Key result
Multimodality imaging, including intravascular ultrasound, optical coherence tomography, and cardiovascular magnetic resonance, aids in diagnosing and evaluating patients with MINOCA.
Why the study?
MINOCA defines a heterogeneous group of conditions where unveiling the mechanisms underlying the acute event is often challenging, making a multimodality imaging approach helpful.
A multimodality imaging approach, utilizing invasive techniques like IVUS/OCT and non-invasive CMR, is crucial for identifying the underlying mechanisms and differentiating MINOCA from non-ischemic mimics.
Multimodality imaging may aid MINOCA differentiation; leaves open prospective trials before routine adoption.
Myocardial infarction with non-obstructive coronary arteries (MINOCA) defines a heterogeneous group of atherosclerotic and non-atherosclerotic conditions, causing myocardial injury in the absence of obstructive coronary artery disease. Unveiling the mechanisms subtended to the acute event is often challenging; a multimodality imaging approach is helpful to aid the diagnosis. Invasive coronary imaging with intravascular ultrasound or optical coherence tomography should be used, when available, during index angiography to detect plaque disruption or spontaneous coronary artery dissection. Cardiovascular magnetic resonance has instead a key role among the non-invasive modalities, allowing the differentiation between MINOCA and its non-ischaemic mimics and providing prognostic information. This educational paper will provide a comprehensive review of the strengths and limitations of each imaging modality in the evaluation of patients with a working diagnosis of MINOCA.
