Abstract

The effects of right ventricular cardiotomy were investigated in a total of 28 dogs. Half of the group were studied by high-speed cinematography and half by means of ventricular function curves. In both groups long vertical ventriculotomies were done in eight animals and transverse ventriculotomies were performed in six. Adverse effects on the contraction and function of the right ventricle were observed in the animals undergoing vertical cardiotomy. On the other hand, transverse ventriculotomy did not result in significant abnormalities of right ventricular performance. It is concluded that transverse ventriculotomy is more physiologic and may be the incision of choice, especially in the higherrisk group of patients with pulmonary hypertension.
