Angioplasty, or Percutaneous Transluminal Coronary Angioplasty (PTCA), is a common, minimally invasive procedure used to treat significant blockages (over 70%) in the coronary arteries that supply the heart. It typically follows a diagnostic angiogram and involves inserting a catheter through the radial artery in the wrist or femoral artery in the groin. A balloon is inflated at the site of the blockage to open the artery, followed by placement of a thin mesh-like coronary stent to keep it open. For complex cases—such as heavily calcified blockages, chronic total occlusions, or bifurcation lesions—advanced techniques like rotational atherectomy, orbital atherectomy, intravascular lithotripsy, and imaging tools like IVUS and OCT are used for precision treatment. These methods reduce the need for bypass surgery and improve long-term outcomes. However, stents carry a 2–4% risk of restenosis (re-narrowing), which can be managed with drug-coated balloon treatments. Overall, angioplasty is a safe and effective alternative to surgery for many patients with coronary artery disease.___________________________________________________________________________________
