摘要
目的：探讨彩色实时三维超声心动图诊断双腔右心室（DCRV）的价值。方法：回顾112例右室腔狭窄病例的二维与三维超声检查，对照手术结果，分析两种超声检查方法诊断DCRV的差异。结果：手术结果有20例DCRV；二维超声诊断灵敏度80.0%，漏诊率20.0%，特异度93.5%，误诊率6.5%，阳性似然比12.308，阴性似然比0.214，诊断指数173.5%，Youden指数73.5%，一致百分率91.07%；三维超声诊断灵敏度95.0%，漏诊率5.0%，特异度98.9%，误诊率1.1%，阳性似然比86.364，阴性似然比0.051，诊断指数193.9%，Youden指数93.9%，一致百分率98.21%。二维与三维超声心动图灵敏度比较P>0.05，差异无统计学意义；特异性比较P>0.05，差异无统计学意义。结论：三维超声心动图诊断DCRV的灵敏度、特异度、阳性似然比、阴性似然比、诊断指数、Youden指数、一致百分率较之二维超声呈现增高趋势，而漏诊率、误诊率呈现减低趋势，是二维超声诊断DCRV的有益补充。
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.
