Temporary mechanical circulatory support (tMCS) devices are increasingly used to maintain end\u2010organ perfusion during VT ablation, yet their impact on clinical outcomes remains uncertain. We aimed to evaluate the impact of tMCS on clinical outcomes and periprocedural complications in patients undergoing VT ablation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:label\/>\n                    <jats:p>A systematic search of PubMed\/MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL was conducted from database inception through December 2025. We included observational studies enrolling adult patients undergoing VT ablation with tMCS, compared with VT ablation performed without MCS. Primary outcomes were all\u2010cause mortality, in\u2010hospital mortality, procedural success, VT recurrence, and major adverse cardiovascular events (MACE).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:label\/>\n                    <jats:p>Ten observational studies comprising 16,838 patients were included, of whom 1402 received tMCS. There was no significant difference in all\u2010cause mortality between tMCS and no\u2010MCS groups (RR 1.71, 95% CI 0.68 to 4.26), procedural success (RR 1.05, 95% CI 0.92 to 1.21), VT recurrence (RR 0.99, 95% CI 0.80 to 1.22), or MACE (RR\u2009=\u20090.79, 95% CI: 0.62 to 1.01). However, tMCS use was associated with significantly higher in\u2010hospital mortality (RR 7.41, 95% CI 4.77 to 11.66). The tMCS group also demonstrated increased risks of stroke, pericardial effusion or tamponade, and periprocedural complications.<\/jats:p>\n                  <\/jats:sec>\n
