Abstract: Objective To investigate changes of left ventricularregional systolic function after surgical treatment of left ventricular aneurysm (LVA) by realtime threedimensional echocardiography (RT-3DE). Methods From February 2009 to February 2010, 14 consecutive patients who were diagnosed to have coronary artery diseases with LVA underwent surgical repair and coronary artery bypass grafting (LVA group) in our hospital. All patients of the LVA group were followed up for a mean period of 4 months. Twodimensional echocardiography (2DE) and RT-3DE were performed before operation and during the follow-up. Left ventricular regional ejection fraction (EF) was acquired by Qlab software analysis. At the same time, 12 healthy persons were included as controls (control group). Statistical analyses were carried out to compare left ventricular regional EF between the LVA group (before operation and 4 months after operation) and the control group. Results Contrary to the control group, preoperative regional EF of the LVA group increased from apex to base. In addition to the inferior basal segment, lateralinferior basal segment and anteriorinferior basal segment, regional EF in the remaining 14 segments were significantly lower than that of the control group (P＜0.05). At postoperative followup, regional EF recovered the increase from base to apex, and there was no significant difference between anteriorinferior segment and lateral segment regional EF of the LVA group and those of the control group (P＞0.05), while regional EF of other segments in the LVA group was lower than that in the control group (P＜0.05). Conclusion RT-3DE is an effective method to assess left ventricular regional systolic function in patients with LVA. After LVA repair and coronary artery bypass grafting, regional systolic function will restore to the normal direction of progressive increase, and some nonaneurysm segments systolic function will go back to normal.
