Maze Procedure

According to the American Heart Association at least 2.7 million Americans are living with atrial fibrillation (AFib), a type of heart arrhythmia where the upper chambers (atria) of the heart beat irregularly and rapidly. This irregular atrial beat causes the impulses to pass irregularly to the ventricle (lower chambers), which results in inefficient pumping, reduced blood output, and often low blood pressure with symptoms of dizziness or shortness of breath.

Afib is the most common heart rhythm disorder, but it can be life threatening to some patients. The greatest risk of A-Fib is stroke. When the heart isn’t pumping out properly, blood can pool in the atria and cause blood clots that can travel to the brain, causing stroke. Those with A-Fib have double the risk of heart-related deaths and are five times more likely to have a stroke than the general population.

The Comprehensive Atrial Fibrillation Institute at Florida Medical Center offer a complete range of treatment options for Afib.

Maze Surgery

During maze surgery, surgeons create a “maze” of new electrical pathways in the heart to allow impulses to travel more easily. Surgeons construct these pathways by using an ablation energy source to create scar tissue. The scar tissue blocks the electrical signals that are causing the irregular heartbeat, allowing the normal signals to function properly. This procedure is typically performed on patients who need open heart surgery for another reason, such as a heart valve repair or replacement. If a patient only needs treatment for atrial fibrillation, then it may be treated by catheter ablation instead, a less invasive procedure. This procedure may also be suggested if the less invasive procedures will not be as effective for the patient’s particular condition.
