History, Techniques, and Outcomes of the Reimplantation Method
Annuloaortic ectasia (AAE) mainly comprises diseases causing aortic root dilatation and presents various pathologies such as aortic aneurysm and aortic regurgitation. Particularly, the life expectancy of patients with Marfan syndrome depends highly on AAE accompanied by conditions such as aortic dissection and aortic regurgitation. Historically, full aortic root replacement using a composite valved conduit has generally been performed for this etiology. However, since its development, valve-sparing aortic root replacement surgery has been attracting attention as a surgical procedure that dramatically improves the quality of life of the patient. Of the two kinds of surgery, this paper focuses on the reimplantation method and outlines it with the experiences of the authors.
