Abstract

In the past several years, there has been an increasing interest in the use of advanced energy modalities such as microwave for ablation of more complex cardiac arrhythmia including atrial flutter, atrial fibrillation and ventricular tachycardia. It has been demonstrated that microwave energy can produce larger and deeper lesions than radio-frequency (RF) energy and therefore clinicians worldwide are interested in using microwave ablation. Thus, the development of efficient microwave generators, catheters and applicators that are well adapted for cardiac tissue ablation is essential. This paper pertains to the physical properties of tissue at microwave frequencies, the theoretical background of microwave ablation and the initial clinical results obtained with the Fidus's microwave ablation system.
