Amiodarone Patches Failed to Cut Heart Rhythm Risk
New research shows that applying medicated patches during cardiac surgery did not lower the risk of developing postoperative atrial fibrillation.

A randomized trial involving 502 patients found that amiodarone-soaked patches applied during surgery did not prevent postoperative atrial fibrillation compared to a saline placebo. The findings suggest this specific surgical technique does not offer the expected protective benefit for patients undergoing cardiac procedures.
Why it matters
The study was designed to build on earlier, positive results from an amiodarone hydrogel spray trial, aiming to provide a new preventative strategy for common heart rhythm complications. Because the new technique failed to show significant improvement, it does not currently change the standard of care for cardiac surgical patients.
In a randomized trial of 502 patients, researchers compared amiodarone-soaked cellulose patches to saline-soaked patches during elective cardiac surgery. The intervention showed no statistically significant difference in the incidence of atrial fibrillation or duration of hospital stays within five days.
The players
EACTS
The European Association for Cardio-Thoracic Surgery is a professional organization focused on cardiothoracic surgery research and clinical standards.
Jilin Heart Hospital
A cardiac specialty medical center in China that served as the primary site for patient enrollment in the BEAT-AF clinical trial.
The details
During the procedure, surgeons placed two cellulose patches containing 150 mg of amiodarone per 3 mL of solution over the atrial ganglionated plexuses on the left and right atria. This approach was intended to deliver the drug directly to the heart nerves responsible for regulating rhythm, theoretically suppressing electrical instability after surgery. Despite the targeted application, the patches did not result in lower rates of heart rhythm issues compared to the control group.
Timeline
The BEAT-AF findings were presented at an EACTS meeting on October 13, 2026.
Health Landscape
This study marks a departure from the positive expectations generated by earlier research into amiodarone-based delivery systems for heart surgery. It highlights the challenges in translating localized drug delivery techniques into consistent clinical outcomes for postoperative heart rhythm management.
This trial reinforces that experimental surgical techniques require rigorous testing before being adopted into routine practice. Patients concerned about heart rhythm risks following an upcoming surgery should discuss standard prevention strategies with their surgeon or cardiologist.
The takeaway
The clinical trial confirms that amiodarone-soaked patches were not effective at reducing postoperative atrial fibrillation in this study population. If you are preparing for cardiac surgery, consult your cardiologist about the most evidence-backed methods for reducing your specific risk of heart rhythm complications.
