PVS is a life-threatening disease without a clear cause. The investigators think patients who develop PVS have an increased Wall Shear Stress (WSS) level in the pulmonary veins, which is the force placed on the walls of the veins. This study will determine if WSS can be calculated in the pulmonary veins of infants using Ferumoxytol enhanced Cardiac Magnetic Resonance Imaging (FcMRI). If possible, the investigators aim to use FcMRI to better screen patients at risk of PVS and to help guide therapy in patients with PVS.",[69],"Pulmonary Vein Stenosis",[71,72],"Cardiac Magnetic Resonance Imaging","Wall Shear Stress","2026-08-03",{"date":75,"type":76},"2026-08-05","ACTUAL",{"date":78,"type":76},"2024-09-30",{"date":80,"type":63},"2028-06",{"name":5,"class":6},1]
