| 目的 探讨主肺动脉窗初诊超声心动图误诊原因及确诊方法。 方法 对38例主肺动脉窗患者的初诊超声心动图资料进行回顾性分析。 结果 38例中,初诊超声心动图正确诊断21例,误诊17例,误诊率44.74％(17/38)。17例误诊病例中,6例经心导管检查确诊,5例经心脏CT确诊(其中3例结合再次超声心动图综合诊断),1例经心导管及心脏CT联合确诊,3例经手术确诊,1例经心脏MRI确诊,1例经TEE检查确诊。 结论 主肺动脉窗临床易于误诊,出现超声心动图检查结果难以解释的重度肺动脉高压或左心增大时,应首先考虑主肺动脉窗的可能,最终确诊有赖于心导管、心脏CT、心脏MRI和(或)反复超声心动图检查。 |

| Objective To discuss the causes of misdiagnosis of aortopulmonary window (AW) with initial echocardiography and the definite diagnosis method of AW. Methods Retrospective analysis of 38 patients with confirmed AW who underwent initial echocardiography during Dec 1993 to Nov 2011 was performed. Results The diagnosis of AW was made correctly in 21 patients and incorrectly in 17 patients with initial echocardiography during evaluation. Among the 17 misdiagnosed cases, there were 6 AW confirmed with cardiac catheterization, 5 confirmed with cardiac CT (3 with combined cardiac CT and repeat echocardiography), 1 confirmed with cardiac catheterization and CT, 3 confirmed with surgery, 1 confirmed with cardiac MRI and 1 confirmed with TEE. Conclusion Even meticulous echocardiography may result in a false negative diagnosis of AW. A high index of suspicion for AW is unexplainable severe pulmonary arterial hypertension or cardiac dilation. Confirmed diagnosis depends on cardiac catheterization, cardiac CT, cardiac MRI and/or repeat echocardiographic evaluation. |
