Coronary angioplasty is a minimally invasive procedure to open the blockage in heart's blood vessels and to improve the blood flow. Typically this is done at the same setting of heart catheterization. The physician advances a balloon through a small wire and inflates the balloon to relieve the obstruction. Most of the time a mesh tube structure called "stent" needs to be placed to keep the blood vessel open. Coronary angioplasty and stent placement can be done from the arm or from the groin.
