摘要(Abstract)：
目的 分析房间隔缺损 (ASD)直径的经胸超声心动图 (TTE)测量值、经食管超声心动图(TEE)测量值、左房造影测量值及肺循环血量 体循环血量比值 (QP QS)与球囊导管测量的ASD直径的关系 ,评价ASD直径的各种测量方法在介入治疗中的应用价值。方法 全组共 40例 ,均于心导管检查前 1周内接受TTE及TEE检查 ,以测量到的ASD直径的最大值作为该ASD直径的TTE及TEE测量值。右心导管检查中以Fick法计算QP QS。 14例患者行左房造影测量ASD直径。 40例均于心导管术中以球囊导管测量ASD直径并以此作为ASD直径的球囊测量值。结果 ASD直径的TTE、TEE及造影测量值均明显小于球囊测量值 (P <0 0 0 1) ,但TTE、TEE的测量值与球囊测量值显著相关 ,(r=0 85 8、0 834,P <0 0 0 1) ,且TTE测量值与球囊测量值的相关性较TEE更高 ,而左房造影测量值与球囊测量值无统计学相关 (P =0 2 14)。QP QS与球囊测量值亦存在统计学相关 (r=0 373)。ASD的TTE和TEE测量值之间无统计学差异 (P =0 2 0 ) ,但有良好的相关性 (r =0 771,P <0 0 0 1)。结论 ASD直径的球囊测量值仍应作为选择封堵器的“金标准” ,应用TTE可较准确的独立估测ASD直径的球囊测量值 ,可用于介入治疗的患者。TEE对球囊测量值的估测并不优于TTE ,但可提供更多的?
