Percutaneous coronary interventions (PCI) are now well established as a standard means of effective treatment of coronary artery disease. Every year, millions of patients around the world benefit from these procedures that treat blockages in the c
Percutaneous Transluminal Coronary Angioplasty (PTCA) is done under local anesthesia and involves manipulating a catheter under fluoroscopic guidance to the opening of the coronary artery, following which a thin guidewire is threaded across the blockage in the vessel. Subsequently, a balloon is tracked over the wire and inflated to push the blockage to the sides and pave the way for good blood flow. A stent is then deployed there, which acts as a scaffold to prevent recoil and vessel closure.
