Circulatory surgery focuses around the areas of the heart and brain.

The Surgeries

Open Heart Surgery
Cardiac surgery is surgery on the heart and/or great vessels performed by a cardiac surgeon. Frequently, it is done to treat complications of ischemic heart disease (for example, coronary artery bypass grafting), correct congenital heart disease, or treat valvular heart disease created by various causes including endocarditis. It also includes heart transplantation.

Coronary Bypass Surgery
Coronary artery bypass surgery, also coronary artery bypass graft surgery, and colloquially heart bypass or bypass surgery is a surgical procedure performed to relieve angina and reduce the risk of death from coronary artery disease.

Valve Replacement Surgery
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. As of 2006, percutaneous aortic valve replacement is being researched, which allows the implantion of valves using a catheter without open heart surgery.

Cataract Surgery
Cataract surgery is the removal of the lens of the eye (also called "crystalline") that has developed an opacification, which is referred to as a cataract.
