[The regional contractile function of the normal right ventricle and in congenital heart defects]

The authors have developed a method for studying the regional contractile function of the right ventricle (RV) performed by cineangiocardiogram in two projections. It allowed an analysis of the regional contractile function of the RV to be performed in patients with hypervolemic exercise of RV and hyperkinetic load to RV, and to compare them with normal conditions. It was established that the regional contractile function of the input and output parts are not equivalent and that there are reliable differences in changes of contractility of the output part of the RV in patients with stenosis of the pulmonary artery as compared with normal state.
