Summary

This study tested whether removing the ligament of Marshall during coronary artery bypass surgery could prevent a common complication: atrial fibrillation. 220 high-risk patients were randomly assigned to get the extra procedure or standard surgery alone. The goal was to see if this simple addition could safely reduce irregular heartbeats in the week after surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Ligament of Marshall resection (surgical procedure)
What this could lead to: If successful, this simple surgical step during bypass surgery could lower the risk of dangerous heart rhythm problems after the operation, leading to safer recoveries.
What could go wrong: This is a completed trial, but the procedure adds surgical time and risk. It may not work for all patients, and benefits might be small or limited to certain high-risk groups.
