Objective To explore the echocardiographic characteristics of right heart in tibetan patients with hepatic echinococcosis at Tibetan plateau. Methods Randomly selected 113 tibetan patients with hepatic echinococcosis which diagnosed by ultrasound scan，including 62 cases of alveolar echinococcosis（AE），51 cases of cystic echinococcosis（CE），and 49 tibetan residents living in same area as control group（C）.Routinely measured echocardiographic parameters of right heart，calculated the rate of increased pulmonary arterial pressure. Results hepatic echinococcosis usually present a solitary lesion and can easily involve the right liver. The overall distribution in right ventricular anteroposterior diameter（RV），right ventricular transverse diameter（RVTD），pulmonary artery forward flow velocity（PV） and pulmonary artery forward flow pressure（PVG） were different among three groups，and the AE group and the CE group were significantly lower than that in control group（P＜0.05），but there was no significant difference between the AE group and the CE group；The overall distribution in E/e ratio and TAPSE were different among three groups，and the E/e ratio in CE group was significantly higher than that of controls（P＜0.05）；the TAPSE in AE group and CE group were significantly lower than that in control group （P＜0.05）；There was no significant difference in the rate of increased pulmonary arterial pressure among three groups, specifically, AE: 38%, CE : 35%, and C: 31% respectively. Conclusion Tibetan patients with hepatic echinococcosis present a much thinner and smaller right ventricle as well as an impaired right ventricular function than that of controls.
