Surgeons develop simpler way to cure atrial fibrillation

Physicians have an effective new option for treating atrial fibrillation, a common irregular heart rhythm that can cause stroke. Heart surgeons at Washington University School of Medicine in St. Louis have developed and tested a device that radically shortens and simplifies a complex surgical procedure that has had the best long-term cure rate for persistent atrial fibrillation.

The simplified procedure is termed Cox-maze IV, and the surgeons believe it can replace the older "cut and sew" Cox-maze III in which ten precisely placed incisions in the heart muscle created a "maze" to redirect errant electrical impulses.

"This technology has made the Cox-maze procedure much easier and quicker to perform," says Ralph Damiano Jr., M.D., the John Shoenberg Professor of Surgery and chief of cardiac surgery at the School of Medicine and a cardiac surgeon at Barnes-Jewish Hospital. "Instead of reserving the Cox-maze procedure for a select group of patients, we would urge use of this device for virtually all patients who have atrial fibrillation and are scheduled for other cardiac surgery."

The device is a clamplike instrument that heats heart tissue using radiofrequency energy. By holding areas of the heart within the jaws of the device, surgeons can create lines of ablation, or scar tissue, on the heart muscle. In the older Cox-maze III procedure, the lines of ablation were made by cutting the heart muscle, sewing the incisions back together and letting a scar form. The ablation lines redirect the abnormal electrical currents responsible for atrial fibrillation, an irregular heart rhythm in which the upper heart chambers or atria wriggle like a bag of worms.

The Cox-maze procedure was developed at the University in 1987. In their latest clinical study, reported in the February issue of the Journal of Thoracic and Cardiovascular Surgery, University surgeons showed that Cox-maze IV is just as effective as Cox-maze III for curing atrial fibri
