The worldwide spread of the severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) has created unprecedented situations for healthcare professionals and healthcare systems. Although infection with this virus is considered the main health problem currently, other diseases are still prevalent.
CASE REPORT: This report describes a 59-year-old man who presented with symptoms of dyspnea and fever that were attributed to Covid-19 infection. His clinical condition deteriorated and further examinations revealed a subjacent severe aortic regurgitation due to acute infective endocarditis. Surgical treatment was successful.
CONCLUSIONS: The results of diagnostic tests for Covid-19 should be re-evaluated whenever there are clinical mismatches or doubts, as false-positive Covid-19 test results can occur. Clinical interpretation should not be determined exclusively by the Covid-19 pandemic. This case report highlights the importance of using validated and approved serological and molecular testing to detect infection with SARS-CoV-2, and to repeat tests when there is doubt about presenting symptoms.
