In this report we describe the clinical presentation, laboratory
findings and outcomes of four patients that were referred for urgent
cardiothoracic intervention and tested positive for COVID-19. Though the
majority of the patients undergoing surgery had low Society of Thoracic
Surgeons score and uneventful operating time, mortality was very high
and driven primarily by the viral syndrome. Laboratory markers that have
been associated with disease severity in the general population were
also prognostic in our population. Our study shows that these patients
have very high mortality, whereas prevention and preoperative screening
is required in preventing nosocomial spreading of the disease.
