Q: I want to know more about stents. How many types are there, their cost and efficacy.

A:Stents are stainless steel tube like devices which are inserted non-surgically by angiography like technique to clear blockages of heart arteries & keep them open. They are one of the biggest advances in angioplasty over the last 10 years and have made angioplasty a very safe procedure with risk factor of less than 0.5%. There are a large variety of stents, the most recent advance has been drug coated stent which have practically been able to abolish recurrence of the blockage.
