We present the case of an asymptomatic S-ICD lead migration in a 38-years-old woman, previously implanted in 2013 (3 incision technique, subcutaneous pocket, secondary prevention) and subsequent need of MRI compatible device. During the new procedure, due to lack of the thoracic lead detection at previous scars we documented fluoroscopically its migration down and left lateral. The possibility of lead migration should be considered because an important alteration in its position could affect at first defibrillation threshold and only subsequently significant alterations in sensing values. A periodic chest X-rays compared to one performed post implantation might have a clinical role in addition to electronic follow-ups, especially before S-ICD replacement.
