The basic function of the heart is to pump the blood which is then circulated to the entire body. Heart failure occurs when the heart fails to pump enough blood to meet the body’s needs. 

Now a days heart failure has become a common ailment across the globe and is the root cause of many heart-related diseases.

Most common causes of heart failure:-

• Blockage of the arteries (coronary heart disease).
• Heart attack.
• High blood pressure.
• Heart valve problems.
• Diabetes.
• Lung diseases.
• Genetic problems in the heart muscles.
• Heart infections.
• Excessive intake of alcohol.

A VAD, also known as a mechanical circulatory support device, is an implantable mechanical pump that helps pump blood from the lower chambers of your heart (the ventricles) to the rest of your body. A VAD is implanted into the abdomen or chest and attached to a weakened heart to help it pump blood to the rest of your body.
