Posture-dependent dyspnea and cyanosis after pneumonectomy.
Two months after pneumonectomy a 61-year-old man developed progressive signs of a right-to-left shunt, especially in the sitting and left lateral recumbent postures, caused by a previously asymptomatic open foramen ovale. The influence of body position on hemodynamics and ventilation was studied before and after the successful closure of the foramen ovale.
