Rupture of the ventricular septum after acute transmural myocardial infarction occurred in four patients aged between 53 and 79 years. The rupture was verified by means of right-side cardiac catheterization. Only in two cases did two-dimensional echocardiography reveal the rupture; in both cases the rupture site located by echocardiography was confirmed at autopsy. In each of the four patients the left-to-right shunt could be identified by means of pulsed Doppler echocardiography which showed a turbulence in the right ventricle. Furthermore, the combination of two-dimensional echocardiography and Doppler echocardiography allowed a correct localization of the turbulent left-to-right flow in all cases. In view of these findings, the combination of Doppler echocardiography and two-dimensional echocardiography may be regarded as a suitable method for a readily available, non-invasive diagnosis of ventricular septum rupture in patients with acute myocardial infarction in an intensive care unit.

The value of persistent ST-T elevations in the standard 12-lead ECG for the diagnosis of left-ventricular aneurysm (VA) was retrospectively analysed for 200 patients (171 males and 29 females) who had sustained a myocardial infarction at least 12 weeks previously. 105 patients (group 1) had a left-ventricular aneurysm confirmed by ventriculography; in 95 patients (group 2) an aneurysm had been excluded by ventriculography. Persistent ST-T elevations were present in 98 patients of group 1 (sensitivity 93.3%) and in 26 of group 2 (specificity 72.6%). In the 26 patients without VA, ST-T elevations occurred in at most three leads, but in 60 with aneurysm in four to nine leads. In addition, the area under the ST-T elevations and its height 1 mm after onset of the elevation and its maximal height were measured. The sums of the values in the limb and chest leads were statistically significantly different between the two groups for all three parameters. These measurements thus contribute to a reliable differentiation between patients with and without VA. The results also emphasize the importance of the 12 standard leads in the diagnosis of VA.

SummaryThe purpose of the study was to evaluate alterations of the hemostatic system and the effect of anticoagulant therapy in nonvalvular atrial fibrillation. A set of molecular hematologic markers was measured prospectively in 69 patients with atrial fibrillation and 28 age-matched patients in sinus rhythm. Significantly elevated levels of thrombin-antithrombin III complex (8.5 ± 1.6 vs. 2.5 ± 0.3 αg/1; p

The case of acute purulent group B streptococcal myocarditis in a 29-year-old Turk is described, no similar case having previously been published. He fell ill suddenly with gastro-intestinal symptoms, high fever and pain in arms and legs. The ECG had low voltage in the limb leads and signs of a large acute myocardial infarct. The sedimentation rate was slightly raised, an initial leukopenia was followed by leukocytosis and high enzyme activity. He died in cardiogenic shock on the third day of illness. The post-mortem examination revealed acute purulent myocarditis, and numerous group B streptococci (Strept. agalactiae) were found in the myocardium.
