Assessment Right Atrial Funtion In Patients With Hepatocirrhosis By Real-time Three-dimensional Echocardiography And Two-dimensional Speckle Tracking Imaging

Objective:To discuss the value of real-time three-dimensional echocardiography (RT-3DE) and two-dimensional speckle tracking imaging (2D-STI) in the evaluation of right atrial function in hepatocirrhosis.Methods:Study population consisted of 60 patients with hepatocirrhosis were divided into: Compensatory phase cirrhosis (group B) and decompenstion period hepatic cirrhosis (group C), and 30 control subjects(group A). RAVI were measured and calculated by RT-3DE;The strain curve were acauired in each right atrial segment with 2D-STI, the mean value of the peak strain and strain rate of systolic, early and late diastolic of right atrium (MSs, MSe, MSa, MSRs, MSRe, MSRa) were recorded.Results:Compared with group A:RAVImax, RAVImin, RAVIpre, RAVIt, ETV/e’TV in group B were increased (P<0.05), RAVIp were lower(P<0.05). Compared with group B, RAVImax, RAVImin, RAVIpre, RAVIt, ETV/e’TV in group C were further increased (P<0.05), RAVIp and MSs, MSa, MSRs, MSRa, MSe, MSRe was further lower (P<0.05). Correlation analysis show MSe and MSRe were negative correlated with ETV/e’TV (r=-0.39,-0.373, P<0.001).Conclusions:RT-3DE and 2D-STI can reflect right atrium function of patients with hepatocirrhosis, also can quantitatively evaluate the different stages of patients with hepatocirrhosis right atrium functional changes, have obvious clinical significance.
