Rotational angiography for preinterventional imaging in transcatheter aortic valve implantation.

Objective: To evaluate the clinical value of 3D rotational angiography, as a tool for imaging and measuring 3D anatomy, coupled with transesophageal echocardiogram (TEE) as preinterventional imaging for transcatheter aortic valve implantation (TAVI) procedures.

Background: TAVI is a growing field in cardiology. An understanding of the 3D anatomy of the aortic root is crucial for patient selection and for the optimal planning and guidance of such procedures.
