目的通过经胸超声心动图(TTE)评价室间隔缺损(VSD)封堵术后左心室收缩功能近、中期变化。方法对该院30例成功施行VSD封堵术治疗患者进行研究。所有患者术前3d内、术后3d、术后3月和术后6月分别进行TTE检查,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VSD封堵术后LVEDD、LVEDV、LVESV和LVSV逐渐减少;LVEF和LVFS封堵术后3d、术后3个月和术后6个月较术前下降,而术后3个月、术后6个月与术后3d比较无明显差异。结论VSD封堵术后,伴随左室扩张得到纠正,代偿增强的左心室收缩功能逐渐恢复正常。
Objective To evaluate the changes of left and right ventricular systolic function in patients with ventricular septal defect (VSD) after transthoracic echocardiography (TTE). Methods 30 cases of successful treatment of patients with VSD closure were studied. All patients underwent TTE within 3 days before surgery, 3 days after surgery, 3 months after surgery and 6 months after surgery. 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 LVEDD, LVEDV, LVESV and LVSV gradually decreased after VSD occlusion. LVEF and LVFS occured 3 days, 3 months and 6 months postoperatively compared with that before operation, while 3 months postoperatively and postoperatively There was no significant difference between 6 months and 3d after operation. Conclusion After VSD closure, left ventricular dilatation is corrected and compensatory enhancement of left ventricular systolic function gradually returns to normal.
