Abstract

Objective: To explore the accuracy of strain rate imaging(SRI) in quantitative assessment of left ventricular function in patients with anomalous origin of the left coronary artery from the pulmonary artery(ALCAPA)． Methods: Thirty-nine healthy subjects and 16 children with ALCAPA were studied． Regional strain rate in the mid, basal and apical segment of left ventricular wall and septum in systolic, early diastolic and late diastolic period and the systolic strain were measured, and these data were compared and analyzed． Results: The parameters of systolic strain and strain rate, diastolic strain and strain rate in the ALCAPA group before operation are significantly lower than that in the normal group(P<0.01). After coronary reimplantation, these parameters increased more significantly(P<0.01), but still lower than that in the normal group(P<0.05). Conclusions: Compared with normal children, left ventricular function is impaired in patients with ALCAPA, coronary reimplantation should be performed early to improve ventricular function. The change of left ventricular function before and after operation in patients with ALCAPA could be accurately assessed by strain rate imaging.
