Abstract:
Objective To assess right ventricular (RV) regional and global volume and systolic function in patients with right coronary artery disease by real time three-dimensional echocardiography(RT-3DE).Methods RT-3DE images were acquired in 20 normal controls (Group A),30 patients with right coronary artery stenosis(Group B) and 10 patients with RV myocardial infarction(Group C).Volumetric RT-3DE images were analyzed by use of TomTec software,which provided regional (inflow,body and outflow) and global end diastolic volume(EDV),end systolic volume(ESV),stroke volume(SV) and ejection fraction(EF).RT-3DE quantitative data were analyzed to test repeatability.Results Compared with group A and group B,EDV and ESV of body and global were larger in group C;ESV of inflow and outflow were larger (P ＜0.05).EDV of group C was larger than group B(P ＜0.05).Compared with group A and group B,the EF of inflow,outflow and global in group C were lower(P ＜0.05).The EF of body in group C were lower than group B(P ＜0.05).There was no significant difference in regional and global volume and EF between group A and group B(P ＞0.05).The intra-observer and inter-observer's variability was low and consistency was high.Conclusions In patients with RV myocardial infarction,RV regional and global volumes were enlarged and systolic function was impaired.Evaluating right ventricular regional and global volume and function in patients with right coronary artery disease by RT-3DE has high repeatability.
