FEATURED CLINICAL CASE Platypnoea–orthodeoxia syndrome
Platypnoea–orthodeoxia is a rare syndrome of postural hypoxaemia accompanied by breathlessness. The predominant symptom, dyspnoea induced by upright posture, can be debilitating and diYcult to discern without thorough evaluation of the patient’s pattern of dyspnoea. The precise cause of the syndrome is unclear but patients develop right to left intracardiac shunting in the presence of normal ri...
متن کاملReversible platypnoea–orthodeoxia syndrome in post‐tuberculosis bronchial stenosis
Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea-orthodeoxia syndrome in a young woman with acute atelectasis due to post-tuberculo...
متن کاملDynamic echocardiography in evaluation of platypnoea‐orthodeoxia
Platypnoea-orthodeoxia is an infrequent syndrome that is usually associated with positional intracardiac right-to-left shunting. The authors report the case of a patient who presented with deteriorating severe dyspnoea and deoxygenation in the upright position that was partially relieved by recumbent repositioning. Dynamic echocardiography provided insight into the underlying anatomical and pat...
متن کاملPlatypnoea-orthodeoxia syndrome, an underdiagnosed cause of hypoxaemia: four cases and the possible underlying mechanisms
Cardiac platypnoea-orthodeoxia syndrome (POS) is a position-dependent condition of dyspnoea and hypoxaemia due to right-to-left shunting. It often remains unrecognised in clinical practice, possibly because of its complex underlying pathophysiology. We present four consecutive patients with POS and patent foramen ovale (PFO) who underwent a successful percutaneous PFO closure, describe the mech...
متن کاملPneumocystis carinii pneumonia with pleurisy, platypnoea and orthodeoxia.
We present a patient who collapsed with chest pain and dyspnoea on a transatlantic flight. She was found to have Pneumocystis carinii pneumonia (PCP) and human immunodeficiency virus infection. Platypnoea and orthodeoxia, which have not been previously reported in association with PCP, were major features of her illness. The PCP predominantly affected her lung bases and it is likely that gravit...
