Limited-Access Zero-Contrast BASILICA Transcatheter Aortic Valve Replacement.

ABSTRACT:

Objective

Severe anaphylactic reactions to intra-arterial contrast agents, access site limitations, and high-risk coronary artery occlusion may all possibly prohibit the success of a transcatheter aortic valve replacement (TAVR). We describe a case including all 3 of these components and demonstrate the importance of multimodality imaging, including computed tomography (CT), fluoroscopy, and trans-esophageal echocardiography (TEE).

Key steps

1) Obtain orthogonal BASILICA angle from CT. 2) Set up a single femoral access for BASILICA and subsequent TAVR. 3) Place a coronary wire with the radial opaque part at the noncoronary cusp (NCC) from an ulnar artery. 4) Perform TEE with fluoroscopic guidance on BASILICA without intra-arterial contrast agent. 5) Use coronary wire as a ma
