Abstract:
Objective To investigate the change features of the 3-dimensional speckle tracking imaging (3D-STI) for quantitative evaluation of whole strain of left ventricular before and after left atrial appendage closure in the patients with non valvular atrial fibrillation and to evaluate its clinical application value.Methods Thirty patients who received left atrial appendage (LAA) closure from June, 2016 to A-pril, 2017 in Changhai Hospital were enrolled as research subjects .The patients received routine ultrasonic cardiography and 3D-STI, and left ventricular fractional shortening (LVFS), left ventricular ejection fractions (LVEF), global peak longitudinal strain (GPLS), global peak circumferential strain (GPCS), global peak radial strain (GPRS)as well as global peak area strain (GPAS) were respectively detected before surgery, 2 days, 1 and 3 months after surgery.Results In the 30 patients who received LAA closure, LVFS and LVEF were evaluated by u-sing routine ultrasonic cardiography and the data detected before surgery , 2 days, 1 and 3 months after surgery were compared between the two, and results showed that there was no statistical significance, when comparisons were made between them (P>0.05).In the 30 patients who were implemented with LAA closure, GPLS, GPCS, GPRS and GPAS values were detected using 3D-STI.The detected data 2 days after surgery were significantly higher as compared with those before surgery and 1 and 3 months after surgery(e.g.GPAS:39.90 ±10.22/27.80 ± 5.00, 26.20 ±6.05, 27.60 ±7.58), and there was statistical significance, when comparisons were made between them (P<0.05).However, there was no statistical significance in the data of GPLS, GPRS, GPCS and GPAS detected before surgery and 1 and 3 months after surgery, when comparisons were made between the two (P>0.05).Conclusion 3D-STI could be used for quantitative evaluation of the changes in left ventricular systolic function before and after LAA closure.The whole strain of the left ventricle of the patient was considerably increased 2 days after surgery, and the whole strain of the left ventricle recovered to pre-surgical level one month after surgery.
