ABSTRACT
The prevalence of an echocardiographically visible patent foramen ovale (PFO) is higher in patients with obstructive sleep apnoea syndrome (OSAS) than in normal controls. We report a patient who presented with OSAS and right-to-left shunting (RLS) through the PFO in whom the RLS disappeared after treatment for 1 week with nocturnal continuous positive airway pressure (CPAP}. This case shows the role of OSA in generating on awake RLS through a PFO and its possible reversibility by CPAP. The mechanism of reversible awoke RLS through PFO in OSAS is discussed.
