aortic valve replacement surgery may be done as an open-heart surgery or as a less invasive surgery. in open-heart surgery, the surgeon makes an incision in the middle of the chest and cuts through the breastbone (sternum). in less invasive surgery, the surgeon makes smaller incisions and does not open the chest.
in less invasive surgery, the surgeon may make an incision between the ribs
