INTRODUCTIONWith the spread of the use of implantable loop recorders (ILRs) by cardiologists for outpatient cardiac monitoring, intrathoracic migration represents a rare but possible complication occurring after the placement of these devices. Very few cases of ILRs intrathoracic migration into the pleural cavity have been reported, followed in even fewer cases by surgical removal of the devices, but in none re-implantation was performed. PRESENTATION OF CASEWe report the first case of a patient with a new generation ILR accidentally migrated into the postero-inferior costophrenic recess of the left pleural cavity, successfully removed by uniportal video-assisted thoracic surgery (VATS) and submitted to re-implantation of a new ILR in the same operating session. DISCUSSIONTo reduce the risk of ILRs intrathoracic displacement, the insertion technique must be performed in the most suitable part of the chest wall, with the correct incision and angle of penetration, by an expert operator. When migrated into the pleural cavity, surgical removal should be performed to avoid the onset of early and late complications. A mini-invasive surgical approach by uniportal VATS could be considered as the first choice, ensuring a favourable patient outcome. Re-implantation of a new ILR can be safely performed in the same operating session. CONCLUSIONIn case of intrathoracic migration of ILRs, early removal by mini-invasive approach is recommended as well as concomitant re-implantation. Beyond periodic monitoring of ILRs by cardiologists, strict radiological follow-up with chest X-ray is advisable after implantation, in order to early identify any abnormalities and correctly manage them.
