摘要
目的比较标准化右心声学造影与传统的右心声学造影检测卵圆孔未闭右向左分流的敏感性及特异性。方法选取临床怀疑有右向左分流者500例,随机采用标准化右心声学造影方法和传统的右心声学造影方法进行右心声学造影检查,以经食管超声或术中造影证实的卵圆孔未闭为金标准,比较两种右心声学造影方法对卵圆孔未闭患者诊断的敏感性和特异性。结果 500例患者经食管超声及术中证实共有卵圆孔未闭患者278例。标准化右心声学造影检测卵圆孔未闭的灵敏度(92. 8%)和准确度(95. 2%)显著高于传统的右心声学造影(分别84. 2%和89. 8%,均P <0. 01),两种方法对卵圆孔未闭患者诊断的特异度无显著差别(98. 2%vs. 96. 8%)。结论标准化右心声学造影的灵敏度和准确度高于传统右心声学造影。
AIM To compare sensitivity and specificity of standardized and traditional methods of contrast echoeardiography of the right portion of the heart in patients with patent foramen ovale. METHODS The study population consisted of 500 patients with high clinical suspicion of patent foramen ovale. Standardized or traditional methods of contrast eehocardiography of the right portion of the heart were performed randomly. Contrast transesophageal echoeardiography （TEE） or intraoperative angiography was regarded as the gold standard. Comparision was performed of sensitivity and specificity of the two methods. RESULTS Among 500 patients, a total of 278 patients with patent foramen ovale were confirmed by transesophageal and intraoperative ultrasound. This correlated to a sensitivity of 92. 8% and precision of 95.2%. Standard contrast eehocardiography of the right portion of the heart was significantly higher than that of traditional methods （84. 2% vs. 89. 8% , P 〈0.01）. However, there was no significant difference in specificity of the two methods for the diagnosis of oval foramen patients （98.2% vs. 96. 8% ）. CONCLUSION The sensitivity and precision of standardized contrast echocardiography in the right portion of the heart appears to be higher than that of traditional methods.
