Abstract：Objective: To assess the value of real-time three-dimensional echocardiography in diagnosing double-chambered right ventricle(DCRV). Methods: The two-dimensional and three-dimensional echocardiographic data of 112 patients with right ventricular stenosis were reviewed. The surgical results were contrasted and the two methods of ultrasounic examination in diagnosing DCRV were analyzed. Results: After operation, 20 patients have suffered from DCRV. The sensitivity, the missed diagnosis rate, specificity, misdiagnosis rate diagnosed by two-dimensional echocardiography were respectively 80.0%, 20.0%, 93.5% and 6.5%. The positive likelihood ratio was 12.308, while the negative likelihood ratio was 0.214. The diagnostic index and Youden’s index were 173.5% and 73.5%. On the other hand, the sensitivity, the missed diagnosis rate, specificity, misdiagnosis rate diagnosed by three-dimensional echocardiography were respectively 95%, 5.0%, 98.9% and 1.1%. The diagnostic index and Youden’s index were 193.9% and 93.9%. The sensitivity of two-dimensional echocardiography compared with that of three-dimensional echocardiography, P>0.05, there was no significant difference. Their specificity compared, P>0.05, there was no significant difference. Conclusions: The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic index, Youden’s index of three-dimensional echocardiography were higher than those of two-dimensional echocardiography, while the missed disgnosis rate, the misdiagnosis rate were lower, which shows three-dimensional echocardiography is a helpful supplement in diagnosing DCRV.
