Changes in right ventricular systolic function after transcatheter aortic valve implantation assessed by two-dimensional speckle tracking echocardiography.
Evolución de la función sistólica ventricular derecha tras implante de válvula aórtica percutánea con ecocardiografı´a speckle tracking bidimensional To the Editor, In recent years, left ventricular function has been shown to improve in patients with severe aortic stenosis treated with transcatheter aortic valve implantation (TAVI), 1 and a reduction of left ventricular hypertrophy has also bee...
متن کاملAssessment of early diastolic left ventricular function by two-dimensional echocardiographic speckle tracking.
AIMS To determine whether the degree of untwisting of the apex in early diastole is related to established parameters of diastolic function. METHODS AND RESULTS Data from 71 hospital inpatients with preserved left ventricular systolic function who underwent standard two-dimensional echocardiography was analysed using an off-line speckle tracking software package. Early diastolic mitral inflow...
متن کاملRight ventricular function in coronary slow flow: A two-dimensional speckle-tracking echocardiographic study.
OBJECTIVE Coronary slow-flow phenomenon (CSFP) is described as protracted passage of angiographic contrast agent to the distal portion of the epicardial coronary arteries in the absence of stenosis. Few studies have addressed the effects of this condition on right ventricular (RV) dysfunction. The present objective was to assess RV function in CSFP via 2-dimensional speckle-tracking echocardiog...
متن کاملEvaluation of myocardial mechanics with three-dimensional speckle tracking echocardiography in heart transplant recipients: comparison with two-dimensional speckle tracking and relationship with clinical variables.
AIMS Two-dimensional speckle-tracking echocardiography (2D-STE) is limited by its inability to track tissue motion in three dimensions. This is particularly relevant in heart transplant recipients, in whom marked translational motion of the transplanted heart is present. We aimed to compare 3-dimensional (3D)- and 2D-STE-derived strain parameters, and to identify clinical features associated wi...
متن کاملAssessment of left ventricular twist mechanics in Tako-tsubo cardiomyopathy by two-dimensional speckle-tracking echocardiography.
AIMS To assess left ventricular (LV) twist mechanics in patients with Tako-tsubo cardiomyopathy (TTC). METHODS AND RESULTS Two-dimensional strain and LV twist by speckle-tracking echocardiography was performed in 17 consecutive patients with typical TTC according to the Mayo clinic criteria [78 ± 8 years, 88% women, and mean left ventricular ejection fraction (LVEF) 45 ± 10%], at the acute ph...
