This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a procedure called radiofrequency left atrial posterior wall isolation — a type of heart tissue treatment applied during your heart surgery — can prevent a common complication called postoperative atrial fibrillation. Atrial fibrillation is an irregular heartbeat that occurs in many patients after heart surgery and can lead to serious problems like stroke, heart failure, or a longer hospital stay. The study compares patients who receive this treatment during surgery to those who do not.
Irregular heartbeats after heart surgery happen in up to 6 out of 10 patients and can cause serious complications and longer hospital stays. Doctors want to know if applying this tissue treatment during your surgery can prevent this problem before it starts, rather than waiting to treat it afterward.

If you are eligible and join this trial, you will be randomly assigned to either receive the radiofrequency treatment during your already-planned heart surgery or to receive standard surgery without this additional treatment. The treatment itself happens while you are asleep during surgery and adds no additional incisions or recovery time. Your doctors will then monitor you after surgery to see whether you develop an irregular heartbeat, likely through standard hospital follow-up visits and heart rhythm monitoring.
