[Systolic shift of the right ventricle base in patients with defects of the tricuspid valve].
A study of cinocardioangiograms taken in 29 patients (11-with "pure" tricuspidal insufficiency, 11-with a combined tricuspidal defect and 7-without any disturbances of the intracardiac hemodynamics, all of whom being examined for affections of the lungs and mediastinum) brought evidence that during the systole there occurred an intensive shifting of the right ventricle base (0.5-3 cm, the normal figure being 0.3-0.5 cm). This shift is caused by an increased stroke volume of the right ventricle due to regurgitation and high pulmonary arterial hypertension.
