摘要
探讨先天性心脏病Ⅱ孔房间隔缺损 (ASD)患者是否合并肺动瓣狭窄 (PS)的过肺动脉瓣最大血流速度 (Vpvmax)界限。超声心动图 (TTE)诊断单纯性Ⅱ孔ASD 98例 ,ASD合并PS 2 7例 ,均行心外科手术治疗 ,比较TTE诊断与外科手术结果。结果显示 ,98例单纯性Ⅱ孔ASD手术证实正确 ;TTE诊断Ⅱ孔ASD合并PS 2 7例中 1 9例正确 ,另外 8例患者为单纯性ASD。研究表明 ,TTE诊断ASD患者是否合并PS时 ,应结合二维超声和Vpvmax综合判断 ,以提高诊断的准确性 ,当Vpvmax增高达 2 6 5～ 3 2 5m/s时 。
To study the diagnosis of pulmonary stenosis (PS) in patients with the secundum atrial septal defects(ASD) by the measurement of maximal velocity through pulmonary valve (Vpv max ). There were 98 cases with secundum ASD, and 27 cases with secundum ASD and PS diagnosed by echocardiography(TTE). All the cases with secundum ASD were confirmed by surgery. The diagnosis of 19 cases out of 27 cases as diagnosed by TTE were confirmed by surgery, and the other 8 cases were simple secundum ASD. These results suggested that the two dimensional echocardiography and Vpv max should be utilized in order to achieve a better diagnostic accuracy in the diagnosis of PS in the patients with ASD, and PS should be considered if the Vpv max increased to 2 65 to 3 25m/s.
