Cardiac Magnetic Resonance Imaging in Lyme Carditis-A Case Series and Review of Literature.

Lyme carditis is an uncommon but potentially fatal manifestation of early disseminated Lyme disease. Timely diagnosis poses a clinical challenge due to the highly variable and non-specific symptomatology that can be easily overlooked, as well as the limited availability of specific and non-invasive diagnostic tests for assessing cardiac involvement. While cardiac magnetic resonance (CMR) imaging is the standard imaging modality for diagnosing various etiologies of cardiomyopathy, its application in Lyme carditis remains understudied. In this study, we present two cases of CMR-proven Lyme carditis and provide a comprehensive review of the existing literature on the use of CMR in this condition.
