Keyhole heart surgery. Opening in the chest of a patient during keyhole (minimally-invasive) heart surgery. Soft tissue retractors (white) and a metal retractor are being used to keep the chest open. Scissors holding sutures (black thread) can be seen in the foreground. To the right of the scissors is a fibre optic camera (tube and green plastic circle) inserted into the chest. Its pictures are shown on a video screen, allowing the surgeon to view the area being operated upon. Keyhole surgery is less traumatic than open heart surgery, where the sternum is sawn open. Post- operative pain and recovery time are both reduced.
