      Catheter ablation is an important therapeutic modality for the treatment of patients with atrial fibrillation (AF). Although it is a complex procedure that requires specific training, multiple advancements have occurred, including development of new technology to help reduce AF recurrence. Contact force (CF) technology has been recently adopted to enhance lesion formation by helping to ensure tissue contact and adequate lesion depth. Previously, surrogate measures such as a fall in impedance or rise in temperature were used to assess lesion quality, in addition to tactile sensation to help estimate catheter-tissue contact. CF-sensing catheters have been shown to result in a more durable effect of ablation lesions and lower AF recurrence rates (37% reduction during 12-month follow-up).
