Follow-up protocol
A home monitoring system (LATITUDETM NXT) was offered to all patients after device implantation. Patients were discharged on the second post-procedural day, as per standard ICD discharging practice in our country. As per our center outpatient clinic protocol, all patients were seen for an in-person standard device interrogation 1-month after discharge and every 6 months thereafter. At each follow-up visits, a clinical evaluation was performed, and patients were screened for appropriate/inappropriate shocks, infections, lead displacement and other adverse events. Complications were defined as device related events requiring medical or surgical intervention for resolution and/or device reprogramming.
