Cardiovascular Magnetic Resonance Imaging Traits Associated with Adverse Right Ventricular Remodeling in Repaired Tetralogy of Fallot.

Background: Deterioration of right ventricular (RV) function in repaired tetralogy of Fallot (rToF) is poorly understood. Cardiovascular magnetic resonance (CMR) is used for monitoring, but its analysis is user-dependent and time-consuming. We sought to automate the analysis of CMR using machine learning, and to identify imaging traits associated with adverse RV remodeling in the natural history of rToF.
