摘要 目的初步探讨实时三维超声心动图左房室容积成像在评价二尖瓣成形术效果中的价值。方法应用实时三维超声心动图对30例行二尖瓣成形术患者(病例组)分别于术前、术后1周和术后6个月测量左室舒张末期容积(LVEDV)、左室收缩末期容积(LVESV)和左房最大容积(IAVmax)、左房最小容积(LAVmin),计算左室射血分数(LVEF)及左房射血分数(LAEF),并选取25例同期健康体检者作为对照组。所有容积参数均用体表面积(BSA)校正。结果(1)病例组术前与对照组比较,LVEDV/BSA、LVESV/BSA、LAVmax/BSA、LAVmin/BSA显著增高,LAEF显著降低,差异均有统计学意义(P〈0.05)。(2)病例组术后1周,LVEDV/BSA、LVESV/BSA、LAVmax/BSA、LAVmin/BSA均较术前明显降低(P〈0.05);LAEF较术前增加[(49.8±9.9)%[L(46.7±10.6)%,P〈0.05]。结论实时三维超声心动图左房室容积成像能快速准确定量评价二尖瓣成形术后的效果。
