【目的】评价动脉导管未闭(PDA)应用国产蘑菇伞封堵治疗后及中期随访的左室功能变化。【方法】对45例PDA患者封堵术前、术后及3~6个月随访时行经胸超声检查(TTE),测量左室舒张末期内径(LVEDD)、左室舒张末期容积(LVEDV)、左室收缩末期容积(LVESV)、左室每搏量(LVSV)、左室射血分数(LVEF)和左室短轴缩短率(LVFS)。【结果】封堵术后LVEDD、LVEDV、LVESV与LVSV减少,3~6个月随访时进一步下降;LVEF与LVFS封堵术后较封堵术前下降,3~6个月随访时未见进一步改变。【结论】国产蘑菇伞封堵治疗PDA,减轻左室容量负荷,封堵术后早期代偿增强的左室功能回复,中期随访左室功能维持在正常水平。
【Objective】 To evaluate the changes of left ventricular function in patients with patent ductus arteriosus (PDA) treated with domestic mushroom umbrella closure and after follow-up. 【Methods】 Twenty-five PDA patients underwent transthoracic echocardiography (TTE) at the time of preoperative, postoperative and 3 to 6 months postoperative occlusion. Left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic volume (LVEDV) Left ventricular end-systolic volume (LVESV), left ventricular stroke volume (LVSV), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS). 【Results】 The results showed that the LVEDD, LVEDV, LVESV and LVSV decreased after occlusion and further decreased at 3-6 months of follow-up. LVEF and LVFS occluded more preoperatively than those before occlusion, and no further follow-up was observed at 3-6 months change. 【Conclusion】 Domestic mushroom umbrella occlusion treatment of PDA, to reduce the left ventricular volume load, early postoperative closure of compensatory enhancement of left ventricular function recovery, mid-term follow-up left ventricular function maintained at normal levels.
