3D model with fluoroscopy (heart imaging)

Potential of fusion imaging and automated three-dimensional cardiac segmentation during transcatheter aortic valve replacement.

3D model aortic root and left ventricle with fluoroscopy.

Cardiac transcatheter aortic valve replacement (TAVR) is the preferred procedure for aortic valve replacement.

Preprocedural multidetector computed tomography (MDCT) for aortic root analysis and valve prosthesis sizing is considered the standard of care.

However, the use of an iodinated contrast agent during MDCT angiography carries a significant nephrotoxicity risk in patients with chronic severe renal failure. Three-dimensional (3D) transesophageal echocardiographic (TEE) imaging is considered a valuable alternative for aortic root size in this population.
