Abstract:
Objective To evaluate the changes of left atrial (LA)functions in patients with constrictive pericarditis (CP)after pericardiectomy by two-dimensional speckle tracking echocardiography (STE).Methods A total of 41 patients with CP underwent echocardiography before and after pericardiectomy.The procedure was performed to obtain global LA longitudinal strain,the septal and lateral walls'longitudinal strain,including peak negative strain (NS),peak positive strain (PS),and total strain (TS),using speckle tracking echocardiography.Thirty-five healthy volunteers were recruited as controls. Results After pericardiectomy,global LA peak negative strain and total strain of CP increased significantly (P <0.005).There were no obvious changes in global LA peak positive strain (P >0.05).And three components of LA longitudinal strain were still lower than normal (P <0.005).LA lateral wall's total strain,peak positive strain and peak negative strain improved apparently after pericardiectomy (P <0.005),only peak negative strain increased in LA septum (P < 0.01 ).Conclusions In the early postoperative period,LA reservoir and contractile function presented significant improvements,even notable in the lateral area when compared with septum.However,all three parts of LA function were still lower than normal.STE can regionally estimate LA functions in patients with CP after pericardiectomy.
