CMR unmasks a right ventricular embolic infarction pattern in MINOCA
摘要
Myocardial infarction with non-obstructive coronary arteries (MINOCA) requires advanced imaging for etiological clarification. In a 76-year-old man initially suspected of myocarditis, cardiovascular magnetic resonance (CMR) revealed right ventricular and inferoseptal embolic myocardial infarction with microvascular obstruction (MVO). Subsequent detection of paroxysmal atrial fibrillation supported coronary embolism as the underlying mechanism, directly impacting diagnosis and management.
