Objective: To assess the ventricular systolic function and left ventricular synchrony in patients with dila-ted cardiomyopathy using single beat real-time three-dimensional echocardiography (sRT-3DE). Methods: Seventeen patients with dilated cardiomyopathy (DCM group) and seventeen healthy subjects (control group, age and sex matched) undergone sRT-3DE examination were enrolled in this study.Full-volume imaging was performed and the data were analyzed by left ventricular analysis software and right ventricular analysis software. Results: ① The parameters of left ventricular volume: In DCM group, the end systolic volume and diastolic volume were larger and the ejection fraction was lower than that of the control group (P<0.01). ②The parameters of left ventricular geometry: In DCM group, the end systolic sphericity index and end diastolic sphericity index were larger than that of the control group (P<0.01). ③ The systolic synchrony parameters were significantly larger in DCM group (P<0.01). ④ The parameters of right ventricular volume: In DCM group, the systolic volume and diastolic volume were larger and the ejection fraction was lower than that of the control group (P<0.01). Conclusions: sRT-3DE can accurately and rapidly assess the ventricular systolic function and left ventricular synchrony in patients with dilated cardiomyopathy. Thus, it's a useful and feasible routine quantification technique in patients with DCM in clinical practice.
