XPLANE technique for evaluation on right ventricular function of atrial septal defect patients before and after percutaneous intervention / 中国医学影像技术

ABSTRACT

Objective: To explore the application value of right ventricular longitudinal shortening fraction (LSF) obtained with XPLANE technique for evaluation on changes of right ventricular function in patients with atrial septal defect (ASD) before and after percutaneous intervention (PI), and to analyze relative impact factors. Methods: Totally 68 patients with ultrasound-diagnosed ASD who accepted PI were collected. All patients underwent echocardiography before PI, 1 month and 3 months after PI, respectively. Then LSF of apical plane of 2-chamber (LSFAP2) and apical plane of 4-chamber (LSFAP4) images and the mean value of LSFAP2 and LSFAP4 (LSFAPM), tricuspid annular plane systolic excursion (TAPSE), pulmonary hypertension (PH) grading, as well as right ventricle end-diastolic diameter/left ventricle end-diastolic diameter (RVEDD/LVEDD) grading before and after PI were measured and compared. The correlation of LSFAP2, LSFAP4, LSFAPM and TAPSE, and the impact factors of LSFAPM were analyzed. Results: RVEDD/LVEDD (H=76.07, 77.74) and PH (H=42.02, 49.83) grading 1 month and 3 months after PI were lower than those before PI (all P0.05). There were statistical differences of remaining LSFAP2, LSFAP4, LSFAPM and TAPSE before and after PI (all P<0.05). LSF parameters before and after PI were positively correlated with TAPSE (all P<0.05).Age and preoperative PH grading were the common impact factors of LSFAPM before and after PI. Conclusion: XPLANE technique can be used to effectively observe the changes of right ventricular function in patients with ASD before and after PI. The morphology and function of right ventricle in patients can be improved with PI, and the variation trend of LSF parameters and TAPSE before and after PI are basically similar. Age and preoperative PH grading are impact factors of right heart function before and after PI.
