VIVO is intended for acquisition, analysis, display and storage of cardiac electrophysiological data and maps for analysis by a physician. VIVO is intended to be used as a pre-procedure planning tool for patients with structurally normal hearts undergoing ablation treatment for idiopathic ventricular arrhythmias.

The VIVO system is a noninvasive pre-procedure planning tool that provides a 3D mapping of the heart to aid in identifying the origin of cardiac arrhythmias prior to electrophysiology procedures. VIVO requires acquisition of MRI or CT images combined with standard ECG recordings and electrode placement. Electrocardiographic potentials are measured from the torso using standard 12 lead electrocardiogram (ECG) electrodes placed on the surface of the body. A DICOM image (CT or MR scan) of the thorax and heart is acquired and then segmented to provide a patient specific, three-dimensional (3D) anatomy of the endocardial and epicardial surfaces of the heart. A 3D photograph of the patient's chest with the precise ECG lead locations and positioning patches that were used to acquire the ECG is merged with the torso and heart model to determine the spatial relationship between them. From these data, the system uses a mathematical algorithm to assimilate the geometrical information and transform the measured body surface signals into epicardial signals by solving the cardiac inverse problem. VIVO software creates, displays, and stores a cardiac activation map that displays the site of earliest activation of ventricular arrhythmias. The VIVO system includes an off the shelf laptop computer and a handheld 3D camera. The preloaded software takes data from previously acquired cardiac and thoracic images, standard 12-lead ECG recording made during an arrhythmia and 3D picture of the ECG leads and positioning patches. This information, obtained prior to the procedure, can be used during pre-procedure planning by a qualified physician.

The VIVO system is a noninvasive pre-procedure planning tool that provides a 3D mapping of the heart to aid in the identification of the general location of the origin of focal ventricular arrhythmias prior to electrophysiology procedures. VIVO requires acquisition of MRI or CT images and standard ECG recordings and lead (electrode) placement. Electrocardiographic potentials are measured from the torso using standard 12 lead electrocardiogram (ECG) sensors placed on the surface of the body. A DICOM image (CT or MR scan) of the thorax and heart is acquired and then segmented to provide a detailed, three-dimensional (3D) anatomy of the endocardial and epicardial surface of the heart. A 3D photograph of the patient's chest with the precise ECG lead positions used to acquire the 12 lead ECG is merged with the torso and heart model to determine the spatial relationship between the electrodes and the heart. From these data, the system uses a mathematical algorithm to use the geometrical information to transform the measured body surface potentials into myocardial potentials via solving the cardiac inverse problem. The VIVO system uses an off the shelf laptop computer and a handheld 3D camera. The VIVO software creates, displays, and stores a cardiac model that displays the site of earliest activation of ventricular arrhythmias. VIVO software is comprised of two software applications, VIVO Anatomy and VIVO Analysis. VIVO Anatomy merges the imported cardiac MR/CT image data with a model to create a heart and torso model representative of a patient's specific anatomy. The MR/CT image data must be imported via a DVD containing the images in DICOM format (Note: VIVO does not have a web interface). The DICOM image is then overlayed on top of one of a number of preloaded anatomical models to fine tune the preloaded model. The model that best matches the patient's anatomical profile is chosen. Specific cardiac structures and tissues are identified by the User within the images to better match the patient anatomy. An outline of the chambers and tissue walls is automatically created by VIVO which is then finetuned by the User for a precise match to the patient's anatomy. VIVO Analysis combines the heart and torso model generated from VIVO Anatomy with ECG data, and a 3D photograph of the ECG lead placement to identify the location of the arrhythmia foci. After ECG leads are placed on the patient, a 3D photograph of the patient's chest is captured to accurately record lead locations. Arrhythmic ECG signals are recorded from these electrodes and imported into the VIVO software. This data is combined and a mathematical algorithm is used create a 3D rendering of the patient's heart with superimposed color coding to indicate the area of earliest activation.
