Stent and Angioplasty:
A stent is a mess tube used to treat narrow or weak arteries (blood vessels that carry blood away from the heart to other parts of the body). The stent is placed in the artery as part of an Angioplasty procedure. Angioplasty restores blood flow into narrow or blocked arteries. The stent helps to support the inner wall of the artery after the angioplasty.

Doctors also place stents in weak arteries to improve blood flow and prevent arteries from bursting. Valve Replacement
If one or more of the valves in your heart is diseased or damaged, it can affect he way your blood flows through your heart by obstructing the flow of blood. This is called valve stenosis or narrowing. It also may allow blood to leak backwards. This is called valve regurgitation, on a leaky valve. Valve replacement is when the diseased valve is replaced with a new one. The most common types of replacement valves are mechanical (artificial) valves or tissue (animal) valves In the operation, a surgeon makes an incision down your breast bone, opens up the heart to reach the valve and performs the replacement. Bypass Surgery

If you have coronary heart disease the doctor might suggest a bypass operation to improve the blood supply to your heart muscle. Your arteries narrow when fatty deposits build up on the inner walls of your arteries. The aim of bypass surgery is to get around the narrowed sections of your coronary arteries. The surgeon does this by grafting a blood vessel in the middle of the aorta and the coronary artery. In most operations, the breastbone is cut. However in some, the breastbone doesn’t need to be – this is called minimally invasive surgery. A heart-lung bypass machine circulates the blood around the body while the surgeon operates on your heart. If the machine isn’t used it is called beating heart surgery. The benefits are that most people get excellent relief from angina and an improved quality of life. Heart Transplant
