The procedure to insert a stent is known as percutaneous transluminal angioplasty (PTA) or percutaneous coronary intervention (PCI). The procedure is usually done through a catheter, which is then inserted into an artery in the leg & led to the blocked artery. Furthermore, the stent is then inflated to open the blocked artery and increase the blood flow. Consult the best cardiologist in Begur for stent treatment.
