Abstract
Background: Assessment of Right Ventricle (RV) systolic function has a prognostic and therapeutic value, and this assessment is not easy by using ultrasound. The aim of this study was to assess a new way to evaluate RV systolic function, by studying Right Ventricular Outflow Tract Systolic Excursion (RVOTSE). Methods:RVOTSE was measured by using M-Mode from the parasternal short-axis view at the level of the aortic valve, and was defined as the systolic excursion of the right ventricular outflow tract anterior wall endocardium in millimeter. A total of 104 patients were studied and separated into two groups: 51 patients with reduced RV function, RV fractional area change (FAC) <35% and tricuspid annular plane systolic excursion (TAPSE) <1.6 cm] and 53 patients with normal RV function (FAC) ≥35% and TAPS ≥1.6cm. RVOTSE was measured in the two groups and compared with right ventricular outflow tract fractional shortening (RVOTFS)and tricuspid annular systolic excursion velocity S¢. Results: The sensitivity of RVOTSE as a method of diagnosing reduced RV systolic function was 98% and the specificity was 100%.The sensitivity of Tissue S¢ was 96% and the specificity was 94%. The sensitivity of RVOTFS was 80% and the specificity was 98%. There was no correlation between RVOTSE and ejection fraction, also between RVOTSE and pulmonary artery systolic pressure in patients with reduced RV systolic function. There was a strong correlation between RVOTSE and the other ways to evaluate RV systolic function. Conclusion: RVOTSE is a new, simple, sensitive and specific ultrasound way to evaluate RV systolic function.
