Platypnea and orthodeoxia syndrome as an uncommon clinical indication for a challenging percutaneous patent foramen ovale closure: a case report.

ABSTRACT:

Background

Platypnea and Orthodeoxia Syndrome (POS) is a rare clinical condition characterized by positional dyspnoea and arterial desaturation. Various mechanisms are related to this syndrome. The simultaneous presence of abnormal anatomical findings [aortic root dilatation, atrial septal aneurysm (ASA), Lipomatous septum, and patent foramen ovale (PFO)] and an occurring ventilation/perfusion mismatch can modify intracardiac haemodynamics leading to POS in elderly patients.

Case summary

A 70-year-old man was admitted to our emergency department suffering from neurological symptoms. A brain computed tomography scan showed a subdural haematoma and the patient underwent surgical evacuation. Some days later, he experienced an acute pulmonary insufficiency (SpO₂ 63%)
