Key-Lock Type Mini-Sternotomy: An Alternative Approach for Adult Cardiac Operations

An alternative technique for minimally invasive aortic valve replacement and atrial septal defect repair is described. After a 5-cm skin incision, a key-lock type sternotomy is made. Excellent exposure of the right atrium and aortic valve was achieved. The configuration of the mini-sternotomy (or the lock) limits the movement of the sternal surfaces (or the key) on the lateral and craniocaudal directions.
