This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial compares two different approaches to fix a problem called stent under-expansion — when a heart stent doesn't fully open or has narrowed over time. Some patients will receive intravascular lithotripsy, a newer technique that uses sound waves to help open the stent, while others will receive standard balloon treatments. The study wants to see which approach works better and causes fewer problems down the road.
When heart stents narrow or fail to fully expand, especially in calcified (hardened) arteries, current treatment options often don't work well and patients can have chest pain or heart problems again. Doctors hope the newer sound-wave technique might be safer and more effective, but more research is needed to prove it.

You will undergo heart imaging called OCT (optical coherence tomography) to see inside your stent. Then you'll be randomly assigned to receive either the sound-wave technique or traditional balloon treatment to fix the narrowed stent. After the procedure, you'll have follow-up visits to check how well the treatment worked and monitor your heart health. The study involves hospital visits for the procedure itself and follow-up appointments as scheduled by the research team.
