[Non-ischemic ventricular dysfunction in COVID-19 patients: characteristics and implications for cardiac imaging on the basis of current evidence]

Coronavirus 2019 disease (COVID-19), caused by SARS-CoV-2, can lead to cardiac impairment with various types of clinical manifestations, including heart failure and cardiogenic shock. A possible expression of cardiac impairment is non-ischemic ventricular dysfunction, which can be related to different pathological conditions, such as myocarditis, stress and cytokine-related ventricular dysfunction. The diagnosis of these pathological conditions can be challenging during COVID-19; furthermore, their prevalence and prognostic significance have not been elucidated yet. The purpose of this review is to take stock of the various aspects of non-ischemic ventricular dysfunction that may occur during COVID-19 and of the diagnostic implications related to the use of cardiac imaging techniques.
