Understanding fluoroscopic cardiac anatomy can facilitate optimal positioning and deployment of prostheses during transcatheter valve repair/replacement, left atrial appendage occlusion, septal defect closure, and paravalvular leak closure. It is possible to use multislice computed to- mography to determine optimal fluoroscopic viewing angles for such transcatheter therapies. The purpose of this paper is to describe how optimal fluoroscopic viewing angles of left-sided heart structures can be obtained using computed tomography. Two- and 3-chamber views are described and may become standard in the context of transcatheter structural heart interventions.
