Case Reports[Isolated left ventricular--right atrial shunt after blunt chest trauma (author's transl)].
A case of left-ventricular-right-atrial septal defect secundary to blunt chest trauma is described. The etiology of this type of septal defect, e. g. congenital, following aortic and mitral valve replacement, endocarditis and trauma, is discussed. Early defect closure is recommended in the presence of significant shunt volume.

[Corrected transposition of the great arteries: surgical treatment of associated cardiac defects (author's transl)].
Corrected transposition of the great arteries is often associated with other cardiac anomalies. We report our experience with the correction of the associated cardiac defects in 13 cases: ventricular septal defect with pulmonary hypertension (5 cases), ventricular septal defect with obstruction of pulmonary outflow tract (5 cases), obstruction of pulmonary outflow tract (2 cases), ostium primum defect (1 case). The possible surgical approaches for repair of the cardiac anomalies are described and the results of the operative correction are communicated. Precise diagnosis, the knowledge of the unusual disposition of the conducting tissues and new surgical approaches are prerequisite for successful correction.

Haemodynamic changes after intracoronary air embolism (0,02 ml/kg air in the left coronary artery) were studied in 16 dogs. The air was introduced in 8 animals during cardiopulmonary bypass and in 8 animals without bypass. ⋯ One half of the animals without cardiopulmonary bypass died during acute ischemia due to refractory arrhythmias; there was no mortality in the group with cardiopulmonary bypass. The left ventricular damage due to air embolization cannot be significantly reduced with cardiopulmonary bypass; the bypass only helps to "tide over" the animal during the period of acute ischemia.

[Psychiatric and neurological complications associated with cardiac surgery (author's transl)].
The following problems are discussed as the result of an own investigation done with 150 patients after cardiac surgery: 1. the differences in incidence of cerebral complications understood as 2. a probleme of qualitatively different psychopathological and neurological syndromes. 3. Causes and relationship between the clinical stages of heart-disease and neuropsychiatric complications with special regard to the question 4. congenital heart-disease versus aquired heart-disease. 5. ⋯ Remarks on the role of microembolism associated with open cardiac surgery. 7. Hereditary factors as the cause for specific psychopathological reactions.

[Classification of psychopathological disorders after open-heart surgery (author's transl)].
A better discrimination of phenomenology and severeness of psychopathological disorders after open-heart surgery has been obtained: a) There is no equal distribution of degrees of severeness, a high correlation of severeness with duration of the disorders, a low correlation with age and no dependance of sex. b) Disorientation, clouding of consciousness and disorders of awareness arise earlier, delusions, hallucinations and paranoid ideas tentatively later after surgery. c) Three psychopathological syndromes have been identified. They appear in different frequency, intensity and can be combined.
