The systems are intended to be installed, used, and operated only in accordance with the safety procedures and operating instructions given in the product user information. Systems are to be operated only by appropriately trained healthcare professionals for the purposes for which they were designed. However, nothing stated in the user information reduces your responsibility for sound clinical judgement and best clinical procedure.

The purpose of this 510(k) Pre-market Notification is to introduce the SVS v2 Contrast software application with the EPIQ and Affiniti Series Diagnostic Ultrasound Systems as part of the VM13.0 program.
SVS v2 Contrast is an automated software feature that assists in the selection of images for analysis with the new Philips license options 2D Auto EF Advanced (Adv) developed by DiA Imaging Analysis (K243235), now part of Philips Ultrasound LLC, and existing Philips license options AutoStrain LV; or 2D Auto LV (both K240850) license application in Adult Echo Transthoracic (TTE) examinations.
As described in 510(k) K240850, this feature automatically classifies each acquired image by view and selects an appropriate set of images for Left ventricle (LV) analysis. The classification is based on a Deep Learning AI inference engine; the selection is a non-AI algorithm that considers the view classification and image depth to select the optimal set of images. The difference in SVS v2 Contrast from the predicate SVS v1 (K240850) is that the algorithm is revised to include the selection of optimal images for analysis when contrast is used in routine TTE exams.
Users can launch existing 2D Auto EF; 2D Auto EF Adv; AutoStrain LV; or 2D Auto LV with the set of images that have been automatically selected without the need to review the acquired images and manually select the views. Users may select 2D Auto EF Adv, to process the selected views by SVS v2 Contrast. SVS v2 Contrast prioritizes the contrast image pair; however, if an appropriate pair of contrast images is not found, then Auto EF Adv may select non-contrast images. The manual approach to select views is still available and the user can override automatically selected images from SVS v2 Contrast.
No hardware changes to the EPIQ or Affiniti Series Diagnostic Ultrasound Systems are required when using SVS v2 Contrast, and existing, cleared Philips TTE transducers.
The SVS v2 Contrast feature is supported by all EPIQ models running software version 13.0 or higher including EPIQ CVx/CVxi, EPIQ Elite Advanced, EPIQ Elite, EPIQ 7, EPIQ 5. The SVS v2 Contrast feature is supported by the Affiniti models running software version VM13.0 or higher, including Affiniti CVx, Affiniti 70, Affiniti 50, and Affiniti 30. The SVS v2 Contrast feature is associated with the cardiac adult indication.
Acceptance Criteria and Study Details for SVS v2 Contrast Software
This document outlines the acceptance criteria and details of the study conducted to demonstrate that the Philips Ultrasound systems (EPIQ and Affiniti Series Diagnostic Ultrasound System) with the SVS v2 Contrast software application meet the established performance benchmarks.
1. Table of Acceptance Criteria and Reported Device Performance
| Criteria | Acceptance Criteria | Reported Device Performance (SVS Selected vs Manually Selected Ground Truth) |
|---|---|---|
| Primary Endpoint: Pearson's correlation coefficient (r) for Biplane EF (Automated Selection vs. Manual Selection) | Lower Confidence Bound for the Pearson's correlation coefficient (r) to be > 0.8. (Informed by published literature (Maret, E. B. (2008)) and previous regulatory submissions (K130779, K232500)). Note: The manual selection here refers to "manual contrast clip selection," which was automatically processed within the Contrast EF application, with the automated EF results serving as ground truth. | N = 46: r = 0.953 (95% CI: 0.917, 0.974), p-value 0.8, meeting the acceptance criteria. |
| Agreement Assessment: Bland-Altman Analysis for Biplane EF (Automated Selection vs. Manual Selection) | Acceptable performance for automatic selection of appropriate clips by SVS software and subsequent output of Contrast Enhanced Biplane EF feature compared to the results of Contrast Enhanced Biplane EF from manually selected contrast clips. (No specific numerical thresholds provided for Bland-Altman, but indicated as demonstrating "acceptable performance" if the primary endpoint is met). | N = 46: Mean Difference ± SD = 0.71 ± 4.36 (95% CI for Mean Difference: -0.58, 2.01). Lower LoA = -7.83 (95% CI: -10.06, -5.60), Upper LoA = 9.26 (95% CI: 7.03, 11.49). Reported as demonstrating acceptable performance. |
| Agreement Assessment: Pearson's correlation coefficient (r) for Biplane EF (Automated Selection vs. Manual Tracing Ground Truth) | No explicit independent acceptance criterion for this comparison; serves as an additional supporting analysis. | N = 46: r = 0.938 (95% CI: 0.890, 0.965), p-value |
§ 892.1550 Ultrasonic pulsed doppler imaging system.
(a)
Identification. An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II.
