Abstract
Preparation for transcatheter aortic valve implantation (TAVI) requires imaging of the aortic root, aorta, and iliac arteries. Contrast agent exposure can be a problem in TAVI candidates who often have impaired renal function. High-pitch spiral CT allows high-resolution imaging of large volumes in a very short time. We evaluated the ability of high-pitch spiral imaging with dual source CT (“Flash Mode”) and a minimized amount of intravenous contrast to evaluate aortic root anatomy and suitability of vascular access for TAVI procedures.
