Right Ventricular Assessment in Adult Congenital Heart Disease Patients With a RV to PA Conduit: Validation of a 3D Knowledge Based Reconstruction Method

Abstract

Assessment of right ventricular (RV) volumes and function is important in congenital heart disease (CHD) patients with RV to pulmonary artery (PA) conduits. Cardiac magnetic resonance imaging (CMR) is considered the reference standard. Three-dimensional knowledge-based reconstruction (3DKBR) derived from two-dimensional echocardiographic imaging with magnetic tracking of the transducer position is a novel approach to RV assessment that has been validated in other CHD populations. The aims of this study were: 1) to determine patterns of RV shape across the spectrum of CHD with RV to PA conduits using CMR; 2) to assess the feasibility and accuracy of 3DKBR of the RV in CHD patients with RV to PA conduits.
