From: A case report of aortic root repair using a pericardial autograft for type A aortic dissection
a b Removal of the dissection intimal flap to the normal aorta wall at the noncoronary sinus, leaving a 5 mm rim of intimal flap near the commissures and coronary ostia. c d Pericardial autograft patch was used to create a new aortic wall to reconstruct the sinus, coronary ostia, and resuspend the commissures. A pericardial patch was sutured to the aortic adventitia to strengthen the new aortic wall
