“…There are documented cases of cardiac myxoma causing multiple embolic events. Rofle and colleagues described a case of a 37-year-old man with myocardial infarction and stroke, whereas Jawaid and colleagues described a 48-year-old man with an acute ischaemic stroke and right lower limb claudication 9 10…”

Ischaemic cerebral infarct is the most common neurological manifestation of myxomas. We present a mid-70s man who was brought to the stroke unit with sudden onset right hemiparesis and dysarthria. Although he had risk factors for developing stroke like hypertension, hypercholesterolaemia, history of prostate cancer and new paroxysmal atrial flutter on admission, clinical suspicion and detailed investigations in the absence of cardiac symptoms revealed a 9 cm myxoma causing severe mitral stenosis. He underwent successful surgical resection with good functional recovery. This also highlights the need for thorough clinical examination especially in the absence of cardiac symptoms.

Aims Explore the diagnostic value of multimodal imaging in identifying considerably rare causes of myocardial infarction. Methods and results We report a case of myocardial infarction with non-obstructive coronary arteries (MINOCA) probably due to coronary embolism associated with a left atrial myxoma. A 56-year-old male presented with non-ST-elevation myocardial infarction, with coronary angiography showing mild coronary atherosclerosis without significant epicardial stenosis. Transthoracic echocardiography and cardiac magnetic resonance imaging (CMR) revealed a large left atrial mass, suspected to be an atrial myxoma. CMR also showed an ischaemic pattern involving multiple coronary territories, suggesting coronary embolism as the cause of the MINOCA. The patient underwent successful surgical excision of the left atrial mass, and histopathology confirmed the diagnosis of cardiac myxoma. Conclusions This case highlights the relevance of CMR in detecting ischaemic patterns in patients with a working diagnosis of MINOCA and underlines the diagnostic value of multimodal imaging in identifying considerably rare causes of myocardial infarction, such as myxoma-associated coronary embolism.
