What are the risks of angioplasty?
Angioplasty is generally a safe procedure. It relieves the block in the blood vessels and improves the blood supply to the heart muscles. Rarely the block can recur. Occasionally a clot can form in the vessel and occlude it. Very very rarely, the vessel can get perforated during the procedure. But considering the risk of the disease for which it is done, the benefit / risk ratio is high.
