[Effect of contrast ventriculography of the left ventricle on coronary hemodynamics in patients with ischemic heart disease].
The effect of left ventricular (LV) contrast ventriculography (VG) on the state of intracardiac hemodynamics during the administration of a contrast medium and 30-40 sec. after it was investigated in 48 CHD patients. It followed retrograde catheterization of the left ventricle by a parallel use of two catheters that permitted recording intraventricular pressure directly during LV VG. The performance of left VG with 76% urografin administered in a dose of 0.6-0.8 ml/kg with the rate of 13-15 ml/s produced no significant change in the state of intracardiac hemodynamics, relaxation and pumping function of the LV in the course of the first three contrasted cardiocycles. Transitory disorder of hemodynamics observed in the patients after contrast VG was restored by itself in 15-20 min.
