Platypnea-orthodeoxia: assessment with a unique cardiac catheterization procedure.
A case of platypnea-orthodeoxia (orthostatic dyspnea and arterial desaturation) secondary to a patent foramen ovale in the absence of primary disease is presented. This case illustrates the use of recumbent and upright cardiac catheterization techniques for precise evaluation of the hemodynamic abnormality in this disorder.
