This study is looking at a tool called Transit-Time Flow Measurement (TTFM) during coronary artery bypass graft (CABG) surgery. CABG is a type of heart surgery where new paths are created for blood to flow around blocked arteries to the heart. TTFM uses sound waves to check how well blood is flowing through these new paths during surgery. The goal is to see if using TTFM to assess blood flow during surgery helps the new blood vessels (grafts) stay open and improves how patients recover. The study will enroll 1242 participants who are at least 18 years old and having their first, non-emergency CABG surgery. The main way to measure success is to see if any grafts fail within 1 to 3 months after surgery. The current status of this study is unclear.

Study design

Compensation

Not stated in the trial record.

Follow-up
