A Study to Evaluate Aortic Dilatation in Patients with Conotruncal Abnormalities


About this study

The purpose of this study is to assess operative and postoperative outcomes after aortic valve surgery, evaluate for changes in ascending aorta diameter by comparing pre-operative CT imaging to measurements on follow-up imaging, and examine late outcomes and functional status during the follow-up period with specific focus on mortality, need for re-operation and incidence of aortic dissection.
