  • Title: [Evaluation of the overall contractile function of the right ventricle using two-dimensional echocardiography in patients with myocardial infarction].
    Author: Chikvashvili DI, Romanovskiĭ IM, Samko AN.
    Journal: Kardiologiia; 1991 May; 31(5):27-9. PubMed ID: 1895641.
    Abstract:
    The paper presents two methods for calculating the contractile function of the right ventricle (RV): (1) three-plane one with the use of short- and long-axis-cut RV; (2) single-plane one which was modified to the use of long-axis RV images in the projection of 4 chambers. A total of 56 patients with first acute gross myocardial infarction were studied. A control group included 14 healthy subjects aged 25-60 years. The proposed three-plane method for estimating the volume parameters and ejection fraction of the right ventricle was shown to correlate with contrast ventriculography significantly. A high correlation was found between the stroke output of RV (as calculated for the left ventricle by the Chapman method) and that (by the three-plane method). The RV volume values in patients with anterior or inferior myocardial infarction suggest that there is a trend to suppress RV function in the patients, but it is more specific for those with inferior myocardial infarction.
