All types of AFib can be treated with the maze procedure. The procedure is conducted through small incisions to create scar tissue and block abnormal signals.
The maze procedure normally takes place during open heart surgery. The maze procedure aims to create scar tissue to block the abnormal signals causing AFib. One method of creating scar tissue may be through the use of clamps to deliver radiofrequency energy to heat the heart tissue. The maze chamber may also require the removal of a small chamber in the left atrium.
