Key result
Intracoronary imaging (OCT, IVUS) and cardiac magnetic resonance imaging provide significant diagnostic and prognostic value in identifying the underlying pathology of MINOCA.
Why the study?
To summarize scientific statements on MINOCA diagnosis and management, define the diagnostic roles of OCT, IVUS, and CMR, and provide representative case examples.
Does the use of advanced imaging (OCT, IVUS, CMR) improve the diagnosis of underlying pathology in patients with MINOCA compared to conventional angiography?
Does the use of advanced imaging (OCT, IVUS, CMR) improve the diagnosis of underlying pathology in patients with MINOCA compared to conventional angiography?
The routine use of intracoronary imaging and CMR is crucial for accurately diagnosing the underlying etiology of MINOCA, allowing for tailored management and improved prognostication.
May aid etiology-specific management in MINOCA; leaves open prospective validation before routine adoption.
Purpose of Review The objective of this review is to summarize scientific statements on the diagnosis and management of myocardial infarction with no obstructive coronary artery disease (MINOCA); define the diagnostic role of optical coherence tomography (OCT), intravascular ultrasound (IVUS), and cardiac magnetic resonance imaging (CMR); and provide representative case examples. Recent Findings The majority of patients with MINOCA are evaluated by conventional coronary angiography. However, intracoronary imaging using OCT or IVUS permits more accurate understanding of the underlying pathology. These and other imaging modalities provide significant diagnostic and prognostic value. Summary Although nonobstructive disease is the hallmark of the disease, MINOCA is associated with significant morbidity and mortality. Every effort to define the underlying pathology is necessary and requires more standardized use of imaging in clinical practice.

Alasnag et al. (2020) conducted a review in Myocardial Infarction with No Obstructive Coronary Artery Disease (MINOCA). Intracoronary imaging (OCT, IVUS) and Cardiac Magnetic Resonance (CMR) vs. Conventional coronary angiography was evaluated. Intracoronary imaging (OCT, IVUS) and cardiac magnetic resonance imaging provide significant diagnostic and prognostic value in identifying the underlying pathology of MINOCA.
