cvi42 Software Application ("cvi42") is a software as a medical device (SaMD) that is intended for evaluating CT and MR images of the cardiovascular system. Combining digital image processing, visualization, quantification, and reporting tools, cvi42 is designed to support physicians in the evaluation and analysis of cardiovascular imaqing studies. cvi42 uses machine learning techniques to aid in semi-automatic contouring of regions of interest in cardiac MR or CT images. The data used to train these machine learning algorithms were sourced from multiple clinical sites from urban centers and from different countries. When selecting data for training, the importance of model generalization was considered and data was selected such that a good distribution of patient demographics, scanner, and image parameters were represented. The separation into training versus validation datasets is made on the study level to ensure no overlap between the two sets. As such, different scans from the same study were not split between the training and validation datasets. None of the cases used for model validation were used for training the machine learning models. cvi42 has a graphical user interface which allows users to analyze cardiac MR & CT images qualitatively and quantitatively. cvi42 accepts uploaded data files previously acquired by MR or CT scanners or other data collection equipment but does not interface directly with such equipment. Its functionality is independent of the type of vender acquisition equipment. The analysis results are available onscreen and can be saved with the software for future review.

Coronary Analysis: semi-automatic placement of centerline in coronary vessels to visualize the coronary arteries and assess stenosis in non-contrast enhanced CT images. The data used to train these machine learning algorithms were sourced from multiple clinical sites from urban centers and from different countries. When selecting data for training, the importance of model generalization was considered and data was selected such that a good distribution of patient demographics, scanner, and image parameters were represented. The separation into training versus validation datasets is made on the study level to ensure no overlap between the two sets. As such, different scans from the same study were not split between the training and validation datasets. None of the cases used for model validation were used for training the machine learning models. cvi42 Auto software has a graphical user interface which allows users to analyze cardiac images qualitatively and quantitatively for volume/mass, function and signal intensity changes including a reporting function. The device can be integrated into a hospital, private practice environment, or medical research institution and provides clinical diagnosis decision support tools for the cardiovascular MR and CT technique. Additionally, the software is designed to generate 3D view of the heart in CT images for qualitative assessment of the coronary artery. No quantitative assessment can be made from the 3D image. The software does not interface directly with any data collection equipment; instead, the software uploads data files previously generated by such equipment. Its functionality is independent of the type of vendor acquisition equipment. The analysis results are available on-screen and can be saved within the software for future review.

TruPlan enables visualization and measurement of structures of the heart and vessels for pre-procedural planning and sizing for the left atrial appendage closure (LAAC) procedure. To facilitate the above, TruPlan provides general functionality such as: - Segmentation of cardiovascular structures - Visualization and image reconstruction techniques: 2D review, Volume Rendering. MPR - Simulation of TEE views, ICE views, and fluoroscopic rendering - Measurement and annotation tools - Reporting tools

The TruPlan Computed Tomography (CT) Imaging Software application (referred to herein as "TruPlan") is a software as a medical device (SAMD) that helps qualified users with imagebased pre-operative planning of Left Atrial Appendage Closure (LAAC) procedure using CT data. The TruPlan device is designed to support the anatomical assessment of the Left Atrial Appendage (LAA) prior to the LAAC procedure. This includes the assessment of the LAA size, shape, and relationships with adjacent cardiac and extracardiac structures. This assessment helps the physician determine the size of a closure device needed for the LAAC procedure. The TruPlan application is a visualization software and has basic measurement tools. The device is intended to be used as an aid to the existing standard of care. It is not replacing the existing software applications physicians use for planning the Left Atrial Appendage Closure procedure. Pre-existing CT images are uploaded in TruPlan application manually by the end-user. The images can be viewed by the user in the original CT image as well as simulated views. The software displays the views in a modular format as follows: - LAA - Fluoro (fluoroscopy, simulation) - Trans Esophageal Echo (TEE, simulation) - Intra Cardiac Echography (ICE, simulation) - Thrombus - Multiplanar Reconstruction (MPR) Each of these views offer the user visualization and quantification capabilities for pre-procedural planning of the Left Atrial Appendage Closure procedure; none are intended for diagnosis. The quantification tools are based on user-identified regions of interest and are user-modifiable. The device allows users to perform the measurements (all done on MPR viewers) listed in Table 1. Additionally, the device generates a 3D rendering of the heart (including left ventricle, left atrium, and LAA) using machine learning methodology. The 3D rendering is for visualization purposes only. No measurements or annotation can be done using this view. TruPlan also provides reporting functionality to capture screenshots and measurements and to store them as a PDF document. TruPlan is installed as a standalone software onto the user's Windows PC (desktop) or laptop (Windows is the only supported operating system). TruPlan does not operate on a server or cloud.
