Key points about maze procedure
• Maze procedures are effective for long-term AFib management.• They can be performed via open-heart surgery or minimally invasive methods.
• They help reduce the risk of stroke and can improve heart function.
• The procedures can require significant recovery time but offer lasting benefits.
Overview of maze procedure
The maze procedure, which can also be known as the Cox-Maze procedure, treats atrial fibrillation by creating scar tissue to regulate heart rhythm. It is often done alongside other cardiac surgeries.Candidates for maze procedure
The maze procedure is usually recommended for patients with persistent atrial fibrillation who have not responded to other treatment options. It is often considered for patients who are undergoing open-heart surgery for other conditions.Other candidates may include:
• Patients with long-standing or severe AFib.
• Those who have failed medication or catheter ablation.
• Patients who are at high risk of stroke due to AFib.
• Patients already scheduled for open-heart surgery.
Preparation for maze procedure
Patients undergo tests like echocardiograms and may need to adjust medications before surgery.During the procedure, the surgeon makes incisions or uses energy sources to create scar lines toprevent abnormal electrical impulses from spreading in the future.
The maze procedure is performed under general anesthesia with a hospital stay required.
Recovery from maze procedure
Recovery from the Maze Procedure can take several weeks and requires careful monitoring. Patients should follow post-surgery guidelines for the best outcomes.• The hospital stay can last 5-7 days, typically.
• Temporary irregular heartbeats (arrhythmias) are common as the heart heals.
• Blood thinners may be prescribed to prevent clot formation.
• Patients gradually return to normal activities over 4-6 weeks.
• Cardiac rehabilitation may be recommended. .
Risks for maze procedure
As with any heart surgery, the maze procedure carries some risks. These risks should be weighed against the potential benefits of long-term AFib management. Risks can include:• Bleeding, infection or blood clot formation.
• Temporary or permanent need for a pacemaker.
• Stroke or other heart-related complications.
• Prolonged healing and recovery time compared to catheter ablation.
• Possibility of AFib recurrence, requiring further treatment.
