Post-ACS death, myocardial infarction, stroke, and overall major adverse cardiovascular or cerebrovascular events were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The ACS clinical presentation consisted of non\u2013ST-segment\u2013elevation myocardial infarction (STEMI) type 2 (31.9%), non\u2013STEMI type 1 (31.5%), unstable angina (28.5%), and STEMI (8.1%). An invasive strategy was used in 163 patients (60.4%), and a percutaneous coronary intervention was performed in 97 patients (35.9%). Coronary access issues were observed in 2.5% and 2.1% of coronary angiography and percutaneous coronary intervention procedures, respectively. The in-hospital mortality rate was 10.0%, and at a median follow-up of 17 (interquartile range, 5\u201332) months, the rates of death, stroke, myocardial infarction, and major adverse cardiovascular or cerebrovascular events were 43.0%, 4.1%, 15.2%, and 52.6%, respectively. By multivariable analysis, revascularization at ACS time was associated with a reduction of the risk of all-cause death (hazard ratio, 0.54 [95% CI, 0.36\u20130.81]\n                      <jats:italic>P<\/jats:italic>\n                      =0.003), whereas STEMI increased the risk of all-cause death (hazard ratio, 2.06 [95% CI, 1.05\u20134.03]\n                      <jats:italic>P<\/jats:italic>\n                      =0.036) and major adverse cardiovascular or cerebrovascular events (hazard ratio, 1.97 [95% CI, 1.08\u20133.57]\n                      <jats:italic>P<\/jats:italic>\n                      =0.026).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>ACS events in TAVR recipients exhibited specific characteristics (ACS presentation, low use of invasive procedures, coronary access issues) and were associated with a poor prognosis, with a very high in-hospital and late death rate. STEMI and the lack of coronary revascularization determined an increased risk. These results should inform future studies to improve both the prevention and management of ACS post-TAVR.<\/jats:p>\n
