[Optimization of the method of x-ray contrast left ventriculography]

The authors propose their modification of the method of left ventriculography (VG) (substitution of direct VG for iv VG with an injection of a contrast medium into the right atrial chamber in combination with continuous monitoring of pressure in the LV chamber). Altogether 23 patients with a doubtful diagnosis of CHD were investigated by coronography, direct VG and iv biventriculography. All images of the left ventricle were subjected to computerized multiframe analysis. A conclusion is that the modified method is more preferable than direct VG.
