The major requirement for optimal echocardiographic image interpretation, reproducibility, and diagnostic accuracy is image quality. Despite the use of harmonics, a significant proportion of patients have challenging images, which has an impact on diagnosis and management. The ultrasound contrast agents (UCAs), which are administered intravenously, have been a significant development in image quality optimization and have proved to be an important aid in the assessment of structural abnormalities, detection of regional wall motion abnormalities, and calculation of left ventricular ejection fraction. The use of UCAs is also of critical importance for the detection of ischaemia and the assessment of significant coronary artery disease through detection of inducible regional wall motion abnormalities during stress echocardiography. UCAs can also assess myocardial perfusion, which improves assessment of myocardial ischaemia during stress echocardiography. Similarly the simultaneous assessment of wall motion and perfusion improves assessment of viable myocardium in patients with left ventricular dysfunction. As the use of UCAs results in increased feasibility, reproducibility, and diagnostic and prognostic accuracy of echocardiography including cost-efficiency, both European and American guidelines endorse its use in clinical cardiology.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a syndrome with different causes, characterised by clinical evidence of myocardial infarction with normal or near-normal coronary arteries on angiography. Its prevalence ranges between 5% and 25% of all myocardial infarction. The prognosis is extremely variable, depending on the cause of MINOCA. The key principle in the management of this syndrome is to clarify the underlying individual mechanisms to achieve patient-specific treatments. Clinical history, electrocardiogram, cardiac enzymes, echocardiography, coronary angiography and left ventricular angiography represent the first level diagnostic investigations to identify the causes of MINOCA. Regional wall motion abnormalities at left ventricular angiography limited to a single epicardial coronary artery territory identify an ‘epicardial pattern’whereas regional wall motion abnormalities extended beyond a single epicardial coronary artery territory identify a ‘microvascular pattern’. The most common causes of MINOCA are represented by coronary plaque disease, coronary dissection, coronary artery spasm, coronary microvascular spasm, Takotsubo cardiomyopathy, myocarditis, coronary thromboembolism, other forms of type 2 myocardial infarction and MINOCA of uncertain aetiology. This review aims at summarising the diagnosis and management of MINOCA, according to the underlying physiopathology.
