## PREDICATE DEVICE(S) [807.92(a)(3)]

Primary Predicate Device: Volta Medical VX1 (K201298)

Secondary Predicate Device: Medtronic. Inc. CardioInsight® Cardiac Mapping System (K181918)

### DEVICE DESCRIPTION [807.92(a)(4)]

The Vektor Computational ECG Mapping System (vMap™) is a non-invasive software-driven tool for beat-by-beat, multi-chamber, two-dimensional ("2D") and three-dimensional ("3D") analysis and mapping of the heart. vMap" analyzes standard, 12-lead electrocardiographic signals acquired non-invasively from the body surface. vMap™ uses this data to provide various 2D cardiac information and interactive 3D color maps, including cardiac electrical features for analysis by a physician. vMap™ can be used in the clinical environment, such as the electrophysiology ("EP") lab, and in a hospital environment.

The vMap™ System consists of three key components:

- 1. The vMap™ Software, which drives vMap™ and its core analysis functionalities;
- 2. The vMap™ Hardware, the computer workstation which facilitates the use of the vMap™ Software; and
- 3. The vMap™ Disposables, which includes a "Mapping Key" that serves as a license mechanism for the software. Commercial off-the-shelf components such as a USB flash drive and a set of FDA-cleared ECG leads are provided for the physician's convenience.

The electrocardiogram (ECG) signals are displayed and used in proprietary algorithms to transform the measured body surface signals into cardiac signals. vMap™ provides information directly to the physician to help assess patients exhibiting abnormal heart rhythmias). vMap" provides this information by analyzing electrocardiographic information with reference to an arrhythmia-specific cardiac voltage library.

### INDICATIONS FOR USE [807.92(a)(5)]

The Vektor Computational ECG Mapping System (vMap") is intended for the analysis, display, and storage of cardiac electrophysiological data and maps for analysis by a physician.

### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES [807.92(a)(6)]

The proposed device and the predicate devices have intended use and similar Indications for Use. All devices are non-invasive cardiac mapping systems for use by licensed physicians on patients undergoing electrophysiology ("EP") procedures. vMap™, VX1, and CardioInsight® all perform analysis, display, and storage of EP data and maps for analysis by a physician.

The proposed and predicate devices share key technological similarities. In order to process the device signal input and provide output, all devices analyze cardiac electrogram data in order to generate electrical activity "maps" indicative of cardiac electrical activity within the heart anatomy for physician analysis. In consideration of the specific analysis methodology, vMap™

{5}------------------------------------------------

and CardioInsight utilize electrical activity information gathered from surface-lead inputs to estimate the origins of the measured electrical activity. In this analysis, both devices consider the patient's cardiac anatomy to arrive at the mapping result. Further, vMap™ and VX1 also leverage analytical parameters from externally developed models as part of the analysis to relate the input source signals to the final geometric output. There are a few differences between the proposed device and the predicate devices which relate primarily to input signals, mathematical approach, and output map formats, which do not raise different questions of safety or effectiveness, as was further confirmed through the results of bench, usability, and clinical performance testing.

Table 1 presents a tabular comparison of technological characteristics between the proposed device and predicate devices.

Of 75 episodes, which met the criteria for inclusion in this analysis, (premature ventricular complex (PVC) and ventricular tachycardia (VT) arrhythmias in cases with structurally normal hearts and less than 10% scar), vMap correctly identified chamber/region of the clinical arrhythmia ("CAT") location as determined by ground truth in 74 episodes, representing an accuracy of 98.7% (96.0 - 100%).

In addition, both key secondary endpoints were achieved, as follows:

- 1. Of 255 total episodes, vMap™ correctly identified the chamber/region of the CAT location as determined by ground truth (Atria: left atrial free wall, septum, or right atrial free wall; Ventricles: left ventricular free wall, septum, or right ventricular free wall) with an accuracy of 96.9% (95.1% - 98.7%) across all nine arrhythmia subtypes supported by vMap"".
- 2. Of 255 total episodes, vMap" correctly identified the segment or neighboring segment of the CAT location as determined by ground truth with an accuracy of 97.3% (95.2% -99.3%) across all nine arrhythmia subtypes supported by vMap

### CONCLUSIONS [807.92(b)(3)]

The proposed device and the predicate devices have intended use and similar Indications for Use. Furthermore, the proposed and predicate devices share key technological similarities. Demonstrated by the results of bench, usability, and clinical testing, the design of which were highly similar to that of the predicate devices, any technological differences presented with the proposed device do not raise different questions of safety or effectiveness, and the proposed device is as safe and as effective as the predicate devices for the same intended use.

#### SUMMARY

The predicate device's Indications for Use is substantially equivalent to the proposed Indications for Use for vMap". Any differences in the technological characteristics between the devices do not raise different questions of safety or effectiveness.
