457 Single Vs Biplane 3d Augmented Overlay Guidance To Assist Congenital Cardiac Catheterisation Interventions

Abstract

Introduction: Patients with congenital heart disease (CHD) undergoing cardiac catheterisation procedures often require higher radiation and contrast usage as it is often difficult to track catheter movement through complex anatomy. On a prior study, we showed reduction in need for radiation exposure and contrast usage using a fused single plane fluoroscopy display augmented by 3D magnetic resonance imaging (MRI) and Computed Tomography (CT) models. Recently, a biplane fusion overlay system was made available, which was hypothesised to be of higher benefit as congenital interventions are traditionally performed on a biplane system.
