The GALAXY procedure is a revolutionary, minimally invasive operation developed at Intermountain Medical Center. The procedure is designed to treat atrial fibrillation without the use of the heart-lung machine and with smaller, less painful incisions. Also known as the "mini-Maze" operation, the GALAXY procedure utilizes specialized equipment and technology.
A small 2-3 inch incision is made in the middle of each side of the chest. Using an operating video camera, catheters and a flexible clamp are placed around the back of the left atrium (Gemini system). Radiofrequency burns are then formed on the left atrium, isolating the irregular impulses of atrial fibrillation. The surface of the heart is also electrically tested to ensure complete elimination of fibrillation. Finally, a thin automatic stapling device is used to remove the left atrial appendage.
The GALAXY procedure is effective at eliminating atrial fibrillation in over 85% of patients. Removal of the left atrial appendage, which cannot be performed with catheters, also reduces the risk of stroke. Most patients leave the hospital within a few days and are able to return to normal activity within a few weeks. Many patients will be able to discontinue blood-thinning and anti-arrhythmic medications within a few months.
