Coronary Bypass surgery is a heart surgery that has been performed over the past 3 decades to clear blocked or clogged arteries. This block develops due to storage of excess fat, cholesterol or other substances making blood flow to the heart, difficult.

The surgery is done using blood vessels from different parts of the body, either from a long vein in the leg or an artery from the chest wall, or any other part of the body which is used to create a new route or "bypass" around the blocked artery and thus improving blood flow to the heart. This will ensure normal functioning of the heart with sufficient amount of oxygen-content blood flow passing through the new vessel to the heart muscles. Depending on the number of clogged arteries, the patient may need to undergo that equal amount of bypass surgeries.

In a Coronary Bypass surgery the heart is not opened to operate rather the heart is stopped, and the breastbone or sternum is divided, while blood is flown through a heart lung machine or a pump oxygenator. This surgery is usually performed to make the patient relief himself of pain and not to prolong one's life. It is considered to be the most common heart surgery. However the coronary bypass surgery may not always be successful and may prove to be fatal at times.

A coronary bypass surgery can be performed in emergency situations or is scheduled for a time when it is best for the patient and the surgeon. The surgery must not be performed if the patient is suffering from any other illness, fever or even if you are victim to coughs and colds. If the patient is experiencing any of these illnesses or symptoms of the same, the doctor or surgeon must be thoroughly versed about it as it can affect your recovery and health during a Coronary Bypass surgery.

The slow flow of blood to the heart or no flow at all results in individuals experiencing a certain unbearable chest pain or a feeling of fatigue or even a heart attack indicates the need for a coronary bypass surgery. Angioplasty is first performed to clear the clogged blood vessels and if it fails then bypass surgery is your next option.

The coronary heart surgery has a success rate of 98 percent and it is estimated that at least 260,000 patients undergo this surgery annually in the United States. Once the surgery has been performed the patient is sent to an intensive care unit for recovery. A regular monitoring of the heart rate and blood pressure is taken into record. The coronary bypass surgery does improve blood flow to the heart making in function normally but it might not be a complete cure to the disease.

New blockages or clogs occurring is a possibility but can be dealt with and avoided if the patient follows a healthy diet and a healthy lifestyle , while avoiding and rather quitting bad habits like smoking, alcohol and drugs.
