The FRACTURE Trial is a study where doctors use a special tool called the Bolt Intravascular Lithotripsy System to help treat people with coronary artery disease. This system uses sound waves to break up hard calcium deposits in the arteries, making it easier for a balloon to open them up. This is for people who have stable or unstable angina, silent ischemia, and need a procedure called Percutaneous Coronary Intervention (PCI). Participants must be 18 years or older and cannot have had a heart attack within the last 30 days.

• The study involves using a new treatment method that is not yet approved for regular use.
• Participants will not be randomly selected; everyone in the study will receive the same treatment.
• Some people may not qualify due to recent heart attacks, advanced heart failure, or severe kidney disease.

Consider if you meet the criteria and are comfortable with the study requirements before participating.
