Entry into the left atrium during cardiac catheterization may be essential for full assessment of the hemodynamic situation, particularly for the accurate calculation of pulmonary blood flow and pulmonary arteriolar resistance. The retrograde transaortic transmitral technique of left atrial catheterization has been described in adults but no detailed reports are available for the pediatric age group. Experience of this technique in 43 children with congenital heart disease is now presented, with a success rate of 67 per cent and a low incidence of complications. This method compares favorably with other methods of left atrial catheterization when the interatrial septum is intact.
在心脏导管插入术中进入左心房对于全面评估血流动力学状况可能至关重要，特别是对于准确计算肺血流量和肺小动脉阻力而言。逆行经主动脉二尖瓣途径的左心房导管插入术已在成人中有所描述，但尚无针对儿童年龄组的详细报告。现将该技术在43例先天性心脏病患儿中的应用经验予以介绍，成功率为67%，并发症发生率较低。当房间隔完整时，该方法与其他左心房导管插入术方法相比具有优势。
