Tetralogy of Fallot with Pulmonary Obstruction at the Level of the Conus Inlet

  • T Muller


A case of Fallot's tetralogy is described in a Black male who died of acute cardiac failure at the age of 17 years. The conus arteriosus was practically a separate chamber communicating with the right ventricle through a very small ostium. The embryology of the truncus arteriosus the bulbus cordis is discussed in the light of the anomalies described here. The question of maintenance of the pulmonary circulation in the absence of an open ductus arteriosus is discussed.
