ABSTRACT
El uso de la Resonancia Magnética Cardiaca (RMC), se ha convertido en los últimos años en una herramienta fundamental para el diagnóstico de diversas miocardiopatías, entre las cuales sobresale la miocarditis, entidad que cursa con manifestaciones y signos clínicos muy variables y poco específicos en la mayor parte de los casos, lo que la convierte en una patología difícil de reconocer sobre todo en sus episodios de presentación inicial, lo que probablemente conlleve a que sea subdiagnosticada. El desarrollo de nuevas modalidades de imagen ha permitido que ante la sospecha de esta entidad el uso de la RMC se convierta en la técnica ideal para el diagnóstico temprano. A continuación se presenta el caso clínico de un paciente masculino que acude con cuadro de dolor torácico agudo, enzimas cardiacas elevadas, electrocardiograma no concluyente y coronarias normales, mostrando el curso insidioso de esta patología así como de manera resumida el rol de la RMC en su diagnóstico y pronóstico.
The use of cardiac magnetic resonance (CMR) has become in recent years an essential tool for diagnosing various cardiomyopathies, among which stands myocarditis, an entity that presents with demonstrations and highly variable clinical signs and unspecific in most cases, which makes it a difficult disease to recognize especially in its initial filing episodes, which probably lead to be underdiagnosed. The development of new imaging modalities has allowed suspicion of this entity using the RMC becomes the ideal technique for early diagnosis. Next, the case of a male patient presenting with symptoms of acute chest pain, elevated cardiac enzymes inconclusive electrocardiogram and normal coronary showing insidious course of this disease and in summary the role of the RMC in its presented diagnosis and prognosis.

IMPORTANCE: Systemic diseases that affect the cardiovascular system constitute a diagnostic and therapeutic challenge for all specialists involved; imaging tools along with clinical suspicion play an essential role in their evaluation. These entities share neurological, immunological, renal, hematologic, oncologic, infectious and endocrine processes, all of which may have associated cardiac involvement. OBSERVATIONS: Recent advances in cardiac ultrasound, Computed Tomography (CT), cardiac Magnetic Resonance (CMR) and nuclear scintigraphy have impacted the management of these conditions when involving the heart since they provide valuable anatomical and functional information while avoiding the use of invasive techniques. For this review, bibliographic sources were gathered from diverse databases, including PubMed, Cochrane, EBSCO and Google Scholar, concentrating on English language publications dealing with the clinical use of these tools. CONCLUSION: Clinical suspicion should always guide the use of imaging since in many instances, these techniques only play a supportive role rather than representing a diagnostic gold standard. Early diagnosis is critical due to the fact that cardiac manifestations are commonly a late phenomenon.
