Le résumé fourni par la source

Motivation: 4D Flow Assessment for Reconstruction Right Ventricular Outflow Tract in Congenital Heart Disease Patients: New Hemodynamic Insights for Handmade Three-Valve Goretex ConduitGoal(s): 1) evaluate pulmonary valve regurgitation and the patency of the Goretex conduit using 4D flow CMR compare with controls. 2) assess the variation of advanced hemodynamic parameters of 2D axial WSS, 2D circumference WSS and EL in Gortex conduit. Approach: The CMR data was acquired from 12 healthy participants and 17 patients who were performed cine sequence in routine chamber view and 4D flow. Results: Hemodynamic changes were detected in patients with right ventricular outflow tract reconstruction. Impact: Further long-term evaluation is necessary for the changes in segmental WSS in MPA.
