OBJECTIVES We sought to determine whether radial left ventricular (LV) asynchrony in patients with heart failure predicts systolic function improvement with cardiac resynchronization therapy (CRT). BACKGROUND We quantified LV wall motion by echocardiography to correlate the effects of CRT on LV systolic function with wall motion synchrony. METHODS(More)
OBJECTIVES We sought to validate high-resolution transthoracic real-time (RT) three-dimensional echocardiography (3DE), in combination with a novel semi-automatic contour detection algorithm, for the assessment of left ventricular (LV) volumes and function in patients. BACKGROUND Quantitative RT-3DE has been limited by impaired image quality and(More)
AIMS To assess if myocardial deformation imaging allows definition of an optimal left ventricular (LV) lead position with improved effectiveness of cardiac resynchronization therapy (CRT) on LV reverse remodelling. METHODS Circumferential strain imaging based on tracking of acoustic markers within 2D echo images (GE Ultrasound) was performed in 47 heart(More)
OBJECTIVES We studied the acute effects of cardiac resynchronization therapy (CRT) on functional mitral regurgitation in heart failure (HF) patients with left bundle branch block (LBBB). BACKGROUND Both an decrease [corrected] in left ventricular (LV) closing force and mitral valve tethering have been implicated as mechanisms for functional mitral(More)
OBJECTIVE To evaluate whether myocardial strain and strain rate calculated from two dimensional echocardiography by automatic frame-by-frame tracking of natural acoustic markers enables objective description of regional left ventricular (LV) function. METHODS In 64 patients parasternal two dimensional echocardiographic views at the apical, mid-ventricular(More)
The aim of the study was to quantify a 1-year change in left ventricular (LV) mass index (MI) and systolic LV function in 30 patients with pure severe aortic stenosis by means of serial 3-dimensional (3-D) echocardiography. To assess the completeness of LVMI regression after 1 year, we compared the postoperative mass of patients with mass values of 30(More)
BACKGROUND There is a paucity of detailed and controlled studies on the action of ethanol and alcoholic beverages on gastric emptying in humans. This study was designed to compare the effect of beer, red wine, whisky and their comparable pure ethanol solutions on gastric emptying in a controlled and randomized investigation. METHODS On separate days, 10(More)
OBJECTIVES We studied in a multicenter setting the accuracy and reproducibility of 3-dimensional echocardiography (3DE)-derived measurements of left atrial volume (LAV) using new, dedicated volumetric software, side by side with 2-dimensional echocardiography (2DE), using cardiac magnetic resonance (CMR) imaging as a reference. BACKGROUND Increased LAV is(More)
