[Complete visualization of a coronary fistula with drainage into the superior vena cava. Diagnostic benefit of biplane transesophageal echocardiography].

A 36-year-old woman was referred because of a continuous cardiac murmur. Standard transthoracic two-dimensional echocardiography was normal. Using the transverse plane of biplane transesophageal echocardiography (TEE) a distinct dilatation of the proximal portion of the right coronary artery could be visualized.

[Qualification and quality control in sonography].

On the basis of guidelines issued by the Kassenärztliche Vereingung Hessen, some criteria for the application of sonographic examinations are presented. Minimal requirements for sonographic equipment in certain specialties are mentioned, and it is pointed out how not only case history and clinical examination but also one's own sonographic evidence are important for a accurate sonographic diagnosis.

[Acquired infundibular pulmonary stenosis. Possible late complication following radiotherapy of Hodgkin disease].

A case of infundibular pulmonary stenosis occurring years after a mediastinal radiation for Hodgkin's disease is reported. As far as the literature is known to us, a similar case has not yet been described. It is most likely that the development of the stenosis is due to the radiation therapy, since a murmur was not heard before radiation and a mild stenosis was proved several years after radiation.

[Computerized axial tomography of a heart wall tumor (author's transl)].

The use of CT has rarely reported in the work-up of cardiac patients. A case of a tumor in the wall of the left ventricle is reported which was much better visualized in regard to size, shape, and density by CT than by cardiac scanning and angiography.
