest/stress Single Photon Emission Computerized Tomography (SPECT) acquisition protocol. ## E. Device Description The program automatically determines the alignment parameters for the stress and rest reconstructed MPS SPECT images and, following operator verification of these parameters, performs a size and shape normalization to a template using a published and independently validated 3D image registration method. The normalized images are then compared to a normal distribution and the results of this comparison are used to generate a visual and quantitative representation of the extent and location of perfusion defects. 29 {1} FOCUS MEDICAL S.A. Results are presented in the form of 3D representation of the normalized images including a visualization of the abnormalities as well as a table indicating the number, extent and location of abnormalities. ## F. Marketing history There has been other diagnostic software programs marketed in the past, in particular CEqual™, which perform similar functions to those performed by CARDIOMATCH®. These programs are used to quantitatively analyze the myocardial perfusion of patients injected with Cardiolite® (Tc Sestamibi) or TI²⁰¹, another myocardial perfusion agent. The most widely utilized quantitative programs are the Cedars-Sinai "Bullseye" method, and Emory University and General Electric method embodied in CEqual™. To our knowledge there have been no safety problems with either of these two widely used methods which have been in the marketplace for over the past nine and six years, respectively. ## G. Potential Adverse Effect on Health The intent of the program is to provide the physician with an adjunctive diagnostic tool to aid in the diagnostic interpretation of the patients MPS SPECT studies. It is not meant to replace or eliminate the standard visual analysis of the MPS images. The physician should integrate all of the patient's clinical and diagnostic information, i.e. patient's history, stress and/or rest EKG, quality control images, visual interpretation of the tomographic images, and quantitative results prior to making his final interpretation. This program (as all other diagnostic imaging programs) is not perfect and will be associated with some false positives and false negative results. The physician should be aware of the program's limitations and accuracy when integrating the quantitative results for his final interpretation. Therefore the program has no adverse effect on health since the results represent only a part of the information which the physician will utilize for his final interpretation. The final responsibility for integration of the results and interpretation of the study lies with the physician. ## H. Conclusions The safety of this program has been established through the various stages of software development which included the initial design, coding, debugging, testing and in-house validation. The safety and effectiveness has also been established in an independent validation study on over 50 patients performed at Stanford University. The accuracy results obtained with this program are similar or higher to those obtained with previous quantitative analysis programs. We contend that the method employed for the development and the independent validation of the program (CARDIOMATCH®) have demonstrated its safety and effectiveness. 30 {2} DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 Jean-Luc Boulnois, Ph.D. President Focus Medical SA c/o Interactive Consulting 70 Walnut Street Wellesley, MA 02181 Re: K970970 CardioMatch Dated: March 12, 1997 Received: March 17, 1997 Regulatory class: II 21 CFR 892.1200/Procode: 90 KPS Dear Dr. Boulnois: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act).
