Potential Value of Fusion Imaging and Automated Three-Dimensional Heart Segmentation During Transcatheter Aortic Valve Replacement

Transcatheter aortic valve replacement (TAVR) has become the preferred procedure for aortic valve replacement.1 Preprocedural multidetector computed tomographic (MDCT) imaging for aortic root analysis and prosthetic valve sizing is considered standard of care.2 However, the use of iodinated contrast agent during MDCT angiography bears a significant nephrotoxicity risk in patients with chronic severe kidney failure. Three-dimensional (3D) transesophageal echocardiographic (TEE) imaging is considered a valuable alternative for aortic root sizing in this population.
