Key Points

Describe a novel mechanism responsible for reopening a patent foramen ovale and triggering right-to-left interatrial shunting after pulmonary embolism despite normal right atrial pressures.
Clinical and hemodynamic evaluation of a patient presenting with acute stroke and severe hypoxemia following pulmonary embolism.
Measurement of right atrial filling pressures and assessment of interatrial shunting.
Identified right-to-left interatrial shunting across a reopened patent foramen ovale despite the presence of normal right atrial filling pressures.
Established that the persistent right-to-left shunt resulted directly in profound hypoxemia and paradoxical embolic stroke.

Implication

Case report demonstrates right-to-left interatrial shunting in a post-pulmonary embolism patient, highlighting a mechanism for stroke and hypoxemia with normal pressures.
