To determine a role of the right ventricular free wall and the interventricular septum in performance of the right ventricule, either the former or the latter was replace with a non-contractile prosthesis (Teflon cloth) in normal adult dog. In the heart with a non-contractile right ventricular free wall performance of the right ventricle was fairly maintained when a prosthesis employed was identical to the free wall of the right ventricle in size. But function of the left ventricle was compromised. When a prosthesis employed was increased in size, performance of the right ventricle was well as the left ventricle was compromised. In the heart with a non-contractile septum performance of the right ventricle was compromised, but it resumed to norma as time passed. With the data obtained from these experiments it was concluded that a new pulsatile chamber could be constructed on the epicardium by suturing a non-contractile prosthesis as free wall in patients with a underdeveloped right ventricle. Performance of a newly constructed chamber was excellent in producing pressure, but expelling capacity was not satisfactory.
