Brief Summary

As of March 2020, COVID-19 has become a global pandemic, halting athletic competition worldwide.

Reports from China show a high prevalence of cardiac involvement in patients with severe SARS-CoV-2 infection. These cardiac forms were found to be closely associated with adverse outcomes. The use of Magnetic resonance Imaging (MRI) had allowed to show that cardiac dysfunction could be mediated by myocardial inflammation (i.e. myocarditis). The direct implication of the virus was demonstrated with Severe Acute Respiratory Syndrome (SARS)-CoV-2 being detected on myocardial biopsies in a patient with severe heart failure.

The experience with other viruses causing acute myocarditis shows that there is a high rate of undetected injuries. Indeed, although severe heart failure can be present at the acute stage, acute viral myocarditis is most commonly pauci or asymptomatic, but still leaving occult myocardial scars visible on MRI, and exposing to higher risks of ventricular arrhythmia and sudden cardiac death over the long term.

Although athletes are younger and have fewer comorbidities than the general population and therefore are at lower risk for severe disease or death, there is a critical and urgent need to assess the prevalence of occult scars in the population of high-level athletes returning to training after the SARS-CoV-2 pandemia.

Secondary Outcome Measures
NameTimeMethod
Presence of myocardial fibrosis by injected MRIMonth 3

In order to compare the prevalence of myocardial fibrosis between COVID-19 positive and COVID-19 negative individuals in high level athletes with or without rhythmic risk, a high resolution MRI is performed. The examinations is performed on 1.5 or 3T MRI systems equipped with specific antennas for cardiology. The sequence used to detect occult scars is a late enhancement sequence performed at least 15 minutes after injection of gadolinium salts, using a free-breathing 3D method, for a minimum spatial resolution of 2.5x1.25x1.25mm. The images are reviewed by a core lab at the Bordeaux University Hospital. The presence or absence of myocardial fibrosis is evaluated.
