Platypnea-orthodeoxia syndrome (POS) causes shortness of breath when standing. Diagnosis can be challenging, but two case studies highlight effective management strategies for this rare condition.
Area of Science:
- Cardiology
- Pulmonology
- Medical Diagnostics
Background:
- Platypnea-orthodeoxia syndrome (POS) is a rare condition characterized by positional dyspnea and hypoxemia.
- It is often linked to right-to-left shunting via a patent foramen ovale or atrial septal defect, though its pathophysiology is not fully understood.
- POS is frequently underdiagnosed due to its uncommon nature.
