This video demonstrates a Mexican modification to the traditional Maze III procedure, which was initially described by Dr. James Cox. This technique is ideal for patients with mitral valve disease and atrial fibrillation who are undergoing surgery. This modification allows the surgeon to better control the base of the left atrial appendage and the surrounding area, as well as perform the mitral valve procedure more easily. The author has performed this technique in over 50 cases.

After counter clockwise rotation of heart, LA appendage is fully exposed and cut out from outside of LA.
Use 3-0 prolene
This patient has not fragile LA wall.
