[Left ventricular pressure response to acute volumetric overload in congenital heart disease (author's transl)]. / Respuesta de la presión ventricular izquierda a la sobrecarga volumétrica brusca de la ventriculografía en las cardiopatías congénitas.

Fifty patients with congenital heart disease were studied hemodynamically to evaluate their functionally dynamic situation. The peak systolic left ventricular pressure and the left ventricular endiastolic pressure were analyzed in basal conditions and following the volumetric overload of the left ventricular angiogram as parameters reflecting afterload and preload, respectively. Highly significant correlations were obtained among those parameters in all patients and taking in consideration different syndromic groups. Regression lines obtained from these correlations permitted to establish, in a given patient, a quantitative prediction of response to volumetric overload which can estimate qualitative situation of his ventricle into the Starling's curve.
