Surgery for Arrhythmias (Maze Procedure)

Atrial fibrillation (AF) is the most common heart rhythm disorder affecting millions worldwide. It is characterized by irregular and rapid heartbeats that originate in the atria, the upper chambers of the heart. Unlike a normal heartbeat that starts at the sinoatrial node and travels in a controlled manner through the atrioventricular node, atrial fibrillation results from multiple electrical impulses firing simultaneously across the atria. This chaotic activity leads to an irregular rhythm and reduced cardiac efficiency. If left untreated, atrial fibrillation can be dangerous. It significantly increases the risk of stroke, congestive heart failure, and even mortality. Studies show that atrial fibrillation can double the risk of death and increase stroke risk nearly fivefold. Patients often experience persistent palpitations, breathlessness, fatigue, dizziness, and reduced exercise tolerance. Seeking timely care at a reputed center like Aster RV Hospital under an experienced specialist such as Dr. Divakar Bhat, one of the Best Heart Doctors in Bangalore, is crucial for optimal outcomes. Treating atrial fibrillation with the Maze procedure The Maze procedure is a highly effective surgical treatment for atrial fibrillation. It works by interrupting the abnormal electrical pathways responsible for irregular heart rhythms. During the procedure, the surgeon creates a series of precise incisions or ablation lines in the left and right atria. These incisions heal into scar tissue, which does not conduct electrical impulses, thereby blocking abnormal signals while allowing normal conduction to resume. The result is a single, controlled pathway for electrical impulses—much like navigating a maze with only one exit—ensuring a stable and regular heartbeat. This is why it is called the Maze Procedure. At Aster RV Hospital, advanced approaches such as Key Hole Heart Operation in Bangalore and Robotic Assisted Heart Operations in Bangalore are often used to enhance precision, reduce trauma, and speed recovery. The surgery typically lasts about four hours and can be performed on a beating heart, avoiding the heart-lung machine in selected cases. Recovery and rehabilitation after Maze surgery Most Maze procedures are performed alongside other cardiac surgeries, such as valve repair, valve replacement, or coronary artery bypass grafting. The overall success rate ranges from 60% to 95%, depending on patient factors. Patients with isolated atrial fibrillation generally experience faster recovery and better outcomes compared to those with an enlarged heart or valve disease. Post-surgery, patients are monitored overnight in the intensive care unit and then shifted to a regular ward for 4–8 days. A short course of anti-arrhythmic medications, aspirin to prevent blood clots, and diuretics to manage fluid buildup may be prescribed. Under the guidance of Dr. Divakar Bhat, regarded as one of the Best Heart Surgeons in Bangalore, patients are encouraged to resume light activities within 2–4 weeks. Walking is the most recommended form of exercise during recovery, while activities that strain the chest or upper arms should be avoided. Most patients feel significantly better within six weeks, regaining energy and quality of life.
