For people who suffer from angina and have blockages in the heart a conventional way to treat the condition is to offer angioplasty which helps to widen the narrowed blood vessels and improve blood flow and circulation or a bypass surgery. However there could be people who might be unfit to undergo an angioplasty-like people who have obstructions in arteries that runs the entire length of the artery and is laden with fatty plaques. In these types of arteries opening up of a short segment through angioplasty is ineffective. Even if it is attempted the recurrence rates are very high.
