However, risk stratification for implantable cardioverter\u2010defibrillator implantation in this group is needed. We aimed to determine if electrophysiologic study (EPS) may be used as a noninvasive alternative for sudden cardiac death risk stratification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">In this retrospective cohort study, we analyzed patients with CS (aged &gt;18\u2009years) with highly probable or probable sarcoidosis according to the World Association of Sarcoidosis and Other Granulomatous Disorders Sarcoidosis Organ Assessment Instrument, with evidence of late gadolinium enhancement on cardiac magnetic resonance imaging in a pattern consistent with CS and left ventricular ejection fraction \u226540%, who underwent EPS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      We identified 101 patients with CS, 15 EPS positive and 86 EPS negative. A higher proportion of patients with an EPS\u2010positive study was associated with antiarrhythmic therapy (\n                      <jats:italic toggle=\"no\">P=<\/jats:italic>\n                      0.005) and ventricular tachycardia on ECG or Holter monitoring (\n                      <jats:italic toggle=\"no\">P&lt;<\/jats:italic>\n                      0.001). In multivariable analysis, transmural myocardial scarring (odds ratio, 3.78 [95% CI, 1.05\u201314];\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.041) and edema on T2\u2010weighted cardiac magnetic resonance imaging (odds ratio, 4.75 [95% CI, 1.09\u201321.2];\n                      <jats:italic toggle=\"no\">P=<\/jats:italic>\n                      0.036) were associated with higher odds of an EPS\u2010positive study. There was no association between anatomic distribution of scar within left ventricular and right ventricular segments and inducibility on EPS.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">In patients with CS and mildly impaired left ventricular ejection fraction, we demonstrated that transmural myocardial scarring and edema on T2\u2010weighted cardiac magnetic resonance imaging are associated with sustained ventricular arrhythmia during EPS, suggesting that noninvasive imaging features may be used as prognostic indicators in patients with CS. Larger, prospective studies are needed to inform implantable cardioverter\u2010defibrillator implantation guidelines.<\/jats:p>\n
