A real-time, phased-array, two-dimensional echocardiography system was used to assess mitral valve motion in 30 catheterized patients with pure mitral stenosis. Suitable images for analysis of mitral valve motion were obtained in 25 patients. The valve leaflets were most thickened and immobile at the leaflet tips while maximum mobility was at the leaflet body. Diastolic movement of anterior mit...

conclusions the patient underwent surgery several days later with complete resection of the tumor and coronary stent retrieval but his left ventricular ejection fraction remained poor after several months and he was referred for cardiac transplantation. introduction cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. case presentation we describ...

arious techniques have been utilized for the asVsessment of mitral valve prosthesis function in man. Of the external methods, phonocardiography, fluoroscopy, and echocardiography have been most frequently employed. Routine cardiac catheterization, including pressure measurement and left ventriculography, supplies important data but does not directly estimate blood flow through the d c i a l val...

The continuity equation suggests that a ratio of velocities at two different cardiac valves is inversely proportional to the ratio of cross-sectional areas of the valves. To determine whether a ratio of mitral/aortic valve orifice velocities is useful in determining aortic valve area in patients with aortic stenosis, 10 control subjects and 22 patients with predominant aortic stenosis were exam...

A three year old girl with severe congenital mitral stenosis was successfully treated by percutaneous balloon dilatation of the mitral valve. Cardiac catheterisation and cross sectional and Doppler echocardiography indicated that the orifice of the mitral valve had doubled in area. A small atrial septal defect was found at follow up cardiac catheterisation and angiography. Balloon dilatation of...

Infants with severe aortic valve stenosis often are critically ill and require urgent surgical treatment. Currently, angiography is used at the time of cardiac catheterization to diagnose aortic valve stenosis. However, the use of this test may be hazardous in an unstable infant and may precipitate hemodynamic and clinical deterioration before surgery. Therefore, a noninvasive method of accurat...

Primary cardiac tumours are quite rare and most of these tumours are benign. In this report, a patient presented with heart failure symptoms attributable to severe mitral valve stenosis. Echocardiography showed a dense left atrial mass causing functional mitral valve obstruction. The morphological and intraoperative presentation was highly suggestive of a myxoma but histopathological examinatio...

Eleven patients with dextro-transposition of the great vessels (TGV) and subpulmonic (left ventriclar outflow) obstruction documented by cardiac catheterization and angiography were studied by echocardiography. Echocardiographic features were which characterized the outflow obstruction included a) prolonged diastolic apposition of the mitral valve with the ventricular septum (10 patients), b) s...
