This study aimed to evaluate whether systematic AECG monitoring after TAVR reduces life-threatening cardiovascular events during the first year of follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>The study included 1217 consecutive patients who underwent TAVR and were discharged without a permanent pacemaker. Of these, 211 consecutive patients received systematic 14-day AECG monitoring at discharge as part of the RECORD (Assessment of Arrhythmic Burden With Post-Procedural Continuous Electrocardiographic Monitoring in Patients Undergoing Transcatheter Aortic Valve Implantation) registry. The remaining 1006 patients who underwent TAVR within the 3 years before and after the registry period without systematic AECG monitoring constituted the control group. The primary end point was a composite of sudden cardiac death, syncope\/presyncope due to symptomatic arrhythmias, or stroke at 1-year.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Baseline and procedural characteristics were similar between groups, except for a higher use of self-expandable valves in the control group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.005). Systematic AECG monitoring was associated with a lower incidence of the primary endpoint (1.9% versus 6.6%; adjusted hazard ratio, 0.27 [0.10\u20130.74];\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.011), mainly driven by a lower rate of sudden death or arrhythmic syncope\/presyncope (0.9% versus 4.0%; adjusted hazard ratio, 0.22 [0.05\u20130.89];\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.034).
