Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Coronary Stenting involves placing a metal mesh in a blood vessel in the heart to open a blockage. The stent is inserted through a blood vessel in the arm or leg and is put in place by inflating a balloon inside the stent. The stent cannot be removed from the blood vessel once it is in place.
