Cardiac Vascular Reconstruction DynaCT for TAVI Procedures

Summary

The purpose of this work is to evaluate the feasibility of a new Cardiac Vascular Reconstruction (CAVAREC, Siemens Medical Systems, Germany) image reconstruction algorithm for use during transcatheter aortic valve implant (TAVI) procedures or interventional procedures to treat congenital or structural heart disease. CAVAREC utilizes the same x-ray projection images as currently acquired for clinical DynaCT. X-ray image acquisition to allow CAVAREC will occur during the interventional procedure after the TAVI device, other valve, or stent is implanted. If the participants already have a surgically-implanted TAVI device, stent or other device, and are having a cardiac catheterization, then an extra set of images will be acquired after your clinical care is complete, but before you leave the procedure room. The CAVAREC image processing algorithm will be implemented on an off-line workstation after the interventional procedure is complete. After the TAVI procedure, CAVAREC images will be quantitatively and qualitatively compared to Siemens DynaCT and cardiac CT images from Radiology. The results of this study will be used to direct further development of CAVAREC toward the end goal of providing improved imaging capabilities to guide TAVI, congenital heart, or structural heart treatment procedures.

Conditions

  • Aortic Valve Disease

Interventions

OTHER

CAVAREC Image Processing algorithm

After deployment of the TAVI prosthesis, other trans catheter valve, or stent, but before the patient care episode is completed, a set of rotational x-ray angiography images will be acquired and reconstructed using the clinical DyanCT and research CAVAREC algorithms.
