Read our Atrial Fibrillation research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
After heart surgery, about 30% of patients develop an irregular heartbeat called atrial fibrillation, which can lead to serious complications like stroke and heart failure. This trial is testing whether a simple surgical procedure called left posterior pericardiotomy—which creates a small drainage opening during your heart surgery—can prevent this irregular heartbeat from developing. Researchers want to see if preventing this complication improves your health and reduces hospitalizations in the years after your surgery.
While early research shows that this drainage procedure reduces irregular heartbeats immediately after surgery, doctors don't yet know whether preventing this complication actually improves your long-term health outcomes. This trial will provide that crucial evidence by following patients over time to see if the treatment truly makes a lasting difference.

If you join this trial, your surgeon will randomly assign you to either receive the drainage procedure during your scheduled heart surgery or to have standard surgery without it. You will be followed up after surgery to monitor whether you develop irregular heartbeats and to track your overall health, including any hospitalizations or complications. The trial involves long-term follow-up to see how you do in the months and years after your surgery.
