Catheter Ablation Techniques
Catheter ablation is a minimally invasive procedure that uses energy to destroy tiny areas of the heart muscle that produce an arrhythmia, or abnormal heart rhythm. It has become one of the go-to solutions for the treatment of atrial fibrillation, ventricular tachycardia, and other arrhythmias. Depending on your condition and circumstances, your Duke electrophysiologist may recommend one of these catheter ablation techniques:
A widely used ablation technique that uses heat to create a larger lesion in the heart tissue more safely. Our four fully equipped electrophysiology laboratories have actively cooled radiofrequency ablation technologies that give electrophysiologists greater control and greater success.
A relatively new approach that uses extreme cold, or cryo energy, to freeze heart tissue when creating a lesion that interrupts errant signals in the heart.
Epicardial Ablation for Ventricular Tachycardia
We are one of the few centers with substantial experience in this complex procedure, which involves mapping and ablation of the epicardium (area outside of the heart) for the 15 to 20 percent of patients whose ventricular arrhythmia occurs on the heart’s outer surface.
