ABSTRACT

Platypnea-orthodeoxia syndrome (POS) is a clinical entity characterized by positional dyspnoea (platypnea) and arterial desaturation (orthodeoxia) that occurs when sitting or standing up and usually resolves by lying down. POS may result from some cardiopulmonary disorders or from other miscellaneous aetiologies. We report a case of POS in a patient after fibrotic evolution of SARS-CoV-2 interstitial pneumonia associated with pulmonary embolism. The patient did not have any evidence of an intracardiac/intrapulmonary shunt.

ABSTRACT

Platypnea-orthodeoxia syndrome, characterized by dyspnoea and arterial desaturation while upright, is a rare complication of acute respiratory distress syndrome. We report here 2 patients with COVID-19 pneumonia, who were diagnosed with platypnea-orthodeoxia syndrome during commencement of rehabilitation, 18 and 9 days respectively after admission to the intensive care unit. Both patients presented with normocapnic hypoxaemia. One patient required mechanical ventilation with supplemental oxygen during intensive care, while the other required high-flow nasal oxygen therapy. The manifestations of platypnea-orthodeoxia syndrome were most prominent during physiotherapy, when verticalization was attempted, and hindered further mobilization out of bed, including ambulation. This report describes the clinical manifestations of platypnea-orthodeoxia syndrome and the rehabilitative strategies carried out for these 2 patients. The platypnea-orthodeoxia syndrome in these patients resolved after 65 and 22 days respectively from the day of detection. This report highlights this potentially under-recognized phenomenon, which may be unmasked during rehabilitation of patients with COVID-19 pneumonia. Good functional outcomes were achieved with a combination of verticalization training with supplemental oxygen support, respiratory techniques training and progressive endurance and resistance training, whilst awaiting resolution of the platypneaorthodeoxia syndrome.

ABSTRACT

BACKGROUND: Platypnea-orthodeoxia syndrome (POS) is a rare condition characterized by dyspnoea (platypnea) and arterial desaturation in the upright position resolved in the supine position (orthodeoxia). Intracardiac shunt, pulmonary ventilation-perfusion mismatch and others intrapulmonary abnormalities are involved. CASE PRESENTATION: We report a case of POS associated with two pathophysiological issues: one, cardiac POS caused by a patent foramen ovale (PFO) and second, pulmonary POS due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interstitial pneumonia. POS has resolved after recovery of coronavirus disease 2019 (COVID-19) pneumonia. CONCLUSIONS: Right-to-left interatrial shunt and intrapulmonary shunt caused by SARS-CoV-2 pneumonia contributed to refractory hypoxemia and POS. Therefore, in case of COVID-19 patient with unexplained POS, the existence of PFO must be investigated.
