Annulus downsizing in valve-sparing aortic root replacement predicts aortic valve reoperation in children and young adults
Valve-sparing root replacement is safe and effective for aortic root aneurysms in children and young adults. Early arrhythmias, recurrent regurgitation, and midterm reoperation remain concerns. Graft upsizing or leaflet modification should be considered if ratio of intended graft to preoperative diameter is less than 1.05. Preoperative imaging can guide appropriate graft selection and plication extent to mitigate reintervention risk associated with excessive downsizing.
