Platypnea-orthodeoxia syndrome is a rare and underdiagnosed condition. It is characterized by dyspnea and hypoxemia in the standing position with improvement in the dorsal decubitus position. Diagnosing is a challenge, and its ignorance can lead to unnecessary studies. Generally, it is due to anatomical and functional defects that generate a right-left shunt. We present the case of a patient with atrial septal defect, atrial septal aneurysm and aortic dilatation, an unusual combination. This is the first reported case in Colombia.
