Cardiac Vascular Reconstruction DynaCT for TAVI Procedures
Tab Title Description
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
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. 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 TAVI procedure both before and after the TAVI device is implanted. The CAVAREC image processing algorithm will be implemented on an off-line workstation after the TAVI 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 procedures.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.
