GE Healthcare showcased its Innova EPVision software application that combines 2D and 3D x-ray images and cardiac models from multiple imaging modalities such as CT, x-ray and MRI to help alleviate motion during cardiac procedures by use of image stabilization features, at the recent Heart Rhythm Society (HRS) meeting.

“This CT fluoro fusion product addresses some of the big problems customers have told us about when they overlay a CT and fluoro image. The problem is that during an EP procedure, there are several catheters inside the heart but it's difficult to pinpoint their exact location. There are some reference points, but there also are a lot of things moving,” David Tolan, marketing manager of interventional cardiology and EP told Cardiovascular Business News.

EPVision is helpful in reducing motion artifacts for better image overlay. The live fluoro image serves as a reference point for the catheters as the CT or 3D image is superimposed upon it, said Tolan.

The product’s ECG gating feature allows the cardiac image to slow down to better anticipate catheter placement, he explained.

“EPVision also is tied to respiratory gating so that the image moves with the chest. When the chest is moving, we can track it and also track it in 3D, which enables an electrophysiologist to better visualize the ablation environment."

The Innova EPVision solution is available for the company’s 2100 IQ cardiovascular X-ray system, according to GE.
