Objective To probe into the application of left atrial volume tracking technique(LAVT)on the evaluation of right atrial function in patients with pulmonary hypertension.Methods Forty-one patients with pulmonary hypertension (pulmonary hypertension group) and 37 control subjects (control group) were involved.Right atrial maximal volume (RAVmax),right atrial presystolic volume(RAVpre),right atrial minimal volume (RAVmax),systolic right atrial filling rate (dv/dtS),early diastolic right atrial emptying rate(dv/dtE) and late diastolic right atrial emptying rate(dv/dtA) was derived by LAVT.Right atrial passive emptying volume (RAVp),right atrial passive emptying fraction (RAVpEF),right atrial active emptying volume (RAVa),right atrial active emptying fraction (RAVaEF),right atrial total emptying volume (RAVt)and right atrial total emptying fraction (RAVtEF) was calculated.All the right atrial volume parameter was corrected by body surface area to obtain right atrial volume index (RAVI).Results RAVImax,RAVImin,RAVIpre,RAVIt,RAVIa,dv/dtS and dv/dtA in pulmonary hypertension group was higher than that in control group [(78.39 ± 49.35) ml/m2 vs.(24.80 ± 11.91) ml/m2,(62.59 ± 46.56) ml/m2vs.(17.46 ± 8.40)ml/m2,(70.12 ± 48.03) ml/m2 vs.(20.02 ± 9.46) ml/m2,(18.77 ± 11.47) ml/m2 vs.(9.35 ± 6.74) ml/m2,(8.53 ± 9.81) ml/m2 vs.(3.25 ± 3.00) ml/m2,(145.85 ± 80.56) ml/s vs.(86.44 ± 48.46) ml/s,(155.63 ±126.47) ml/s vs.(67.74 ± 33.27) ml/s],and RAVIp in pulmonary hypertension group was lower than that in control group [(6.09 ± 5.16) ml/m2 vs.(10.23 ± 11.12) ml/m2],and there were significant differences (P ＜0.05).But there were no significant differences in RAVItEF,RAVIpEF,RAVIaEF and dv/dtE between two groups (P＞0.05).Conclusions In patients with pulmonary hypertension,right atrial booster pump function and reservoir function increases,while right atrial conduit function decreases.LAVT has a potential ability to evaluate right atrial function.
