1/7. Echocardiographic findings in constrictive pericarditis. A case report.The echocardiographic findings in a 73-year-old woman with constrictive calcified pericarditis are presented. The diagnosis was confirmed by physical examination, chest x-rays and cardiac catheterization. The echocardiogram demonstrated abnormal motion of the interventricular septum and of the left ventricular posterior wall, multiple thickened echoes of the posterior pericardium, and a localized dense band of anterior pericardial echoes, which corresponded to the calcification seen on the chest X-ray.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/7. Degos' disease with constrictive pericarditis: a case report.A 47-year-old man with Degos' disease was examined by echocardiography, which showed hypokinesis of the apical left ventricular wall with pericardial effusion. To evaluate the myocardial perfusion and coronary flow reserve, 201Tl scintigraphy and intracoronary Doppler flowmetry were performed. The coronary flow reserve was not decreased nor was there angiographical coronary stenosis, although a pressure study revealed constrictive dysfunction of both ventricles. The constrictive pericarditis might have been induced by pericardial vasculitis, thereby causing the left ventricular wall motion abnormality.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/7. Does atrioventricular ring motion always distinguish constriction from restriction? A Doppler myocardial imaging study.Constrictive pericarditis and restrictive cardiomyopathy can be difficult to differentiate on clinical examination. Cardiac ultrasonography is increasingly being used as the noninvasive method of choice for confirming the specific morphologic and hemodynamic abnormalities associated with either condition. Interrogation of atrioventricular valve plane motion by Doppler myocardial imaging (DMI) has been suggested as a valuable new approach that can help differentiate one from the other. We report the color DMI, pulsed DMI, and strain rate findings in 2 cases of constrictive pericarditis in which consideration of the annular motion pattern alone would not have allowed such differentiation.- - - - - - - - - - ranking = 6keywords = motion (Clic here for more details about this article) |
4/7. Reversible left ventricular dysfunction simulating a myocardial infarction after pericardiectomy.A 39 year old man with postoperative constrictive pericarditis after pericardiectomy developed major left ventricular systolic dysfunction with an anterior wall infarct pattern on ECG but no regional wall motion abnormalities by echocardiography or serum enzymatic evidence of a myocardial infarction. The left ventricular dysfunction resolved over two weeks with supportive treatment. It is postulated that this patient's transient left ventricular dysfunction and ECG changes were caused by myocardial inflammation and oedema induced by operative trauma during pericardiectomy.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/7. Septal bounce in constrictive pericarditis. diagnosis and dynamic evaluation with multidetector CT.Sixteen-slice multidetector CT findings of a case of constrictive pericarditis in a pediatric patient are presented. Multidetector CT depicted a variety of diagnostic findings including dynamic evaluation of interventricular septal motion through the cardiac cycle, documenting a diastolic septal bounce. This case illustrates the full capabilities of multidetector cardiac CT in the evaluation of pericardial pathology.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/7. Constrictive pericarditis: an unusual clinical entity suggested during dobutamine stress echocardiography.A 44-year-old female presents with disabling dyspnea and is unable to perform a regular treadmill stress test; instead a dobutamine stress echocardiogram is performed and although negative for ischemia reveals a vigorous paradoxical motion of the interventricular septum with dilatation of the inferior vena cava without respiratory variation and an increased diastolic flow signal in the hepatic veins after expiration with the infusion of dobutamine. The diagnosis of constrictive physiology is confirmed with cardiac magnetic resonance imaging (MRI) and right heart hemodynamics and the patient underwent pericardiectomy without complications with resolution of symptoms.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
7/7. Echocardiogram in pulsus paradoxus. respiration dependent cyclic changes in mitral and aortic valve motion: a case report.The mechanism of production of pulsus paradoxus was echocardiographically studied in a 74-year-old male with subacute effusive-constrictive pericarditis which developed to constrictive pericarditis under the observation. echocardiography disclosed the following phenomena during inspiration: 1) mitral valve did not open until the atrial systole, probably because of the lack of antegrade mitral flow during rapid filling phase (the E wave was not observed), 2) concomitantly, aortic valve opening decreased markedly in its grade, and 3) left ventricular ejection time (LVET) decreased and pre-ejection period (PEP) increased, resulting in a higher PEP/LVET ratio (up to 1.32). The opposite was true during expiration (PEP/LVET ratio was 0.40). This is probably the first case, in which the mechanism of pulsus paradoxus was investigated by aortic and mitral valve echograms.- - - - - - - - - - ranking = 4keywords = motion (Clic here for more details about this article) |
