[Demonstration of left-ventricular contraction anomalies with the two-dimensional sector-scanner (author's transl)].

Echocardiographic findings were compared with those obtained by cardiac catheterisation in 134 patients. Echocardiography was performed in the standard plane of the long and short axes, as well as from the cardiac apex. After dividing the left ventricle into several segments wall movement was measured in them and compared with those obtained by ventricular angiography in the right and left anterior oblique positions. It was found that in patients with left-ventricular aneurysm, proven by left ventricular angio, there was complete conformity with regard to localisation and extent of the aneurysm between the two methods of investigation. In this group 79% of the demonstrated segments could be adequately assessed and, in 91%, agreed with the radiological findings. In the group of patients without aneurysm only 68% of the segments could be adequately assessed, and 77% correctly assessed wall movement when compared with the laevocardiogram. Tracing recorded from the cardiac apex gave especially good results in demonstrating the ventricle and its segments.

[Computer-cardio-tomography in idiopathic hypertrophic subvalvular aortic stenosis--a new contribution to non-invasive diagnosis (author's transl)].

The use of computer tomography as a non-invasive procedure in the diagnosis of idiopathic hypertrophic subvalvular aortic stenosis is described. Seven patients were investigated in whom the diagnosis had been confirmed by echocardiography and laevocardiography with pressure measurements. Details of the method are discussed and computer tomography and echocardiography are compared. The features of greatest differential diagnostic importance relating to asymmetrical septum hypertrophy are discussed.

[Computer tomographic diagnosis of pericardial effusions (author's transl)].

Thirty patients with suspected pericardial effusions, or with cardiac enlargement of unknown cause were examined by computer tomography. In 19 cases a diagnosis of pericardial effusion or haematoma was made. All these cases were confirmed by echo cardiography or transthoracic puncture. The accuracy of computer tomography diagnosis did not depend on the aetiology, but could be increased by contrast enhancement. The computer tomographic criteria are enumerated and compared with those of echo cardiography. Examples of the most important differential diagnoses are discussed.

[Fast computer tomography for investigation of the heart--"computer cardiotomography". Methods and early results (author's transl)].

The early results in the investigation of normal and pathological hearts using fast computer tomography are presented. By means of tomographic sections of cadaver hearts, it has been shown that it is possible to distinguish the ventricular cavities and individual cardiac walls by this non-invasive method. Changes in volume of the ventricles and atria due to various forms of stress are easily distinguishable. Myocardial scars can be distinguished from other circumscribed myocardial defects. The particular advantages of this method, which is non-invasive, painless and easily repeatable, do not need to be stressed. The technique adds a significant dimension to previously available non-invasive diagnostic methods, such as ultrasound echo-cardiography.

[Determination of the severity of mitral stenosis by hemodynamic and echocardiographic parameters].

M-Mode and two-dimensional echocardiographic examinations were performed in 70 patients with pure or prevailing mitral stenosis. Mitral valve excursion, mitral valve opening area (MVOAe) and diastolic E-F slope were determined and compared with the gradient across the valve and the opening area obtained during cardiac catheterization. Mitral valve excursion and E-F slope showed mean values of 1.71 cm and 1.98 cm/sec. respectively and were indicative of a stenosed mitral valve. Correlation between E-F slope and gradient with MVOAe was poor. The correlation coefficient was r = +0.56 and r = 0.34 resp. MVOAe compared favorably to the mitral valve area determined at cardiac catheterization (r = + 0.96) and the gradient across the mitral valve (r = 0.90)9 We conclude: 1. Determination of the mitral valve opening area by means of two-dimensional echocardiography represents a valuable addition in the assessment of the severity of mitral stenosis. 2. M Mode echocardiography indicates the presence, but not the severity of mitral stenosis. 3. Computerized planimetry is superior to the manually planimetered opening area and represents a reproducible, exact and time-saving procedure.
