This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing two different techniques to treat a specific type of calcium buildup in heart arteries called calcified nodules. These hard calcium deposits can make it difficult for doctors to place stents (small metal tubes) properly during heart procedures. The study will compare orbital atherectomy (which uses a diamond-coated rotating tool to gently abrade the calcium) and intravascular lithotripsy (which uses sonic waves to break apart the calcium) to see which method works better.
Calcified nodules in heart arteries are tricky to treat because the hard calcium makes it difficult to expand arteries properly and place stents effectively. This trial exists to find out which of these two newer techniques is most effective at breaking down this calcium and improving treatment outcomes for patients.

You will be randomly assigned to receive one of the two procedures to treat your calcium buildup. The procedure involves inserting a catheter (thin tube) into your artery and using either the rotating abrasion tool or sonic wave device to break down the calcium before placing a stent. After the procedure, you'll be monitored for 12 months with follow-up visits to check for any complications and see how well the treatment worked.
