Abstract
In an ever-changing information flow on coronavirus disease 2019 (COVID-19) pandemic, we describe a case series of mitral valve chordal rupture (MVCR) in non-comorbid middle-aged men that occurred over a period of 3 to 5 weeks after Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) infection. With significant advances in the prevention of acute rheumatic fever, the treatment of bacterial endocarditis and acute coronary syndrome, acute mitral regurgitation has become a relatively rare diagnosis. During the pandemic, there has been a surge in the incidence of spontaneous MVCR, and new data on the problem are accumulating. The presented case series are united by the fact that the infection symptoms were mild, followed by signs of probable endomyocarditis, unrecognized in time, and acute mitral valve regurgitation developed against the background of physical provocation (exercise and cough). Two patients had previously been diagnosed with mitral valve prolapse (myxomatous degeneration and connective tissue disease). Two patients were successfully operated on in different clinics. The described cases emphasize that the consequences of inflammation persistence may be more severe than the primary viral damage, which determines the importance of a comprehensive examination and long-term follow-up. To date, the differential diagnosis of patients with sudden onset of dyspnea and chest pain associated with an infectious process should include MVCR.
