What is a mini maze procedure?
The mini maze procedure is a minimally invasive surgical treatment used to manage atrial fibrillation (AFib). It involves creating scar tissue on the heart to block abnormal electrical signals that cause irregular rhythms. This approach is a less invasive alternative to the traditional maze procedure and may be done without open-heart surgery.
Who might be a candidate for a mini maze procedure?
-
Patients with persistent or long-standing AFib that has not responded to medications or catheter ablation.
- Individuals who prefer a surgical approach or have had failed prior ablations.
- Patients with symptomatic AFib affecting quality of life.
- Those at high risk for stroke who are not good candidates for other rhythm-control options.
What to expect during a mini maze procedure
- The procedure is typically performed under general anesthesia.
- Small incisions are made between the ribs to access the heart using specialized instruments.
- Surgeons use energy sources like radiofrequency or cryoablation to create lines of scar tissue in the left atrium.
- The left atrial appendage may also be closed off to reduce stroke risk.
What are the risks of a mini maze procedure?
- As with any surgery, risks may include bleeding, infection, or adverse reaction to anesthesia.
- There is a chance of needing a pacemaker if the heart’s rhythm is overly slowed.
- Postoperative atrial arrhythmias or temporary irregular rhythms may occur.
- In rare cases, complications involving the lungs or surrounding structures are possible.
Recovery from mini maze procedure
-
Most patients stay in the hospital for several days, depending on overall health.
- Pain at incision sites and fatigue may be present for a few weeks.
- Heart rhythm monitoring continues to assess for any recurrence of AFib.
- Blood thinners may be continued for a period of time based on individual stroke risk.
- Follow-up includes regular appointments and possibly cardiac rehabilitation.
