Objective: To evaluate the left ventricular rotation and twist in patients with constrictive pericarditis (CP) after pericardiectomy by using speckle tracking echocardiography (STE), and observe its trend over time. Methods: A total of 29 patients with CP from Department of Medical Ultrasound, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from September 2014 to December 2017 underwent echocardiography 1 week before and 1 month, 6 months, 12 months after pericardiectomy. STE was performed to obtain peak values of basal and apical rotation and left ventricular twist. Twenty-nine healthy subjects were recruited as controls in the same period. Results: The left ventricu1ar apical rotation[before surgery(6.62±3.19)°, 1 month after surgery(7.07±4.02)°, 6 months after surgery(7.88±4.46)°, 12 months after surgery(7.85±4.51)°], the left ventricu1ar twist [before surgery(10.50±4.94)°, 1 month after surgery(9.42±5.40)°, 6 months after surgery(9.59±4.62)°, 12 months after surgery(9.70±4.45)°] were significantly lower in patients with CP than those in controls [(11.22±5.17)°, (16.35±5.21)°](all P<0.05); while basal rotation in patients with CP after surgery among different time points were all significantly lower than those in controls[1 month after surgery(-3.85±3.20)°, 6 months after surgery(-3.49±2.09)°, 12 months after surgery(-3.53±2.01)°; controls(-5.57±2.78)°] (all P<0.05), with no significant difference between patients with CP before surgery (-5.22±3.14)° and controls (-5.57±2.78)°(P>0.05). There were no significant differences in left ventricular twist, basal and apical rotation in CP groups before and after surgery among different time points (all P>0.05). Conclusions: Although the left ventricular global function of patients with CP in the long postoperative period seems "normal", the left ventricular twist, basal and apical rotation are still significantly lower than those in controls. STE can be used to assess the changes of left ventricular twist and rotation in patients with CP long-term after pericardiectomy. © 2021 Chinese Medical Association
