Multimodal Imaging of Aortic Annulus and Root Geometry After Valve Sparing Root Reconstruction

This article addresses the controversy surrounding the optimal annular stabilization technique following valve sparing root reconstruction (VSRR) and the lack of comprehensive imaging data in the evaluation of the natural history of aortic root graft geometry, valve competency, and prognosis postreconstruction. Seventy consecutive patients were prospectively enrolled between 2008 and 2017 (mean age 56.4 ± 16.4 years, 19.7% women) for VSRR. Dacron aortic annuloplasty reconstruction was found to be stable over time, without the need for external or internal stabilization. Computed tomography imaging was found to be more reliable than echocardiographic images, although given the noted stability, the authors conclude that it was of little utility.
