5 - 7 daysArrhythmia surgery refers to surgical procedures used to correct abnormal heart rhythms—known as arrhythmias—that do not respond well to medications or catheter-based treatments. The goal of arrhythmia surgery is to restore a normal rhythm by interrupting the abnormal electrical pathways in the heart that are causing irregular beats. This treatment is often considered when arrhythmias pose a significant risk to health or quality of life.
Surgery is typically recommended when other treatments such as medications or catheter ablation fail to control the arrhythmia effectively. It is also used for patients with life-threatening rhythm disorders, such as atrial fibrillation (AFib), ventricular tachycardia, or Wolff-Parkinson-White syndrome, especially when they are associated with other heart conditions requiring open-heart surgery. For example, if a patient is already undergoing bypass or valve surgery, arrhythmia correction may be done at the same time.
The most common arrhythmia treated with surgery is atrial fibrillation, particularly in patients who need surgery for other heart issues. Surgical options are also available for other types of arrhythmias, including atrial flutter, supraventricular tachycardia (SVT), and ventricular arrhythmias. The type of surgery depends on the specific arrhythmia and the patient’s heart condition.
The Maze procedure is one of the most well-known surgical techniques used to treat atrial fibrillation. During this surgery, the surgeon creates a series of precise incisions or ablations (burns or freezes) in the upper chambers of the heart. These incisions form a pattern, or "maze," of scar tissue that blocks the abnormal electrical signals and allows electrical impulses to follow a normal path. The result is a restoration of the normal heart rhythm.
Minimally invasive arrhythmia surgery involves using small incisions and specialized tools, sometimes with robotic assistance, to perform the same electrical pathway interruptions without opening the chest completely. This technique is less traumatic than traditional open-heart surgery and usually results in shorter recovery times, less pain, and a reduced risk of complications.

Arrhythmia surgery can be done in different ways depending on the method used. In traditional surgery, the chest is opened, and the heart may be stopped temporarily with a heart-lung machine. In minimally invasive approaches, the surgeon accesses the heart through small incisions between the ribs using video-guided tools. The abnormal electrical pathways are destroyed or altered using surgical cuts, radiofrequency energy, or cryotherapy.
Recovery depends on the type of surgery performed. After open-heart arrhythmia surgery, patients usually stay in the hospital for about 5 to 7 days and require several weeks of rest and follow-up. Minimally invasive procedures typically have faster recovery times, with many patients returning to normal activities within 2 to 3 weeks. Patients are monitored regularly to ensure the heart rhythm remains stable and to adjust medications if necessary.
As with any surgery, there are potential risks, including bleeding, infection, stroke, or damage to the heart or surrounding organs. There is also a small chance that the surgery may not completely correct the arrhythmia, requiring further treatment. However, in specialized centers with experienced cardiac surgeons, the risks are minimized, and the success rates are high, especially for atrial fibrillation surgery.
