Handheld ultrasound could spot hidden graft failures during bypass surgery
NCT ID NCT07700524
First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time
Summary
This trial tests whether using a portable ultrasound device during coronary artery bypass surgery can improve outcomes by letting surgeons see blood flow through the new grafts in real time. About 380 adults scheduled for elective bypass surgery will be randomly assigned to either standard care or standard care plus ultrasound monitoring. The study will compare rates of major complications like heart attack, stroke, kidney failure, and death, as well as how often ultrasound detects graft problems that need fixing.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- intraoperative portable Doppler ultrasound
- What this could lead to
- If successful, this approach could become a standard tool during bypass surgery to catch and fix blood flow problems immediately, potentially reducing complications.
- What could go wrong
- This is a single-center trial with 380 patients, so results may not apply to all hospitals. The ultrasound adds time and training, and its benefit over standard surgical judgment is unproven.
