Radiofrequency ablation

Radiofrequency ablation was born in the 1980s. Doctor Vedel was carrying out a cardiac electrophysiological exploration. After positioning a probe on the His beam area, he had to deliver an electric shock. He noted right afterwards, the onset of a definitive atrioventricular block. He then understood that the probe had directly transmitted the energy of the electric shock because it was in contact with the gel on the rib cage. The His region was irreversibly damaged. The technique has evolved. Initially, the ablation was done by direct application of a high- voltage current inside the heart chambers. This “flashing” generated many serious complications because it was too aggressive. It led…

Radiofrequency ablation for atrial fibrillation

Radiofrequency ablation is the targeted cautery of cardiac tissue by local application of radiofrequency energy. Target zones are identified during an electrophysiological study, in which a series of catheters are placed in the heart. Accessory pathways or other critical parts of arrhythmia circuits are identified by recording the cardiac electrical activation sequence. Once a target zone is identified, ablation is performed by heating the interface between catheter and endocardium until cell death occurs, at temperatures over 47°C.

Radiofrequency ablation of cardiac arrhythmias: past, present and future

The treatment of cardiac arrhythmias has been revolutionized by the ability to definitively treat many patients with radiofrequency catheter ablation, rather than requiring lifelong medication. This review covers the history of how this has developed and the methods used currently and explores what the future holds for this rapidly evolving branch of Cardiology.

Radiofrequency Catheter Ablation: How to Manage and Prevent Collateral Damage?

Radiofrequency (RF) catheter ablation has become the standard treatment for various arrhythmias and is the first-line therapy for treating many tachyarrhythmias.1 RF ablation adopts a high-frequency (500–750Hz) current to produce lesions through the process of thermal injury. Resistive heating damages the tissue in direct contact with the ablation catheter. Deeper tissues are heated and damaged by heat conduction

What is an arrhythmia radiofrequency ablation?

This article will explain more about what arrhythmia radiofrequency ablation is and what happens during the procedure. It will explain who might need this procedure, and detail the benefits and risks of this surgery. It will also explain what a person in recovery after an arrhythmia radiofrequency ablation might expect.
