<p>Heart is the most important organ of the body and any impairment in its function can cause death of a person within minutes. Existing method for the heart cure is open-heart surgery. But the open-heart surgery is a most tedious, difficult, expensive and risky job. It also requires highly sophisticated technology with sophisticated equipment in well-equipped operation theaters.

It is also a preventive technology.</p>
