Abstract:
We present a report on reinforcement of the proximal anastomosis during the Bentall operation. The aortic wall was excised with a 5-mm remnant, and aortic valve leaflets were preserved. Interrupted horizontal mattress sutures (2-0 Polyestel) reinforced with pledgets were placed. The composite graft was placed at the intraannular position inside of the preserved leaflets. The aortic valve leaflets were then pasted to the sewing cuff with fibrin glue. A running suture with 4-0 monofilament was placed between the remnant of the aortic wall and the peripheral side of the sewing cuff wrapped with native aortic valve leaflets.
