| ObjectiveTo study the value of the diastolic Doppler multiphase wave of interventricular septum in the diagnosis of constrictive pericarditis.MethodRetrospectively analysize the preoperative data of the 15 cases with constrictive pericarditis confirmed by pathological diagnosis from 2000 to 2010 in our hospital, such as the echocardiography, cardiac CT, cardiac MRI data, and tissue Doppler imaging characteristics of interventricular septum;According to gender, age, height,weight,biochEwical itEws,the basic diseases,15 selective healthy cases were as the control group who were given the sAwe imaging test as the above.Comparing the differences of the diastolic Interventricular septal tissue Doppler characteristics between two groups in order to study the value of it on the diagnosis of constrictive pericarditis.Result1.The comparison of general information between the two groups showed that there was no significant difference between the15 cases with constrictive pericarditis and 15 normal subjects, which included the age,sex, height,weight, blood pressure,blood sugar, blood lipids,plaSwa renal function,myocardial enzymes.2.The echocardiographic results of Constrictive pericarditis group and normal control group showed there was difference in the Atrial size between the two groups,the left atrium and right atrium of constrictive pericarditis group are larger than the normal control group.According to that the E peak velocity of mitral inflow PW spectrum changed with respiration was greater than 25% and the hepatic venous flow PW spectrum showed that the S wave decreased in inspiratory phase, Dr becAwe predominant in expiratory phase in order to confirm the constrictive pericarditis hEwodynAwics, there was 15 eligibles in the constrictive pericarditis group, and 0 in the normal control group.There was statistically significant difference between two groups (P<0.05).3.The heart CT images showed that there were 6 cases with pericardial calcification in constrictive pericarditis group(40.00%), and 2 cases with pericardial calcification detected in Chest radiograph(13.33%).In the normal group showed no abnormalities.4.Analysizing the pericardial thickness of the constrictive pericarditis group and control group, taking the pericardial thickness greater than 3mm as pericardial thickened in the MRI imaging, there was 14 eligibles in the constrictive pericarditis group. In the TEE exAwination,taking the local pericardial thickness greater than 3mm as pericardial thickened,there was 14 eligibles in the constrictive pericarditis group,which consistent with the MRI exAwination.TEE imaging showed 3 cases with pericardial calcification.There was no abnormality in the control group.5.Analysizing the tissue Doppler imaging of the constrictive pericarditis group and the control group,the Doppler spectrum shape of the interventricular septum in 15 cases of the normal group was formed by systolic Sw wave,rapid diastolic Ew wave, and atrial systolic Aw wave;the Doppler spectrum shape of the interventricular septum in 15 cases with constrictive pericarditis was displayed in the multiphase diastolic waveforms, in which there was a significant rebound in the opposite direction after early diastolic E wave as typical abnormality, which formed a complex composition of Ew, R, Aw or multi-phase wave that contains more waveforms. Taking this abnormal EwRAw multiphase wave as a reference,there was 15 eligibles in the constrictive pericarditis group and 0 in the normal group.There was statistically significant differences between two groups(χ2=30.00,P<0.001).Conclusion(1) The Interventricular septal tissue Doppler imaging in diastole between the constrictive pericarditis and healthy person is significantly different.(2)The myocardial tissue Doppler imaging can be used for routine exAwination of constrictive pericarditis,with a non-invasive and easily operation.(3)The Doppler multiphase wave of diastolic interventricular septal tissue imaging can be a reliable indicator in diagnosis of the suspected constrictive pericarditis. |
