Overview

Transcatheter Aortic Valve Replacement/Implantation (TAVR/TAVI) demands meticulous, detailed planning to be successful. You need detailed information such as confirmation of valve stenosis, viable access approach, distances to ostia, elliptical aortic root dimension, identification of the valve plane, and appropriate angle for valve deployment in the cath lab. You need a protocol that helps process imaging data into 3D models to help you better understand a particular patient’s cardiac anatomy and aid in developing an appropriate therapy path and strategy. 

In the cath lab, precise guidance and positioning of planned therapy is crucial. Real-Time 3D working view of the delivery site would facilitate valve deployment.   

Valve Assist

The Valve Planning protocol in the Vessel IQ Xpress application lets you visualize cardiac anatomy with the degree of detail required to evaluate the presentation of the aortic valve. Armed with this information you can develop a pre-procedural TAVR/TAVI plan to establish a therapy strategy for the patient. Innova HeartVision fuses the real time 2D fluoro images on the boom monitor with 3D anatomy overlays from CT, MR, or X-ray data sets, providing guidance for device positioning and deployment with control at tableside.

Highlights

  • Lets you segment the aorta from iliacs to aortic root to select the access route (3D visualization of tortuosity and calcifications).
  • Lets you measure the aortic annulus and define valve plane to select the appropriate device to implant.  
  • Lets you measure the distance between the leaflets and coronary ostia for planning valve deployment.  
  • Gives you the automatically the optimized angle for the intervention.
  • Fuses 3D overlay with 2D fluoro images displayed on Advantage Workstation screen in the cathlab room for guidance. 
  • Registration with ECG gating and image stabilization reduces image motion.  
  • Tableside control for efficient workflow management. 

Features

  • Lets you visualize vessel tortuosity.
  • Enables you to determine calcification load to validate left or right vascular pathways.
  • Lets you segment the aorta for better visualization, and to ascertain aorta diameter and valve-to-ostia measurement.
  • Automatically segments calcifications. 
  • Lets you visualize both iliac artery diameter or profile. 
  • Lets you define the valve plane by contouring the aortic annulus and deposit 3D andmarks on the 3D volume to locate coronary ostia or other areas of interest.
  • Gives you automatic C-Arm angulation perpendicular to the valve plane. 
  • Lets you export the 3D CT images to the cathlab through Innova HeartVision for real time fluoro overlays.
  • With AW Workstation, access to 3D models based on CT or angiography dataset is available in the cath lab. 
  • Dedicated cath lab user interface allows tableside control of 3D images. 

System Requirements

  • Advantage Workstation 
  • VolumeShare 5 (voxtool.11)
  • VesselIQ Xpress.

Intended Use

Valve Planning protocol of VesselIQ Xpress is intended to provide an optimized non–invasive application to analyze vascular anatomy and pathology and aid  in determining treatment paths (TA, TF, TAo, Subclavian) from a set of Computed Tomography (CT) Angiographic images.

Innova HeartVision is intended to enable users to load 3D datasets and overlay and register in real time these 3D datasets with fluoroscopic or radiographic images of the same anatomy in order to support catheter/device guidance during interventional procedures.
