INTRODUCTION M-mode echocardiography estimates of the left ventricular mass (LVM) were greater than magnetic resonance imaging (MRI) estimates. There are substantial differences between the methods both in the means of measuring and the calculation formula. The aim of this study was to investigate whether any difference in estimates of LVM between M-mode echocardiography and MRI is due to the m...

would serve this purpose for most non-specialists. The index (which must be difficult to compile in a biochemistry text) is excellent. I am not saying that this book should grace every bookshelf in the land, but for those at any stage of their careers who want a good grounding in biochemistry, this text, written by an experienced teacher, is worth the price. Auscultation and electrocardiography...

A group of 111 patients with mitral valve disease was studied by M-mode and two-dimensional echocardiography. Five left atrial thrombi were demonstrated, two of which had probably been the source of previous embolic events. Two-dimensional echocardiography was superior to M-mode in providing spatial orientation. Using multiple cross-sections the exact localisation and the size of the thrombus f...

Both two-dimensional and M-mode echocardiography provide accurate estimates of left ventricular mass. However, their reproducibility in serial studies has not been compared, although this issue is critical to evaluation of regression of hypertrophy. To determine which technique provides more reproducible estimates of left ventricular mass, three serial studies were performed prospectively in ea...

A patient with a left atrial myxoma is reported in whom M-mode echocardiography was atypical and misleading since in most transducer positions, no tumor echoes were found in the left atrium. Real time two-dimensional echocardiography provided a definitive diagnosis, demonstrating a large left atrial mass with multiple areas of calcification. One such calcified area was located adjacent to the p...

M-mode and two-dimensional echocardiographic features of mitral ring abscess are described. A round, dense echo mass between the posterior mitral leaflet and left ventricular posterior wall was demonstrated in long- and short-axis views of the left ventricle. The diagnosis of mitral ring abscess was confirmed at surgery. The superiority of two-dimensional echocardiography over M-mode echocardio...

The spontaneous closure of ventricular septal defects is frequently associated with septal aneurysm formation. In this paper we discuss the M-mode and two-dimensional echocardiographic findings in nine children with aneurysms of the ventricular septum in association with ventricular septal defects. In all patients the diagnosis was confirmed by angiography. The ventricular septal aneurysms were...
