Description
Transcatheter aortic valve implantation (TAVI) was first performed in 2002. With the Edwards-Sapien valve, more than 20,000 to 25,000 TAVI procedures have now been performed worldwide. In this paper, we share our experience using live three-dimensional (3D) transesophageal echocardiography (TEE) to guide and monitor TAVI. At our medical center, we have performed more than 150 transfemoral TAVI procedures. Three-dimensional TEE is useful for precise measurement of the aortic annulus in multiple planes, confirming aortic valve stenosis severity and morphology, monitoring of the position of guidewires and catheters, identifying the ventricular and aortic edges of the valve stent, and optimizing bioprosthetic valve positioning. Post-deployment 3D TEE is also used to assess the severity of residual aortic regurgitation as well as to identify potential complications of the procedure including valve malpositioning.
