Intended Use

The CorVista® System analyzes sensor-acquired physiological signals of patients presenting with cardiovascular symptoms (such as chest pain, dyspnea, fatigue) to indicate the likelihood of significant coronary artery disease. The analysis is presented for interpretation by healthcare providers in conjunction with their clinical judgment, the patient's signs, symptoms, and clinical history as an aid in diagnosis.

Device Story

CorVista System is a non-invasive, modular diagnostic platform; acquires physiological signals via 7-channel VCG (cardiac electrical) and PPG (hemodynamic) sensors; processes data through a machine-learning detection algorithm to output a likelihood score for significant coronary artery disease (CAD). Used in professional healthcare settings (clinics, hospitals) by clinicians; output displayed on tablet, mobile, or web portal. Assists healthcare providers in clinical decision-making by providing diagnostic aid for symptomatic patients; intended to be used alongside clinical judgment, patient history, and physical signs. Benefits include non-invasive assessment of CAD likelihood, potentially streamlining diagnostic pathways.

Clinical Evidence

Prospective, multicenter, nonrandomized study (N=1,816) of symptomatic patients. Ground truth established via invasive coronary angiography (ICA) or Computed Tomography Angiography (CTA). Performance metrics: 88% sensitivity, 51% specificity, 0.80 AUC-ROC. Repeatability and reproducibility confirmed via IDENTIFY study (multiple signals collected by same/different coordinators).

Technological Characteristics

Modular system: CorVista Base System (hardware/firmware/software) + CAD Add-On Module. Sensors: 7-channel VCG lead set, PPG sensor. Connectivity: Cellular/WiFi to web-based portal. Standards: IEC 60601-1, 60601-1-2, 60601-2-25, 80601-2-61, 60259, 62133, AIM 7351731, ANSI IEEE C63.27, FCC Part 15. Biocompatibility: ISO 10993-1, 10993-5, 10993-10. Algorithm: Machine learning-based detection.

Indications for Use

Indicated for adult patients presenting with cardiovascular symptoms (e.g., chest pain, dyspnea, fatigue) to aid in the diagnosis of significant coronary artery disease (CAD).

Regulatory Classification

Identification

Viz HCM is a cardiovascular machine learning-based notification software intended to be used in parallel to the standard of care to analyze 12-lead ECG recordings from patients 18 years of age or older. It detects signs associated with hypertrophic cardiomyopathy (HCM) and allows the user to view the ECG and analysis results. It is not intended for use on patients with implanted pacemakers, does not replace standard diagnostic methods, and is not intended to rule out HCM or be used in lieu of a full patient evaluation.

Special Controls

In combination with the general controls of the FD&C Act, cardiovascular machine learningbased notification software is subject to the following special controls:

Dear Gabrielle Zaeska:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

#### Device Description

The CorVista® System is a non-invasive medical device system comprised of several hardware and software components that are designed to work together to allow a physician to evaluate the patient for the presence of cardiac disease, or cardiac disease indicators, using a static detection algorithm.

The CorVista System has a modular design, where disease-specific "Add-On Modules" will integrate with a single platform, the CorVista Base System, to realize its intended use. The CorVista Base System is a combination of hardware, firmware, and software components with the functionality to acquire, transmit, store, and analyze data, and to generate a report for display in a secure web-based portal. The architecture of the CorVista Base system allows for integration with indication-specific "Add-Ons" which perform data analysis using a machine learned detection algorithm to indicate the likelihood of specific diseases at point of care. The CAD Add-On indicates the likelihood of significant Coronary Artery Disease (CAD). The analysis is presented for interpretation by healthcare providers in conjunction with their clinical judgment, the patient's signs, symptoms, and clinical history as an aid in diagnosis.

#### Indications for Use

The Cor Vista® System analyzes sensor-acquired physiological signals of patients presenting with cardiovascular symptoms (such as chest pain, dyspnea, fatigue) to indicate the likelihood of significant coronary artery disease. The analysis is presented for interpretation by healthcare providers in conjunction with their clinical judgment, the patient's signs, symptoms, and clinical history as an aid in diagnosis.

### Substantial Equivalence

The CorVista System is substantially equivalent to its predicate device, Viz HCM (DEN230003).

The table below provides a detailed comparison of the CorVista System to the predicate device.
