Abstract Objective: To analyze the three-dimentional ultrasonic features of right heart infective endocarditis(RHIE) and provide reference for the diagnoses of infective endocarditis caused by travenous injections. Methods: Seventy three-dimentional ultrasonic images of infective endocarditis were reviewed. The prevalence of RHIE related to travenous injections(14 cases) and the value of right heart vegetations diagnosed by three-dimentional ultrasound(22 cases) were analyzed. Results: The prevalence of 14 travenous drug abusers and 56 non-travenous drug abusers compared, 9 of the former and 14 of the latter suffered from RHIE(P<0.05). There were significant differences between them; twenty-two cases which confirmed as right heart vegetations by operations were examined respectively by two-dimentional ultrasound and three-dimentional ultrasound(P<0.05). Conclusion: While the diagnoses of infective endocarditis caused by travenous injections was diagnosed, three-dimentional ultrasound is a necessary supplement to two-dimentional ultrasound.
