The evolving role of MDCT in transcatheter aortic valve replacement: a radiologists' perspective.
OBJECTIVE
The purpose of this article is to familiarize the radiologist with the technical aspects of transcatheter aortic valve replacement (TAVR). The wide range of MDCT imaging findings that are critical for planning and performing TAVR will be reviewed.


CONCLUSIONS
TAVR is developing into an effective and reproducible therapy for aortic valve stenosis. We describe the important role of MDCT in planning and performing TAVR in a large transcatheter valve program.
