The convergent procedure is a hybrid treatment for long-standing persistent atrial fibrillation, in which the irregular rhythm has lasted for months or years. It combines two approaches. A surgeon first treats the outer surface of the heart through a small incision, and a cardiologist then treats the inner surface with a catheter. Together they create a more complete line of scar that blocks abnormal electrical signals.

Both the cardiac surgeon and the electrophysiologist assess patients seeking cardiovascular care in Mumbai for persistent atrial fibrillation. The convergent approach is considered when catheter ablation alone has not worked or is unlikely to work, for instance, because the left atrium is enlarged or the arrhythmia has been present for a long time. Echocardiography, CT scans and rhythm recordings help decide who is suitable.

The two stages may be done together or on separate days, under general anaesthesia. The surgical stage uses small incisions and a camera, avoiding a large chest opening and the heart-lung machine. Patients usually stay in hospital for a few days. Blood thinners and rhythm medicines continue for a period afterwards, and follow-up includes ECG and rhythm monitoring over several months.

How the Procedure Can Help

The convergent procedure may restore a normal rhythm in people with long-standing atrial fibrillation who have few other options, without open-heart surgery. Restoring rhythm can improve symptoms such as palpitations, breathlessness and fatigue, and may reduce the need for rhythm medicines.

Risks and Considerations

Risks include bleeding, fluid around the heart, stroke, injury to the food pipe or nearby nerves, infection and return of the arrhythmia. Some patients need repeat treatment. The procedure is performed by a specialised team and is not suitable for all patients. Fever, chest pain, difficulty swallowing, breathlessness or sudden weakness afterwards needs urgent medical attention.
