Key points about mini maze procedure
• The mini maze is a less invasive surgical option for treating AFib.• It may be suitable when medications and catheter ablation have failed.
• The procedure creates scar tissue to interrupt abnormal heart signals.
• Recovery time is often shorter than with open-heart maze procedures.
• Stroke prevention may also be addressed during the procedure.
Overview of mini maze procedure
The mini maze procedure is a surgical method to manage atrial fibrillation using small chest incisions and specialized tools. It aims to interrupt faulty electrical signals in the heart by creating scar tissue. It is less invasive than the traditional maze procedure and may offer an option for patients who have not responded to other treatments.
Candidates for mini maze procedure
Patients who may be considered for the mini maze include those who:
• Have persistent or symptomatic AFib despite medications or catheter ablation.
• Are not undergoing open-heart surgery but still need a surgical rhythm-control option.
• Are experiencing AFib that significantly affects daily life or poses stroke risk.
• Have had multiple unsuccessful catheter ablations.
Preparation for mini maze procedure
• Preoperative evaluations may include an ECG, echocardiogram, and blood work.
• Blood thinners may be adjusted before surgery.
• Patients are typically advised to stop eating and drinking several hours beforehand.
• A hospital stay is required, and arrangements should be made for post-discharge care.
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.
Risks for mini maze procedure
While generally well tolerated, the mini maze procedure may involve:
• Bleeding, infection, or anesthesia-related complications.
• Temporary or permanent arrhythmias requiring additional treatment.
• The need for a pacemaker if heart rhythm slows excessively.
• Rare complications involving lung or nerve tissue due to incision placement.
