What is a maze procedure? 

The maze procedure is a surgical approach used to treat atrial fibrillation (AFib). It involves creating a pattern of scar tissue in the atria, which can help block abnormal electrical signals. This may aid in restoring normal heart rhythm and reducing the risk of stroke. 

Who might be a candidate for a maze procedure? 

• Patients with persistent or long-standing AFib. 

• Those who have not responded to medications or catheter ablation. 

• Patients undergoing open-heart surgery for other heart conditions. 

• Patients at increased risk of stroke due to AFib. 

What to expect during a maze procedure 

• The procedure may be performed as open-heart surgery or through a minimally invasive approach. 

• A surgeon typically makes small incisions or applies radiofrequency energy to create scar lines. 

• The resulting scars are intended to disrupt irregular electrical pathways in the heart. 

• The procedure might be combined with other heart surgeries if necessary. 

What are the risks of a maze procedure? 

• Potential for bleeding, infection, or blood clots. 

• Possibility of needing a temporary or permanent pacemaker. 

• Risk of stroke or other heart-related complications. 

• Recovery time may be longer compared to catheter-based treatments. 

What does recovery from a maze procedure involve? 

• A hospital stay of approximately 5-7 days for monitoring. 

• Temporary irregular heartbeats may occur as the heart heals. 

• Medications could be prescribed to prevent clotting and support heart function. 

• A gradual return to normal activities is typically expected over several weeks.
