During an atrial fibrillation ablation, a clot occurred which resulted in the cancellation of the procedure.In addition, there were communication issues with the amplifier.When the ablation catheter was inserted, it was unstable.Breathing was compensated but the catheter continued to oscillate more than usual.The amplifier was reconnected and restarted, but the issue persisted.Then the computer was restarted, and a new map was completed with the mapping catheter.A clot was then detected, so the procedure was suspended at that time.A transesophageal echocardiography was done prior to the procedure and there were no clots noted at that time.Due to the issue, the ablation catheter was not re-introduced into the patient, and it was not verified whether the issue persisted after restarting the computer.There was no intervention needed to treat the clot found during the procedure.
