Concomitant Aortic Root Replacement With Anterior Konno Annular Enlargement

The need for concomitant aortic annular enlargement and aortic root replacement may be necessary in situations of multilevel left ventricular outflow tract obstruction and/or prior aortic or aortic valve surgery, particularly in the setting of congenital heart disease. It can be extremely tedious and fraught with numerous complications. Major challenges include bleeding in difficult-to-reach areas and the potential need for subsequent operations. This article describes a technique of concomitant aortic annular enlargement and aortic root replacement that minimizes the risk of significant blood loss and facilitates future surgery should it be necessary.
