What type of lesion is made at the distal electrode during the Simplicity procedure?

In the Simplicity procedure, the lesion created at the distal electrode is classified as monopolar. This designation refers to the use of a single electrode to deliver radiofrequency energy, which produces a continuous lesion in the targeted tissue. The monopolar technique contrasts with bipolar techniques, where two electrodes are used to create lesions by passing current between them, often leading to more localized effects. By employing a monopolar layout, the Simplicity procedure is able to achieve a larger and more uniform lesion, which is particularly important for effectively disrupting the electrical signals causing arrhythmias. This approach enhances the overall efficiency and effectiveness of the procedure, distinguishing it as the correct option in this context.
