Fusion Imaging for Structural Heart Disease Interventions

Abstract

Purpose of Review Accurate procedural guidance is necessary for structural heart disease (SHD) interventions to reduce procedural times and improve results. Fluoroscopy remains the foundation imaging modality for guidance of transcatheter therapy. However, fluoroscopy has limitations in that it only provides 2D projections of complex 3D anatomy. Fusion technology has the capability to project cardiac imaging, including echocardiography and computed tomography (CT), onto fluoroscopy for a more complete representation of the anatomy to help guide SHD interventions. This in turn allows for a more effective workflow that may improve safety and efficacy while decreasing procedural times, radiation exposure, and contrast dosage. This review focuses on the use of fusion imaging for SHD interventions.
