A very small aortic root and annulus (≤17 mm) needs extensive aortic annular enlargement in adult patients. This report describes a technique that enlarged the aortic annulus by 5 valve sizes from 16 to 17 mm to size 27 bovine pericardial valve, as well as a modification of the aortotomy with the roof technique to make the aortotomy closure easier and more hemostatic while enlarging the sinotubular junction and proximal ascending aorta effectively for future valve-in-valve transcatheter aortic valve replacement.
主动脉根部和瓣环非常小（≤17mm），成人患者需要广泛扩大主动脉瓣环。本报告描述了一种技术，可将主动脉瓣环从 16 毫米扩大至 17 毫米，以适应 27 号牛心包瓣，并对主动脉切开术进行改良，采用 roof 技术，使主动脉切开术的闭合更容易，止血更有效，同时有效扩大窦管交界和升主动脉近端，为未来的经导管主动脉瓣置换术提供条件。
