ABSTRACT
Objective To explore the feasibility of right ventricular outflow tract index in the evaluation on right ventricular systolic function and its relationship to other right ventricular functional indices generally accepted in clinical practice. Methods Sixty-one patients with heart failure were randomly selected and divided into elevated right side pressure group and normal right side pressure group by pressure gradient ≥35 mm Hg aquired from tricuspid regurgitation velocity. Twenty-four healthy adults were selected as control group. All the people experienced transthoracic echocardiography. Right ventricular longitudinal excursion(RVLX), right ventricular ejection fraction(RVEF), right ventricular outflow-tract fractional shortening(RVOTFS) and right ventricular ejection time(RVET) were measured, and their differences were compared between healthy adults and heart failure patients as well as between elevated right side pressure group and normal right side pressure group. Relationships of RVOTFS with other right ventricular functional indices were also analyzed. Results Compared with healthy adults, heart failure patients had lower RVOTFS((0.49)?(0.13) vs (0.22)?(0.09),P
