Very late-onset atrial lead perforation leading to pneumopericardium.

BACKGROUND

Atrial lead perforation may lead to pneumopericardium or pneumothorax within a few days of device implantation.

METHODS AND

RESULTS

We report a case of atrial lead perforation 6 years after cardiac resynchronization therapy implantation, which resulted in pneumopericardium and pneumothorax.

CONCLUSION

Although pneumopericardium caused by atrial lead perforation can spontaneously resolve with conservative treatment, as it did in this case, treatment should be decided based on the patient's general condition and lead performance.
