Cardiac Ablation Techniques
Cardiac ablation, which is also referred to as 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. Depending on your condition, 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 fully equipped EP labs 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 have substantial experience in this complex procedure, which involves mapping and ablation of the epicardium (the area outside of the heart) for the 15 to 20 percent of people whose ventricular arrhythmia occurs on the heart’s outer surface.
