Abstract

SINCE the pioneering work of Gibbon1 there has been great interest in the development of a mechanical heart-lung to allow isolation of these organs.2 There have been numerous difficulties, and a completely satisfactory apparatus is still to be developed. Meanwhile, a number of investigators have concerned themselves with the problem of producing valvular lesions in experimental animals but have been handicapped by the lack of equipment suitable to allow direct exposure of the proper portion of the heart. Recently, several pump methods have been described for isolating the right3 or left heart,4 and some satisfactory valve operations have been reported.5 The methods of shunting the blood from the left heart are cumbersome and limit the operator's access to the interior of the auricle. For this reason it is believed worth while to report a left heart pump shunt that allows ready access to any portion
