Potential Role of Three-Dimensional Rotational Angiography and C-Arm CT for Valvular Repair and Implantation
Imaging modalities utilized in the interventional cardiology suite have seen an impressive evolution and expansion recently, particularly with regard to the recent interest in three-dimensional (3D) imaging. Despite this, the backbone of visualization in the catheterization laboratory remains two-dimensional (2D) X-ray fluoroscopy and cine-angiography.New imaging techniques under development, referred to as three-dimensional rotational angiography (RA) and C-arm
CT, hold great promise for improving current device implantation and understanding of cardiovascular anatomy. This paper reviews the evolution of rotational angiography and advanced 3D X-ray imaging applications to interventional cardiology.
