The document mentions "analysis procedure" and "heart sound detection algorithm" but does not explicitly state whether these utilize AI or ML. The lack of mention of AI/ML terms, training/test sets, or performance metrics commonly associated with AI/ML models makes it difficult to definitively confirm or deny the presence of such technology.
No
The device is used to assist physicians in the evaluation and analysis of heart sounds, not for direct treatment or therapy.
Yes
The device "will acquire and record the acoustic signals of the heart and analyze these signals" to "identify specific heart sounds that may be present," including "S1, S2, and suspected murmurs," which are diagnostic findings. Although it states it is "not intended as a sole means of diagnosis," it is intended to "provide support to the physician in the evaluation of heart sounds," which is a diagnostic purpose.
No
The device description explicitly states that the complete system is comprised of an electronic stethoscope, a notebook computer, software, a printer, and an isolation transformer, indicating it includes hardware components. The performance studies also mention independent evaluation of hardware components.
Based on the provided information, the Zargis Acoustic Cardioscan (ZAC) is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. The ZAC analyzes acoustic signals of the heart, which are sounds produced by the body, not a sample taken from it (like blood, urine, or tissue).
- The intended use describes analyzing heart sounds. The description focuses on acquiring, recording, and analyzing acoustic signals of the heart to identify sounds like S1, S2, and suspected murmurs. This is a form of physiological monitoring and analysis, not the analysis of a biological sample.
- The device description reinforces this. It describes an electronic stethoscope, computer, software, etc., all components used for capturing and processing sound waves, not for handling and analyzing biological specimens.
Therefore, the ZAC falls under the category of a medical device that analyzes physiological signals, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Zargis Acoustic Cardioscan, (ZAC), is an electronic auscultatory device, intended to provide support to the physician in the evaluation of heart sounds in patients.
The product will acquire and record the acoustic signals of the heart and analyze these signals. The analysis procedure will identify specific heart sounds that may be present. Identified sounds include S1, S2, and suspected murmurs.
The device is indicated for use in a clinical setting, by a physician or by trained personnel who are acting on the orders of a licensed physician. It is not intended as a sole means of diagnosis.
The interpretations of heart sounds offered by the Zargis Acoustic Cardioscan are only significant when used in conjunction with physician over-read as well as consideration of all other relevant patient data.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A comprehensive list of verification and validation testing was performed in accordance with Zargis' Design Control procedures.
The ZAC product consists of hardware and software components. The electronic stethoscope, processing platform, and isolation transformer were independently evaluated as hardware components. The printer and interface cabling were verified at the system level.
Software verification was performed at the module and system level. The integrated ZAC system was further evaluated to verify the graphic user interface software and the ZAC system as an integrated product.
Validation of the ZAC was performed to ensure that the ZAC device consistently fulfills its intended use and the needs of the user. A clinical software validation was performed to insure the performance of the heart sound detection algorithm. In addition, usability validation (i.e., simulated use), reproducibility validation, and software component validation were performed.
