The Role of Cardiac Computed Tomography in Valve Disease and Valve Intervention Planning

Purpose of review This review aims to provide an overview of cardiac CT role in detection of valvular lesions and in transcatheter valve replacement. Recent findings Modern CT scans and protocols allow valve evaluation with high spatial and temporal resolution with reduced radiation dose. Cardiac CT is now mainstay of transcatheter aortic valve replacement (TAVR) planning. It plays a role in sizing of transcatheter aortic valve prosthesis, risk assessment for potential complications, prediction of ideal fluoroscopic angles, and selection of vascular access. Cardiac CT's role in transcatheter mitral, pulmonic, and tricuspid valve replacements has evolved in conjunction with these new procedures. We summarize the role of cardiac CT in the context of valvular diseases and transcatheter valve replacement planning.
