Altered left ventricular contraction pattern during right ventricular pacing: assessment using real-time three-dimensional echocardiography.
BACKGROUND Chronic right ventricular apical (RVA) pacing has been associated with increased risk of heart failure and adverse outcome. The acute effects of RVA pacing on three-dimensional (3D) ventricular function and mechanical dyssynchrony are not well known. We performed a real-time 3D echocardiographic (RT3DE) study to assess global and regional left ventricular function during RVA pacing. ...
متن کاملLeft ventricular assessment using real time three dimensional echocardiography.
T he ability to accurately assess left ventricular function non-invasively is essential for patient management since it has been known for years that left ventricular ejection fraction serves as an important predictor of long term survival. Although two dimensional (2D) echocardiography is routinely used in clinical practice to obtain information on left ventricular dimension, wall thickness, a...
متن کاملLeft ventricular ejection fraction by real-time three-dimensional echocardiography
Despite a staggering technical progress in echocardiography, in daily clinical practice assessment of left ventricular (LV) ejection fraction (EF) is still often done in a rather inaccurate two-dimensional (2D) manner. Real-time three-dimensional echocardiography (RT3DE) provides a more representative realistic view of LV volumes, thereby being the Necker cube for the naive realism of 2D method...
متن کاملReal-time three-dimensional transthoracic echocardiography.
BACKGROUND Complex anatomy of intra-cardiac structures requires spatial orientation of image in three dimensions for better understanding and enhanced image interpretation. We evaluated the feasibility and efficacy of the emerging 'real-time three-dimensional transthoracic echocardiography' technique for comprehensive assessment of cardiac anatomy, physiology, pathomorphology and pathophysiolog...
متن کاملReproducibility and accuracy of echocardiographic measurements of left ventricular parameters using real-time three-dimensional echocardiography.
OBJECTIVES We sought to determine whether assessment of left ventricular (LV) function with real-time (RT) three-dimensional echocardiography (3DE) could reduce the variation of sequential LV measurements and provide greater accuracy than two-dimensional echocardiography (2DE). BACKGROUND Real-time 3DE has become feasible as a standard clinical tool, but its accuracy for LV assessment has not...
