Catheter ablation - Wikipedia, the free encyclopedia: "Catheter ablation is an invasive procedure used to remove a faulty electrical pathway from the hearts of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardias (SVT) and Wolff-Parkinson-White syndrome.
It involves advancing several flexible catheters into the patient's blood vessels, usually either in the femoral vein, internal jugular vein, or subclavian vein. The catheters are then advanced towards the heart and high-frequency electrical impulses are used to induce the arrhythmia, and then ablate (destroy) the abnormal tissue that is causing it.
Catheter ablation is usually performed by an electrophysiologist (a specially trained cardiologist) in a cath lab.
Catheter ablation of most arrhythmias has an extremely high success rate.[citation needed] For SVT, WPW, and atrial flutter, the success rates are 95-98%.[citation needed] For automatic atrial tachycardias, the success rates are 70-90%.[citation needed] The potential complications include bleeding, blood clots, pericardial tamponade, and heart block, but these risks are very low, ranging from 0.5-3%.

Jack's abnormal tissue is located right posterior septal (back of the right side of his heart). Kind of a tricky spot, but Dr. Dick is confident and very reassuring.
