Usefulness of Subepicardial Hyperemia on Contrast-Enhanced First-Pass Magnetic Resonance Perfusion Imaging for Diagnosis of Acute Myocarditis.

Hyperemia is a major criterion for the diagnosis of acute myocarditis on cardiac magnetic resonance imaging but its assessment is challenging and time consuming. We evaluated the usefulness of the contrast-enhanced first-pass perfusion (FPP) on magnetic resonance imaging for detecting subepicardial hyperemia in acute myocarditis. Forty-seven consecutive patients (mean age: 42 ± 15.

Prognostic value of the infarct- and non-infarct like patterns and cardiovascular magnetic resonance parameters on long-term outcome of patients after acute myocarditis.

Background: Prognostic value of the infarct- and non-infarct like patterns and cardiac magnetic resonance (CMR) parameters on long-term outcome of patients after acute myocarditis is not well known.

Methods: Between 2006 and 2015, 112 consecutive patients with CMR-based diagnosis of acute myocarditis were identified in our institution. Of them, 88 were available for clinical follow-up and represented our studied population.
