Thoracoscopic epicardial radiofrequency ablation for atrial fibrillation

Atrial fibrillation is a condition that affects the heart, causing an irregular pulse. It occurs when the electrical impulses controlling the heartbeat become disorganised, so that the heart beats irregularly and too fast. When this happens, the heart cannot efficiently pump blood around the body. This may cause symptoms such as palpitations, chest pain or discomfort, shortness of breath, dizziness and fainting. Atrial fibrillation increases the risk of blood clots and stroke. In thoracoscopic epicardial radiofrequency ablation, selected areas of the heart are destroyed using heat, with the aim of preventing the occurrence or conduction of abnormal electrical activity. The procedure is done through small incisions in the chest and using a camera.
