The accuracy of two algorithms of artificial intelligence based on neural networks and the CaRDIA-X algorithm in the identification of electronic implantable cardiac devices by chest x-rays.

Abstract

Objectives : In this study, we aim to describe the diagnostic accuracy of two applications neural networks-based system and a visual algorithm performed by different evaluators to identify the manufacturer of electronic implantable cardiac devices by chest x-rays. Background : cardiac rhythm devices frequently require interrogation, and they have different software depending on the manufacturer. Currently, there are a visual algorithm and two applications based on artificial intelligence for the identification of the manufacturer from chest radiographs. Methods : Retrospective trial between January 2010 and December 2021 at a single institution. Chest radiographs were obtained from patients with cardiac devices; they were cropped and resized to 224 by 224 pixels. Then, they were analyzed using the applications Pacemaker ID with a cell phone, Pacemaker ID web and PPMnn web, and the visual algorithm CaRDIA-X performed by evaluators at different levels of training. Results : 400 radiographic images with cardiac devices were collected comprising 4 manufacturers and 40 different models. The agreement for Pacemaker ID with a cell phone was 90.6% ( p <0.001), for Pacemaker ID web was 81.2% ( p < 0.001); and for PPMnn web was 82% ( p < 0.001). The agreement from the CaRDIA-X algorithm performed by 4 evaluators ranged from 73.8% to 97.7% ( p < 0.001). Conclusions : The use of applications based on neural networks offers a good agreement in the identification of the manufacturer and is a tool for clinical use. In our paper, the visual algorithm has a better agreement in identifying the manufacturer and it doesn’t require much training.
