“…At the level of the myocardium, the lesions were preferentially located subepicardial 90% and/or intramural 30%, never subendocardial. Our result was identical to that of Paule et al who reported one or more foci of late subepicardial and/or intramyocardial enhancement in 90% of patients [12]. These results are in line with the data in the literature by constituting a reliable argument in favor of the diagnosis of acute myocarditis and helping to rule out an Acute Coronary Syndrome (ACS) [9].…”

Objective: To describe the MRI abnormalities observed in acute myocarditis. Materials and Methods: Retrospective cross-sectional study with a descriptive aim, carried out at the North Franche-Comte Hospital, over a period of 12 months, from January 2021 to December 2021. It covered all patients who received an MRI of heart disease and were diagnosed with myocarditis. The diagnosis of myocarditis was retained in all patients on the basis of two arguments: a T2 PSIR hyper signal and a late enhancement at 15 min in T1 PSIR with gadolinium. Results: Myocarditis was diagnosed in 20 patients out of a total of 214 who performed cardiac MRI, i.e. 10.30% of cases. The average age was 33.7 ± 14.3 with extremes of 17 and 69 years. We observed a male predominance with 11 men (55%) for 9 women (45%) or a sex ratio of 1.2. Clinical suspicion of myocarditis and acute coronary syndrome were the main indications for MRI. The lesion sites were subepicardial (95%) and/or intramural (30%), respecting the subendocardium, interesting for the majority, segments 12 (anterolateral) in 50% and/or 11 (inferolateral) in 43% of cases. Global hypokinesia was observed in 30% of patients associated with a decrease in LVEF. There was no cardiac volume abnormality or valvular abnormality. Conclusion: Cardiac MRI is nowadays the most efficient non-invasive imaging in the diagnosis of acute myocarditis. The diagnosis of myocarditis was made on

“…Ces patients nécessitent de surcroît une surveillance à court et moyen termes de la fonction ventriculaire gauche. Les données de la littérature restent assez incertaines en matière d'histoire naturelle de ces myocardites aiguës d'allure initialement bénignes; il est très vraisemblable que la grande majorité d'entre elles guérissent sans séquelles; certaines détériorations retardées de la fonction ventriculaire gauche semblent néanmoins possibles, méritant donc une surveillance (échographique et ou IRM) renouvelée à échéance par exemple de 3 mois, 6 mois puis annuelle pendant 2 ou 3 ans [ 8 ].…”

Le diagnostic de myopéricardite aiguë est difficile surtout quand la présentation clinique mime un syndrome coronaire aiguë. Nous rapportons l'observation d'un patient âgé de 40 ans admis pour un syndrome coronarien aiguë ST+ chez qui la coronarographie réalisée en urgence montre un réseau coronaire angio-graphiquement sain. L'imagerie par résonance magnétique (IRM) permettra d'affirmer le diagnostic d'une myopéricardite. Cette observation confirme le rôle primordial de l'IRM cardiaque chez les patients présentant une suspicion clinique de myocardite aiguë ou un tableau de SCA à coronaire saines.

“…Nos últimos anos, alguns autores tentaram identificar achados na RMC em pacientes com MPA que estivessem relacionados ao prognóstico [17][18][19][20][21][22] O diagnóstico clínico da MPA idiopática foi estabelecido em pacientes com dor torácica e critérios de pericardite aguda com elevação de marcadores de lesão miocárdica (troponina I acima do percentil 99%) 23 . Todos os pacientes foram submetidos à realização de cineangiocoronariografia ou angiotomografia de coronárias, demonstrando não haver lesões obstrutivas coronarianas (lesões < 50% do diâmetro luminal do vaso).…”
