Very late-onset atrial lead perforation leading to pneumopericardium

BackgroundAtrial lead perforation may lead to pneumopericardium or pneumothorax within a few days of device implantation. Methods and ResultsWe report a case of atrial lead perforation 6 years after cardiac resynchronization therapy implantation, which resulted in pneumopericardium and pneumothorax. ConclusionAlthough 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.
