Abstract:
Objective To determine the normal value of right ventricle using one beat full-volume real-time three-dimensional echocardiography ( RT-3 DE) and assess the feasibility of this technique.Methods One beat full volume images were acquired at the apical 4 chamber view in 129 healthy volunteers.The right and left ventricular volumes were examined with the eSie LVA and RVA.The subjects were divided into 2 gender groups (male and female) and 3 age groups (20 -39 years old,40 -59years old,60 years old and above).Results Adequate data were obtained in 129 subjects.The RV-EDV was (92.4±21.3)ml,RV-ESV (34.6 ±9.2) ml,RV-SV (57.8 ±13.9) ml,RV-EF (62.5 ±5.0) ml.EDV,ESV,and EF were significant different while SV was similar between RV and LV ( all P ＜ 0.05 ).RVEDV(r=0.517,P=0.001),RV-ESV(r=0.588,P=0.001) and RV-SV(r=0.409,P=0.001)were correlated well with BSA.RV-EDV,RV-ESV and RV-SV were significantly higher in males than in females (all P ＜ 0.001 ).RV-EDV.RV-SV and RV-EF decreased with aging ( P ＜ 0.05 ).Conclusions Right ventricle function can be measured noninvasively by RT-3DE with high feasibility. This novel method contributes to the detailed study of right heart function in various cardiovascular diseases.
