A unique case report of relapsing eosinophilic myocarditis causing atrial myopathy and persistent sinus arrest.

ABSTRACT:

Background

Eosinophilic myocarditis (EM) is a rare and devastating condition. The underlying cause of EM is unknown, and the natural history is not well understood.

Case summary

A 20-year-old male presented in cardiogenic shock with preceding 24-h history of pleuritic chest pain associated with nausea and vomiting. Electrocardiogram showed sinus tachycardia with widespread ST elevation, significantly raised high-sensitivity troponin T, and raised white cell count with eosinophilia. Transthoracic echocardiogram demonstrated severe left ventricular (LV) impairment and a moderate-sized pericardial effusion. Right ventricular (RV) endomyocardial biopsy and bone marrow biopsy were performed, with both demonstrating prominent eosinophilia. He was initiated on pulse methylprednisol
