Abstract Background To evaluate the value of CT pulmonary angiography (CTPA) in evaluating the therapeutic efficacy of pulmonary embolism (PE) through the study of CT pulmonary artery obstruction index (PAOI),right ventricular function parameters and some clinical indexes related to coagulation function and cardiac function injury.Materials and methods Select 30 patients with pulmonary embolism who underwent CTPA examination before and after treatment in our hospital, sort out their CTPA images before and after treatment, and obtain PAOI and right heart function parameters, including ascending aorta diameter (AAd), main pulmonary artery diameter (MPAd), ratio of main pulmonary artery diameter to ascending aorta diameter (MPAd/AAd), right pulmonary artery trunk diameter (RPAd), left pulmonary artery trunk diameter (LPAd), the ratio of the maximum short axis diameter of the right ventricle to the maximum short axis diameter of the left ventricle (RVd/LVd), and calculate the pulmonary artery obstruction index (PAOI).At the same time obtain the required clinical indicators, including serum D-dimer, N-terminal B-type natriuretic peptide precursor (NT-proBNP), cardiac troponin I (cTnI), myocardial enzyme profile (aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK)).Results MPAd, RPAd, LPAd, RVd / LVd, PAOI, D-dimer, cTnI, CK, LDH, AST had significant changes after treatment (P < 0.05), while the other parameters and indexes had no significant differences before and after treatment (P > 0.05). PAOI is positively correlated with RVd/LVd, MPAd, D-dimer. The correlation coefficient ranges from 0.281 to 0.423, among which, the correlation with D-dimer is the closest, with a correlation coefficient of 0.423. There was no significant correlation between other parameters and PAOI (P < 0.05).Conclusion CTPA is of great significance in evaluating the severity of pulmonary embolism, right heart function and therapeutic efficacy.

Objective: This study was aimed to elucidate the feasibility of using right ventricular (RV) strain and strain rate to evaluate right heart function of Ebstein anomaly (EA) patients before and after operation. Methods: Sixty EA patients and 30 healthy controls underwent echocardiography (UCG) for evaluation of right heart function. Preoperative UCG and 1-week and 3-month postoperative UCG were performed in EA patients. RV strain and strain rate were measured on the four-chamber section of tissue Doppler imaging (TDI). Results: The strain and strain rate representative of right ventricle systolic function were reduced prior to operation. RV strain and strain rate improved after the operation (P < .001), most significantly in the basal segment and middle segment of the free wall of the right ventricle as well as the basal segment of the interventricular septum (P < .001). Conclusions: The measurement of RV strain and strain rate on tissue Doppler imaging can be employed to assess the preoperative and postoperative RV function, proves the positive effect of tricuspid valve repair on right heart function, and offers more insight on right heart function evaluation.
