Philips Encourages CT Preplanning for TAVI Patients
It is important to utilize computed tomography (CT) in pre-planning for transcatheter aortic valve implementation (TAVI), according to Philips, and there are benefits from viewing CT images via the Philips IntelliSpace Portal. TAVI, performed under fluoroscopic and echocardiographic guidance, is a valve replacement procedure that reduces mortality by 61 percent for patients with severe aortic stenosis who are not candidates for surgery.
The Philips IntelliSpace Portal has numerous applications useful for pre-planning TAVI procedures:
- The Cardiac Viewer aids in performing general viewing operations;
- Advanced Vessel Analysis (AVA) enables analysis of the TAVI catheter access route to reduce risk of vascular injury;
- Comprehensive Cardiac Analysis determines angles for visualization during deployment in the cath lab; and
- Heartbeat CS assesses the amount and distribution of calcium in the valve.
Additionally, using CT to help guide appropriate C-arm angles for initial X-ray positioning can save time and assist with proper dose management.
TAVI has been widely performed in Europe since 2007 and is no longer viewed as experimental. Transcatheter aortic valve replacement (TAVR) devices gained U.S. Food and Drug Administration (FDA) approval in late 2011.
