A surgical procedure called catheter ablation is better than oral medication in treating atrial fibrillation, a disorder marked by irregular heartbeat that affects 10 million people worldwide. A trial fibrillation, which causes the heart’s upper chambers to quiver instead of beating, can cause blood clots, increasing the risk of stroke and heart failure. Sixty-six per cent of 167 atrial fibrillation patients who had not responded to oral medication were free of recurrent symptoms a year after they were treated with catheter ablation. The process involves inserting a tube through the blood vessels into the heart, and using radio frequency energy to burn off the abnormal tissue that triggers the irregular heartbeat.
