AB  - Right ventricular balloon pumping (RVBP), i.e., using a balloon inserted into the 
      right ventricular cavity to expel the blood into the pulmonary artery, was 
      developed in this study. The balloon, which had an unstretched volume of 
      approximately 15 ml, was made of polyurethane. In this experiment the balloon was 
      inserted into the right ventricle via the right auricle or the apical area of the 
      right ventricle. It was found that even when the natural heart was not beating, 
      the pulmonary arterial blood flow could be maintained above 80 ml/min . kg body 
      weight and the central venous pressure could be kept normal by combining RVBP and 
      LVA. When the natural heart was beating but weak, the amount of increase of the 
      pulmonary arterial blood flow induced by the application of RVBP depended on the 
      degree of right heart failure, but RVBP could supply a sufficient flow rate to 
      compensate for the failure of the right ventricle. Regurgitation through the 
      tricuspid valve was scarcely ever found during RVBP.
