Case Report: Optical Pumped Magnetometer Magnetocardiography as a Potential Method of Therapy Monitoring in Fulminant Myocarditis

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Fulminant myocarditis (FM) is associated with high mortality and an unfavorable long-term prognosis. However, noninvasive, rapid diagnostic and monitoring methods for FM are lacking.

This article details the case of a patient diagnosed with FM through a comprehensive assessment involving typical clinical symptoms, laboratory analyses, echocardiographic evidence, and cardiac magnetic resonance (CMR) findings.

Before the patient underwent CMR, optical pumped magnetometer magnetocardiography (OPM-MCG) revealed abnormalities characteristic of substantial myocardial injury. After invasive coronary angiography, the patient’s coronary arteries were determined not to exhibit significant stenosis. Additionally, a myocardial bridge was observed in the middle segment of the anterior descending branch of the left coronary artery. Over a 7-month follow-up, the patient’s symptoms showed marked improvement, and the OPM-MCG eventually normalized, aligning with the findings indicated by the CMR.

OPM-MCG is a valuable tool for therapy monitoring in FMs, offering a safe, non-invasive, and highly effective test for ancillary diagnostics and long-term prognostic follow-up. Additionally, MCG may potentially assist in clinical decision-making regarding the need for further interventions in patients with myocardial bridge.
