Key result
Cardiac MRI anchors acute myocarditis diagnosis by detecting abnormalities defining the Lake Louise criteria.
Why the study?
Acute myocarditis presents with great clinical diversity, making diagnosis challenging and reliant on detecting myocardial tissue abnormalities via modalities such as cardiac MRI.
What is the role of cardiac magnetic resonance imaging in the diagnosis of acute myocarditis?
What is the role of cardiac magnetic resonance imaging in the diagnosis of acute myocarditis?
This educational review highlights the critical role of cardiac MRI and the Lake Louise criteria in diagnosing acute myocarditis.
Reinforces cardiac MRI with Lake Louise criteria for acute myocarditis diagnosis; leaves open need for prospective validation in modern cohorts.
Acute myocarditis represents one of the most mysterious acute cardiovascular diseases due to the great diversity of its clinical presentation, ranging from simple symptoms such as flu-like syndrome to lethal conditions such as cardiogenic shock or sudden cardiac death. The diagnosis will be suspicious in the presence of chest pain in a subject with risk factors, and guided mainly by the ECG, biological markers, trans-thoracic echocardiography, and the cardiac MRI. In this sense, and returning to the pathophysiological bases of this condition, the positive diagnosis will rely mainly on the detection of tissue abnormalities secondary to the myocardial inflammatory storm. Cardiac MRI represents a diagnostic pillar, given the information it can provide, both in analyzing the morphology, and the myocardial function but also tissue abnormalities that represent the main element of the diagnostic criteria of Lake Louisse.

Joudar et al. (2023) conducted a review in Acute myocarditis. Cardiac magnetic resonance imaging was evaluated. Cardiac MRI serves as a diagnostic pillar for acute myocarditis by detecting morphological, functional, and tissue abnormalities that form the basis of the Lake Louise criteria.
