Patients were categorized into two groups based on the implantation technique: delivery catheter (\n                      <jats:italic>n<\/jats:italic>\n                      = 7) or stylet system (\n                      <jats:italic>n<\/jats:italic>\n                      = 30). Myocardial current of injury (COI) monitoring was used in the delivery catheter group to guide lead fixation. The lead position was assessed by cardiac computed tomography, and procedural outcomes were compared.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Accurate RV septal lead placement was achieved in 100% of the delivery catheter group compared to 60% in the stylet group (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.047). The delivery catheter group also demonstrated significantly shorter lead implantation time (median 9 vs. 17 min,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.016) and total fluoroscopy time (median 15 vs. 29 min,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.009). Lead parameters and complication rates were comparable. A subclinical pericardial effusion was identified in one patient from the stylet group, in whom the lead was positioned in the RV free wall.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The use of the delivery catheter with COI monitoring significantly enhanced the accuracy and efficiency of RV septal defibrillator lead implantation without compromising safety.
