No
The document describes image processing and quantitative analysis of PET images but does not mention AI, ML, or related terms. The performance studies compare the new device to a predicate device using traditional statistical methods, not AI/ML validation metrics.
No
The device is a software tool used to quantify myocardial perfusion and coronary flow reserve from PET images to assist physicians in diagnosing coronary artery disease. It does not provide any treatment or therapy.
Yes
The device is described as assisting clinical interpretation of PET perfusion images by quantification of their severity in patients with suspected or known coronary artery disease, which directly supports a diagnostic process.
Yes
The device description explicitly states "HeartSee K171303 is a software tool" and describes its function as importing and processing DICOM images and quantifying data. There is no mention of any accompanying hardware components.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. The description of HeartSee K171303 clearly states that it processes cardiac PET images, which are generated by a medical imaging device (a PET scanner) that interacts with the patient. It does not analyze biological samples like blood, urine, or tissue.
- The intended use is for interpreting medical images. The software assists in the interpretation of PET perfusion images by quantifying data derived from those images. This is a function of medical image analysis, not in vitro testing of biological samples.
Therefore, HeartSee K171303 falls under the category of a medical device that processes imaging data, not an In Vitro Diagnostic device.

Device Description
HeartSee K171303 is a software tool for cardiac positron emission tomography (PET) for determining regional and global absolute rest and stress myocardial perfusion in cc/min/q, Coronary Flow Reserve and the Coronary Flow Capacity (CFC) Map for facilitating the interpretation of PET perfusion images in patients with suspected ot known coronary artery disease. HeartSee K171303 is intended for use by trained professionals, such as nuclear technicians, nuclear medicine or nuclear cardiology physicians, or cardiologists with appropriate training and certification.
HeartSee contains two fundamental components. First, the software imports cardiac PET images in DICOM format from PET scanners with DICOM output. These images are reoriented to cardiac axes to produce standard tomographic and topographic displays of relative uptake. Second, the K171303 software quantifies absolute rest and stress myocardial perfusion per unit tissue (cc/min/g), Coronary Flow Reserve (CFR) as the stress/rest perfusion ratio and the Coronary Flow Capacity combining CFR and stress perfusion, all on a pixel basis for regional and global values. Archiving output data is supported for clinical diagnostics, quality control and research.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
4188 rest and 4188 stress PET perfusion scans were analyzed by K143664 and separately by K171303. Rest and stress perfusion values in cc/min/g and CFR using K171303 were identical within two decimal places to the values using K143664, as were the mean values and their standard deviations. Rest-stress perfusion and CFR using K171303 and 143664 were tightly correlated with R = 1.0 and P

Summary of technological characteristics of your device compared to predicate
device: K171303 and K143664 are software tools using identical standard, industrial computing hardware and applications The code in the software package K171303 is identical to K143664 including determination of quantitative myocardial perfusion in cc/min/g and Coronary Flow Reserve (CFR) and their displays except for the addition of the Coronary Flow Capacity (CFC) map to K171303.
In K171303, Coronary Flow Capacity combines CFR and stress perfusion by plotting their values for each pixel on a clinically defined, objective, color coded plot of combined ranges of values that assigns a color to that pixel for the corresponding range of combined values of CFR and stress perfusion. That color-coded pixel is then back projected into its original coordinate position in the topographic map. All pixels of the LV image are correspondingly color coded for ranges of combined CFR and stress perfusion for each pixel thereby producing a single four quadrant left ventricular map of the combined CFR-stress perfusion ranges. By incorporating all the stress perfusion and CFR data into objectively coded ranges on a pixel basis, the CFC map accounts for global and regional heterogeneity, objectively simplifies complex data for optimal clinical interpretation and associates with major adverse coronary events (MACE) and decreased death and myocardial infarction after revascularization better than CFR or stress flow alone in K143664.
Summary of performance data:
In 4188 rest and 4188 stress PET perfusion scans were analyzed by K143664 and separately by K171303. Rest and stress perfusion values in cc/min/g and CFR using K171303 were identical within two decimal places to the values using K143664, as were the mean values and their standard deviations. Rest-stress perfusion and CFR using K171303 and 143664 were tightly correlated with R = 1.0 and P
