“Double Jacket Wrapping” Root Reconstruction for Acute Type A Aortic Dissection

Abstract

This report describes a simple and effective method of aortic root repair and reconstruction in acute type A aortic dissection to reduce the risks of hemorrhage and late aortic root new intimal tear and dilation. "Double jacket wrapping" (DJW) has 2 steps: the first jacket is used for aortic root "sandwich" repair, with a patch between the outer and inner layers; and the second jacket is wrapped outside the reconstructed root at the level of the supracoronary ostium. Compared with aortic root replacement, the DJW method may avoid prosthetic valve-related complications and decrease the complexity of valve-sparing root replacement; thus, DJW is a method worthy of wide use.
