In four patients, echocardiography showed duplication of an aortic wall echo. An aortic dissection was present in only one. Other causes for the echocardiographic pattern were abscess in the interventricular septum, mitral stenosis, and dilatation of the noncoronary sinus of Valsalva. Division of the echo from the mitral ring into two separate posterior aortic wall echoes was seen only in the p...

Abstract Background and purpose Artificial intelligence (AI) has the potential to greatly improve efficiency reproducibility of quantification in echocardiography, but gain widespread use it must both meet expert standards excellence have a transparent methodology. We developed an online platform enable multiple collaborators annotate medical images for training validating neural networks. Meth...

Echocardiographic measurements of the left ventricular dimensions and wall thicknesses at end diastole and end systole, aortic root and left atrial dimensions, mitral valve E-F slope, left ventricular ejection fraction, percent fractional shortening of the left ventricular internal dimension, estimated left ventricular mass and percentage systolic thickening of the ventricular septum and left v...

The "goose necku deformity as seen in left ventriculogrruas in the endocardial cushion defect persists after surgical treatment in whkh the subaodc deficiency of the venMcular septum is built up with prosthetic material and the natural mitral valve is replaced by a prosthesis. Anatomic studies indicate that the diaphragmatic (inflow) aspect of the left ventricle and the venMcuhu septum are shor...

OBJECTIVE To examine how fetal and infant growth are related to left ventricular mass in adult life. DESIGN A follow up study of men born during 1920-30 whose birth weights and weights at 1 year were recorded. SETTING Hertfordshire, England. SUBJECTS 290 men born and still living in East Hertfordshire, England. MAIN OUTCOME MEASURE Left ventricular mass calculated from measurements of i...

BACKGROUND Myocardial hypertrophy is a compensatory mechanism in patients with severe aortic stenosis. The left ventricle fits the systolic pressure through a hypertrophic process with increased wall thickness. The effects of elevated ventricular afterload reduce ventricular myocardial elasticity and decrease coronary flow with increased myocardial work, oxygen consumption, and mortality. Aorti...

The Taussig-Bind group of hearts is that group in which the aorta emerges completely from the right ventricle, unrelated to the position of the ventricular septal defect (VSD), while the pulmonary trunk emerges at varying degrees from the right ventricle related to the location of the VSD. Several types of surgical procedures involve the VSD in these hearts. The conduction systems in six of the...

background echocardiography is widely used to diagnose or exclude cardiac disease. the reports on reference values based on an asian population are limited. objectives we conducted a study to determine normal values for two-dimensional, m-mode, and doppler echocardiographic measurements and evaluate the relationship between these parameters and age and gender in a large, healthy iranian populat...

Results Elderly HCM patients had a lower proportion of males (53.8% elderly vs 70.3%, p=0.002). They had significantly lower left ventricular (LV) mass (153 ± 64g elderly vs 183 ± 90g, p<0.001) and lower maximal LV wall thickness (19 ± 4mm elderly vs 21±6mm, p<0.001). The most common maximal thickness segment in the elderly patients was in the basal anterior septum (35% elderly vs 22% , p=0.01)...
