While extraction is standard for infection, it is unclear whether transvenous lead extraction (TLE) or lead abandonment (LA) provides superior outcomes for superfluous leads. Prophylactic TLE may prevent future infection or venous obstruction and avoid complex delayed extraction but carries immediate procedural risk. Conversely, LA avoids upfront risk, though retained leads may predispose to long\u2010term sequelae.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To compare procedural and clinical outcomes of TLE versus LA for non\u2010infected leads and assess how pre\u2010existing abandoned leads influence the risks of subsequent extraction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>PubMed, Embase, OVID, and Cochrane were searched (2000\u20132025) for studies comparing TLE versus LA and TLE with versus without abandoned leads. Twenty\u2010three observational studies involving 65,760 patients were included. Data was extracted by two investigators using PRISMA guidelines. Primary outcomes included major complications, in\u2010hospital mortality, and clinical success, pooled as odds ratios with 95% confidence intervals using a random\u2010effects model. Subgroup and meta\u2010regression analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>TLE was associated with significantly higher odds of major complications (OR 2.07, 95% CI 1.42\u20133.03) and in\u2010hospital mortality (OR 2.97, 95% CI 1.95\u20134.53) compared with LA, with no significant long\u2010term difference within limited follow\u2010up. Extraction of previously abandoned leads carried higher risks of major complications (OR 2.51), minor complications (OR 1.79), and mortality (OR 2.06), with lower clinical success (OR 0.24) than functional leads.
