Left-ventricle myocardium segmentation using a coupled level-set with a priori knowledge [PDF]
Computerized Medical Imaging and Graphics, 2006 This paper presents a coupled level-set segmentation of the myocardium of the left ventricle of the heart using a priori information. From a fast marching initialisation, two fronts representing the endocardium and epicardium boundaries of the left ...

The Thoracic and Cardiovascular Surgeon, 1986
We report a case of left ventricular myxoma in a 19-year-old man which presented as intermittent aortic valve obstruction. Echocardiography provided a comprehensive diagnosis, and excision through a left ventriculotomy was safely accomplished.

Pseudoaneurysm of the Left Ventricle
Australian and New Zealand Journal of Medicine, 1981Abstract: A case study is reported of a patient with rheumatoid arthritis who developed a pseudoaneurysm of the left ventricle after inferior myocardial infarction. The clinical diagnosis was confirmed by radionuclide cardiac blood pool imaging and by contrast ventricu‐lography; the aneurysm was successfully excised.

Asian Cardiovascular and Thoracic Annals, 2002
A 36-year-old female was admitted with dyspnea on exertion of one year's duration. Echocardiography revealed a tumor arising from interventricular septum with dynamic left ventricular outflow tract obstruction. On cardiopulmonary bypass with cardioplegic arrest, the tumor was approached through a transverse aortotomy, and excised from the ...

Pseudoaneurysm of the Left Ventricle
The Thoracic and Cardiovascular Surgeon, 1987Pseudoaneurysm of the left ventricle is relatively rare. Five patients aged 50-61 years with this disorder are the subject of this report. In 4, the pseudoaneurysm occurred following myocardial infarction and in one after aortic valve replacement. The symptoms appeared 3 months to 12 years after the primary event.

Diverticulosis of the left ventricle
American Journal of Roentgenology, 1979Nine patients, 4--60 years old, had single or multiple left ventricular outpouchings, best seen during diastole, and believed to represent congenital diverticula. The 14 diverticula, 5--28 mm long, were either along the diaphragmatic or anterior ventricular wall.

Performance of the left ventricle
The American Journal of Medicine, 1972Abstract Effective performance of the left ventricle requires the maintenance of a cardiac output as demanded by the systemic circulation without a high hemodynamic cost or pressure in the pulmonary capillary bed and without a high metabolic cost or oxygen demand by the left ventricular myocardium.

Aorta-to-Left Ventricle Tunnel Associated with Noncompaction Left Ventricle
Journal of the American Society of Echocardiography, 2006We present a case of aorta-to-left ventricle (LV) tunnel and noncompaction LV in a 26-year-old woman. She was referred to our echocardiography laboratory for evaluation of aortic regurgitation by echocardiographic examination, which led to the diagnosis of the congenital abnormality of aorta-to-LV tunnel and noncompaction LV.

Apart from left ventricular filling pressure the angiographically determined left ventricular ejection fraction (LVEF) is the most widely accepted index of left ventricular function. Since LVEF is used in many instances as a parameter to estimate the risk in patients undergoing heart surgery the clinical implications of LVEF determinations are far ...

The motion of the left ventricle. I
The Bulletin of Mathematical Biophysics, 1966The complex arrangement of the muscle fibers in the ventricular wall and the nonsymmetric contraction and expansion of the ventricle preclude the writing of a differential equation of motion for the ventricle as a whole. We can, however, describe the motion of the ventricle by describing the motion of the dimensional parameters length and diameter; the
