Transcatheter Aortic Valve Implantation (TAVI) or Replacement (TAVR) are procedures for select patients with severe aortic stenosis. TAVI Analysis is a post-processing software package for the Advantage Workstation (AW) and AW Server platforms. It is a planning tool used for sizing, planning and visualization in TAVI/TAVR procedures. TAVI Analysis provides guided workflow and semi-automated tools to help determine aortic annulus size, give guidance for C-arm angulation for deployment of the device, evaluate appropriate access pathways and can communicate directly with the interventional suite.

Intended Use

TAVI Analysis for CT
TAVI Analysis is intended to provide an optimized non-invasive application to analyze vascular anatomy and pathology and aid in determining treatment paths from a set of Computed Tomography (CT) Angiographic images.

TAVI Analysis is a post processing application option for the Advantage Workstation (AW) platform, CT Scanner or PACS workstations, which can be used in the analysis of 2D and 3D CT Angiography images/data derived from DICOM 3.0 compliant CT scans for the purpose of cardiovascular and vascular disease assessment. This software is designed to support the physician in assessment of stenosis analysis, pre/post stent planning and directional vessel tortuosity visualization.

TAVI Analysis automatic visualization tools provide users with the capabilities to facilitate segmentation of bony structures for accurate identification of the vessels. Once vessels are visualized, tools are available for sizing the vessel, analyzing calcified and non-calcified plaque to determine the densities of plaque within a coronary artery, and measure areas of abnormalities within a vessel.

TAVI Analysis for X-Ray
TAVI Analysis is a software post processing option for the Advantage Workstation (AW) Platform, which can be used in the analysis of 3D angiography data. It provides a number of display, measurement and batch filming/archive features and will aid physicians in studying user selected vessels for stenosis analysis, pre/post stent planning, and directional vessel tortuosity visualization.
