Prognostic significance of residual functional mitral regurgitation in hospitalized heart failure patients with chronic atrial fibrillation and preserved ejection fraction after medical therapies
Journal of Echocardiography - Tập 17 - Trang 197-205 - 2018
Functional mitral regurgitation (MR) can be seen in patients with atrial fibrillation (AF), even without left-ventricular (LV) systolic dysfunction, as a result of left atrial enlargement. The purpose of this study was to evaluate the prognostic significance of residual functional MR in hospitalized heart failure patients with chronic AF and preserved LV ejection fraction (pEF) after medical thera...... hiện toàn bộ
Biventricular takotsubo cardiomyopathy with asymmetrical wall motion abnormality between left and right ventricle: a report of new case and literature review
Journal of Echocardiography - Tập 17 - Trang 123-128 - 2019
Takotsubo cardiomyopathy (TC) is characterized by transient wall motion abnormalities most commonly involving the left ventricle (LV). Although biventricular TC had been considered uncommon condition, recently biventricular TC has been reported as a new variant observed in 19–42% of all TC presentations. Since biventricular TC has a poor prognosis as compared with isolated TC, it is important to d...... hiện toàn bộ
Resonant cardiac chamber with diastolic thrill
Journal of Echocardiography - Tập 13 - Trang 69-71 - 2015
A 70-year-old man with a diastolic Levine V/VI musical murmur came to our department. Doppler color-flow imaging showed eccentric severe aortic regurgitation. M-mode echocardiography demonstrated fluttering of the anterior mitral leaflet and fine tremors at the aortic root. The curved M-mode representation of the myocardial strain rate showed that the basal septum was encoded in a mixture of blue ...... hiện toàn bộ
Inverted left atrial appendage presenting as a large left atrial mass
Journal of Echocardiography - Tập 8 - Trang 30-32 - 2009
Inverted left atrial appendage (ILAA) is a rare phenomenon. We describe a patient with mitral stenosis who presented with a homogenous mass in the left atrium, mimicking a large thrombus. The patient was sent to surgery and no thrombus was found; intraoperative examination by the surgeon revealed an ILAA. We briefly discuss the main features of this entity and also some aspects of the differential...... hiện toàn bộ
Apical flow and wall motion dynamics in left ventricular outflow obstruction: a case report

Quantification of mitral valve apparatus by three-dimensional transesophageal echocardiography: in vitro validation study comparing two different analysis systems
Journal of Echocardiography - Tập 9 - Trang 130-136 - 2011
Two commercial software systems have become available for quantitation of mitral leaflet and annulus geometry based on three-dimensional (3D) transesophageal echocardiographic (3DTEE) images. The aim of this study is to investigate the accuracy and compatibility of the three-dimensional (3D) measurements by Real View® and MVQ®. 3DTEE images were obtained from phantom models with saddle-shaped annu...... hiện toàn bộ
Current status of stress echocardiography: is it a required procedure for every sonographer?
Journal of Echocardiography - Tập 12 - Trang 129-137 - 2014
Stress echocardiography is a versatile modality in the clinical cardiology. In its earlier days, its sole indication was restricted to diagnosing coronary artery disease. However, in response to the rapid development of ultrasound technology and analysis software, the indications have now evolved with expansion to several fields of cardiovascular disease. I reviewed previous stress echocardiograph...... hiện toàn bộ
Right ventricular diastolic dysfunction in patients with left ventricular hypertrophy: analysis of right ventricular myocardial relaxation using two-dimensional speckle tracking imaging
Journal of Echocardiography - Tập 7 - Trang 25-33 - 2009
Although several previous studies have suggested the presence of right ventricular (RV) diastolic dysfunction in patients with hypertrophic cardiomyopathy (HCM) and those with hypertensive left ventricular hypertrophy (HT-LVH), the mechanisms are still unclear. This study aimed to clarify the relationship between the RV global diastolic dysfunction in these patients and the regional myocardial dia...... hiện toàn bộ
