Abstract： 目的 评价房间隔缺损(ASD)患者经导管ASD封堵术后及随访中心脏形态和大小的变化.方法 应用超声心动图分别测量36例ASD患者经导管ASD封堵治疗术前、术后3 d、术后3月和术后6月右室舒张末期前后径(RVEDD)、右房长径(RAD1)右房横径(RADt)、左室舒张末期前后径(LVEDD)、左室舒张末期容积(LVEDV)和左房前后径(LAD).结果 ASD封堵术后3 d及术后3月,RVEDD、RAD1、RADt逐渐缩小;LVEDD、LVEDV和LAD逐渐增大.术后6月随访时,RVEDD继续缩小,LVEDD和LVEDV继续增大,RAD1、RADt和LAD无进一步变化.结论 ASD封堵术治疗既减轻了右心容量负荷,使右房、右室内径缩小,也改善了左心的几何构型,使已经缩小的左房、左室逐渐增大恢复.
