Wennevold, 1966), and further alternative means of obtaining haemodynamic information from the left side of the heart seem invaluable.Levy and Lillehei (1964) described a method of obtaining pressure gradient readings across the aortic and mitral valves by the use of a needle-type short catheter introduced to the ventricle directly through the chest wall at the cardiac apex.We have modified this technique by using a simpler needle- type teflon catheter, and, in a proportion of patients, by introducing a larger catheter for ventriculography and aortography by a variation of the Seldinger technique.After evaluating it in dogs we have now employed the method in a pilot study of 55 patients.
