Valve-sparing aortic root replacements have acceptable reintervention rates in patients with failed pulmonary autografts after a Ross procedure. In our 50-year-old patient with post-Ross valve-sparing aortic root replacement, we report preoperative and postoperative 4-dimensional flow magnetic resonance imaging capturing changes in peak systolic velocity, 3-dimensional systolic flow profiles, and aortic wall shear stress that may predict a decreased risk of aortic dilation, a common complication in repeated Ross procedures.
