Abstract:
OBJECTIVETo determine the normal value of right ventricle using one beat full-volume real-time three-dimensional echocardiography (RT-3DE) and assess the feasibility of this technique.
METHODSOne 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 - 59 years old, 60 years old and above).
RESULTSAdequate 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). RV-EDV (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).
CONCLUSIONSRight 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.
