Tiny electric currents flow through the heart muscle and cause them to contract, squeezing blood throughout the body. This animation shows the electrical system of the heart and how it is driven by a small patch of tissue called the cardiac pacemaker or sinoatrial node.

The heart is accessed through a chest incision (A). The patient's heart function is replaced by the heart-lung machine. The aorta is cut open to reveal a diseased aortic valve (B), which is then removed. A valve sizer is placed in the opening to determine the size of prosthesis needed (C). A prosthetic valve is sutured in place (D and E). (Illustration by Argosy.) The heart is accessed through a chest incision (A). The patient's heart function is replaced by the heart-lung machine.

Other Information

Aortic valve replacement is a cardiac surgery procedure in which a patient's aortic valve is replaced by a different valve. The aortic valve can be affected by a range of diseases; the valve can either become leaky (aortic insufficiency / regurgitation) or partially blocked (aortic stenosis). Aortic valve replacement currently requires open heart surgery.
