Ultrasound-guided heart procedure without contrast dye in kidney disease

This trial is testing a new way to perform heart procedures (called coronary angioplasty) in patients with severe kidney disease. Instead of using contrast dye—which can damage kidneys—doctors will use ultrasound imaging to guide the procedure. The study wants to see if this approach prevents kidney damage that normally occurs in about 1 in 4 patients with severe kidney disease who receive standard heart procedures.

When patients with severe kidney disease receive heart procedures, the contrast dye used during imaging often causes additional kidney damage or even kidney failure. There is no cure for this damage once it happens, so this trial exists to test whether ultrasound guidance can prevent this complication and protect kidney health.
