Left and right ventricular morphology, function and late gadolinium enhancement extent and localization change with different clinical presentation of acute myocarditis Data from the ITAlian multicenter study on MYocarditis (ITAMY)

543 in-patients with clinically suspected acute myocarditis confirmed by CMR. Indications included chest pain, dyspnea, palpitations, effort intolerance, elevated troponin, new ventricular dysfunction, new ECG abnormalities, and suspected inflammatory cause.
