Commissure holder: an innovative device for aortic valve-sparing technique.
The key to obtaining maximal valve coaptation from the aortic valve-sparing procedure is in appreciating the optimal geometry of each component of the aortic root. We describe a new device called the Commissure Holder (patent pending) that aids in the selection of an appropriate graft size and in the determination of the optimal position at which each commissure should be sutured to the graft.
