[The normal wall segment in coronary stenoses--a postmortal study (author's transl)].

In 384 stenotic coronary segments of extramural arteries (left main coronary artery, LAD, LCX, RCA) with degrees of obstruction greater than 50% (but less than 100%) when assessed histologically, the extent and incidence of the normal wall segment (NWS) analysed from the histological cross section were carefully evaluated. Incidence and extent of the NWS proved to be unexpectedly high: 45% of all obstructions showed a NWS of more than 25% and 74% a NWS of more than 8% of the total histological circumference of the coronary artery. Furthermore, 25% of all obstructions showed a NWS of more than 50% and 71% a NWS of more than 16% of the circumference of the residual lumen.

[Transluminal angioplasty of the coronary arteries--An analysis of the most important complications by a postmortal study in the human heart (author's transl)].

The technique of dilatation of coronary obstructions with balloon-catheters according to Grüntzig was performed in 12 hearts with 17 proximal, predominantly excentric coronary stenoses. In all stenoses we saw a significant effect of dilatation with a mean increase of the diameter from 1.2 to 1.

[Coronary morphology in patients with unstable angina pectoris. Quantitative analysis of coronary angiograms before and after one year of medical treatment (author's transl)].

The purpose of this study was to quantify coronary morphology under medical therapy in patients with initially unstable angina pectoris (Propranolol, long-term nitrates). In 25 patients the extent of 69 coronary stenoses was exactly quantified with a vernier caliper (accuracy: 0.05 mm) in two successive coronary angiograms performed in each patient at approximately one year interval.

[Isolated cardiac tumor metastasis of an osteogenic sarcoma in the heart; a case report on diagnosis and control of treatment (author's transl)].

The case of an isolated metastatic tumor of the heart from a primary osteogenic sarcoma as well as its presentation and control under therapy by investigations of nuclear medicine are reported. Both the intravital diagnosis of an isolated metastatic tumor of the heart from an osteogenic sarcoma and the presentation of a heart tumor by bone scanning are not described to this day.

[Transient systolic anterior movement of the mitral valve (SAM) without asymmetric septal hypertrophy (case report with post-mortem examination) (author's transl)].

Typical SAM of the mitral valve was detected by echocardiography in a 71-year-old patient with acute myocardial infarction. The patient showed auscultation signs of IHSS and was digitalized and hypovolemic secondary to diarrhea. Following rehydration and digitalis being discontinued, SAM was no longer seen.
