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.
