Balloon vs stent: which works best for Rock-Hard heart plaques?

NCT ID NCT06657833

First seen Jun 27, 2026 · Last updated Aug 05, 2026 · Updated 2 times

Summary

This study tests two ways to treat hardened calcium deposits in heart arteries. After using sound waves to break up the calcium, doctors will either place a drug-coated balloon or a drug-coated stent. The trial will follow 128 patients for 9 months to see which approach keeps arteries open better and has fewer complications.
