Heart bypass upgrade: which Artery-Harvesting technique works best?
NCT ID NCT07720661
First seen Jul 22, 2026 · Last updated Jul 29, 2026 · Updated 3 times
Summary
This trial tests two methods of harvesting the left internal mammary artery for heart bypass surgery. One method strips the artery clean of surrounding tissue; the other leaves the tissue intact. Researchers want to know which approach keeps the graft open longer and reduces the risk of infection and chronic chest pain. About 1,100 adults undergoing planned bypass surgery will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- skeletonized or non-skeletonized harvesting of the left internal mammary artery during coronary artery bypass surgery
- What this could lead to
- If one technique proves superior, it could reduce graft failure, infections, and chronic chest pain after bypass surgery.
- What could go wrong
- This is a surgical technique comparison, not a new drug or device, so improvements may be modest. Results depend on surgeon skill and patient factors.

Inclusion Criteria: 1. Age 18 years or older 2. Undergoing isolated CABG surgery with median sternotomy and a planned LIMA-LAD graft 3. Provision of written informed consent Exclusion Criteria: 1. Non-sternotomy surgical approach (e.g., minimally invasive, thoracotomy) 2. Emergency surgery (defined as surgery required within 24 hours of presentation) 3. History of prior sternotomy 4. Currently receiving systemic antibiotics or with an active bacterial infection at the time of surgery 5. History of chronic sternal pain prior to the index surgery 6. Known left subclavian artery stenosis (\>50%) 7. Previous radiation therapy to the chest 8. Known allergy or contraindication to iodinated contrast media that cannot be managed with premedication 9. Estimated glomerular filtration rate (eGFR) \<30 mL/min/1.73m² at baseline (relative contraindication to CTA contrast) as determined based on each centre's laboratory standard. 10. Known pregnancy or plans for pregnancy during the study period 11. Life expectancy less than 1.5 years due to non-cardiac conditions 12. Inability or unwillingness to comply with follow-up procedures including CTA at 1.5 years
