Every year thousands of people have cardiac catheterizations, or angioplasties. That’s when a doctor threads a catheter to your heart arteries to look for blockages and other issues. If they do see a blockage, they can decide if placing a stent to open it would be beneficial. For years, doctors have used the artery near your groin as an access point for this procedure. But now, some are using the artery in your wrist. Why? Because it may be safer and easier on patients.
