A new patch technique for valve-sparing aortic root repair in acute type A aortic dissection.

ABSTRACT: Valve-sparing aortic root replacement is an attractive option for younger patients with acute type A aortic dissection. This study aimed to design a new patch technique for reconstructing the aortic root and preserving the aortic valve following aortic dissection. Between July 2017 and December 2018, 35 patients underwent valve-sparing aortic root repair using this new patch technique. All participants were in the supine position, transesophageal echocardiography and median sternotomy were routinely performed. After thrombi at the aortic root were removed in acute type A dissection, the luminal aortic intimal dissection was removed until the aortic condition was normalized. In each aortic sinus involved in the dissection, a Dacron-graft patch with the shape corresponding to the defect was
