Left ventricular circumferential wall stress at end-diastole (preload) and at the end of isovolumic left ventricular contraction (afterload) was calculated in 48 subjects with chronic myocardial and valvular heart disease by using left ventricular internal dimensions and wall thickness measured by quantitative echocardiography, left ventricular end-diastolic pressure, and aortic end-diastolic p...

RECENT reports have focused attention on the occasional occurrence of localized constrictions in the pulmonary vascular system distal to the valve of the pulmonary artery. Such lesions have been called "coarctation of the pulmonary artery."'-3 We believe the less specific term "postvalvular stenosis" to be somewhat more inclusive and more descriptive of these defects. Schumacher and Lurie4 have...

This report of an ESC Study Group reviews current knowledge on myocardial hibernation and relevant imaging techniques, and provides an algorithm for investigation and management when a patient presents with ischaemic left ventricular dysfunction. It covers the definitions of myocardial viability, stunning and hibernation, it reviews the morphological findings in hibernation and it describes rel...

The clinical diagnosis of aneurysmal formation of the membranous ventricular septum associated with a small ventricular defect has been made previously only by means of angiocardiography. Active movement of the aneurysm during cineangiocardiography suggested the possibility of a corresponding auscultatory event. When careful auscultatory and phonocardiographic examinations were performed on 21 ...

Left ventricular circumferential wall stress at end-diastole (preload) and at the end of isovolumic left ventricular contraction (afterload) was calculated in 48 subjects with chronic myocardial and valvular heart disease by using left ventricular internal dimensions and wall thickness measured by quantitative echocardiography, left ventricular end-diastolic pressure, and aortic end-diastolic p...

Compared to pre-operative imaging modalities, it is more convenient to estimate the current cardiac physiological status from C-arm angiocardiography since C-arm is a widely used intra-operative imaging modality to guide many cardiac interventions. The 3D shape and motion of the left ventricle (LV) estimated from rotational angiocardiography provide important cardiac function measurements, e.g....

ATTENTION was first called to the "twochambered right ventricle" in recent publications.1 2 This congenital cardiac malformation is characterized by aberrant hypertrophied muscular bands that divide the right ventricular cavity into a high-pressure chamber located immediately distal to the annulus of the tricuspid valve and a low-pressure chamber distal to the hypertrophied muscle bands. The ba...

The clinical course, noninvasive and invasive diagnostic findings in 4 patients (pt) with endomyocardial fibrosis are reported. All patients (16-50 years) were in functional class III-IV (NYHA). Central venous pressure with large a- and v-waves was elevated in all; liver enlargement and peripheral edema were also noticed in all pts, and ascites in 3. An apical 2/6 systolic murmur was present in...
