The U.S. Food and Drug Administration (FDA) has cleared 3D angiography software from Siemens Healthcare.
The company's syngo aortic ValveGuide application helps cardiologists and cardiac surgeons prepare and perform transcatheter aortic valve replacement. The software automatically reconstructs a 3D representation of the aortic root from cross-sectional images acquired with the angiography system and suggests the best projection angle for the valve replacement, according to Siemens.
It also selects anatomic landmarks and overlays the 3D image with 2D images acquired during live fluoroscopy, enabling physicians to obtain real-time 3D guidance while navigating the new valve to its intended location.
Prior to syngo aortic ValveGuide, clinicians have relied on preprocedural (or intraprocedural) CT, manually coregistering images with live fluoroscopy and overlaying them on a live fluoroscopy image to determine the correct angle. Syngo aortic ValveGuide uses Siemens' syngo DynaCT Cardiac software that processes CT-like cardiac images from images acquired using the angiography system, the company said.
