Is your patient a good candidate for catheter ablation?

This section of the web site is designed to help you find the most appropriate care for your patients suffering from heart racing.

Catheter ablation may be performed with a number of energy sources, including hyperthermic modalities such as radiofrequency and microwave energy and hypothermic modalities generally referred to as cryoablation.

The use of radiofrequency (or RF) ablation is the mainstay in the treatment of cardiac arrhythmias. It is successful in treating a number of arrhythmias but is associated with risks of inadvertent damage to adjacent structures, cardiac perforation and thrombotic complications.

Currently, cryoablation is approved only for patients with the most common type of supraventricular tachycardia. However, studies have shown that the procedure is also safe and effective in the treatment of Wolff-Parkinson-White syndrome, atrial flutter and atrial fibrillation.

Generally, electrophysiologists who add cryoablation to their practice do so because it offers a very high level of safety. Features such as cryoadhesion (for greater stability) and cryomapping (for pre-ablation site-testing) contribute to its safety profile.
