Introduction: The platypnea-orthodeoxia syndrome is a rare situation characterized by the appearance of dyspnea and/or hypoxemia during the transition to orthostatism. Observations: We report the case of two patients, who presented with a platypnea-orthodeoxia syndrome following pneumocystis pneumonia and COVID-19, revealing an intracardiac communication with a right-left shunt on contrast ultrasound. Conclusion: This syndrome can be detected easily at the bedside with positional maneuvers and the shunt demonstrated by a hyperoxia test. Non-reversible situations may require correction of the anatomical anomaly by transcatheter intervention or surgery.
