Right-to-Left Intra-cardiac Shunt in a COVID-19 Patient Leading to Stroke and Poor Prognosis: A Case Report and Review of the Literature.

Coronavirus disease 2019 (COVID-19) often presents with a wide range of complications, including respiratory distress, acute respiratory distress syndrome (ARDS), and hypercoagulable states with resultant cerebrovascular incidents. Intra- and extra-pulmonological shunts can further complicate patient courses, leading to persistent hypoxemia and paradoxical emboli, resulting in potentially life-threatening consequences, necessitating a comprehensive, multidisciplinary approach to patient care. Here we present the case of a 73-year-old male who experienced severe persistent hypoxemic respiratory failure, superimposed methicillin-resistant  Staphylococcus aureus (MRSA) pneumonia, and stroke with a previously undiagnosed patent foramen ovale (PFO) contributing to his clinical presentation.
