Intermittent functional closure of patent ductus arteriosus in a ten-month-old infant; hemodynamic documentation.
We describe a ten-month-old patient in whom intermittent patency and closure of the dectus arteriosus was observed clinically, and in whom this observation was uniquely demonstrated at the time of cardiac catheterization. The hemodynamics of this patient and the physiology of ductal closure are discussed.
