Atrial fibrillation of the heart, sometimes called afib, is an abnormal, irregular and often rapid heart rhythm caused by improper atrial cardiac electrical impulses. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly which causes them to be out of coordination with the beating of the hearts two lower chambers called the ventricle. This can interfere with normal pumping of the blood to the body.
Symptoms of atrial fibrillation often include heart palpitations, shortness of breath and generalized weakness. While atrial fibrillation can sometimes be treated with medications, surgery may be necessary in some cases.
MAZE SURGERY FOR ATRIAL FIBRILLATION
Atrial fibrillation of the heart, sometimes called afib, is an abnormal, irregular and often rapid heart rhythm caused by improper atrial cardiac electrical impulses. It can be associated with a high risk for stroke and eventual weakening of the heart muscle. The most common treatment for afib is percutaneous ablation by an electrophysiologist, but can require MAZE.
MAZE is a surgical ablation procedure that can be used to correct atrial fibrillation. It involves creating multiple lesions with different forms of energy (freezing or heating) arranged in a maze-like pattern in the atria of the heart to force electrical impulses that stimulate heartbeat to ventricles to restore normal heart rhythms.
MAZE can be performed in conjunction with other open heart surgeries if necessary. However, MAZE surgeries can be performed as standalone, minimally invasive procedures using small incisions and specialized instruments. Because minimally invasive surgery involves smaller incisions, it allows patients to heal faster, shortens hospital stays, reduces the likelihood of infection and allows people to return to normal activity sooner.
MAZE WITH OTHER HEART SURGERY
Atrial fibrillation is very common in people who may require heart surgery for other reasons. For this reason, it is very common for cardiac surgeons to correct atrial fibrillation during other types of minimally invasive or open heart procedures.
