[Quantitative contrast angiography of the right ventricle: the normal indices and the problems in analyzing global and regional contractility].
Normal parameters of the right ventricular (RV) volumes, global and regional contractility were obtained in 20 normal subjects (15 men and 7 women, mean age, 47 +/- 8 yrs) by quantitative contrast RV ventriculography. Analysis of different methods of the angiographic RV volumes calculation was made. It was shown, that Ferlinz's method is adequate to get real values for RV. A new method for computer assessment of RV regional contractility was proposed--shrinkage of 5 areas in percent. The most difference (15 and 17%) between "internal" and "external" observer was found in the anterior and anteroapical segments of RV, differences in another segments were not significant (5-8%).
