Heart surgeons test tiny tissue removal to stop dangerous rhythm after bypass

NCT ID NCT07492901

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

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.

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.
