[Coronary by-pass operations in diabetic and non-diabetic patients with angina. Results of 102 coronary arteriographies (author's transl)].

The results of coronary arteriography were compared in 102 patients (55 non-diabetics and 47 diabetics) with angina. The lesions noted an arteriography were more severe in the diabetic patients: more frequent stenosis in the common trunk and three branches, and present in greater numbers (more than 4 in more than a half of the patients), with only a moderate proximal bed in 65% of the cases. By-pass operations can only be performed, therefore, in 32% of these patients as against 54% for the non-diabetic anginal patients. The operative risk also appears to be increased (1 death and 6 complications in 10 by-pass operations). It was also demonstrated that with similar lesions of the common trunk, the diabetics have radiological signs of a greater incidence of cardiomegaly and generalized hypokinesia of the left ventricle than non-diabetics. By-pass operations are impossible in about 85% of patients because of ischemic signs or evidence of necrosis in the ECG recordings of diabetic patients with angina.

[Enlarged heart caused by massive subepicardial lipomatosis with idiopathic dilatation of the right cavities].

The case is reported of a man of 48 with known longstanding gross cardiomegaly which was completely asymptomatic. Angiocardiography and coronary arteriography showed dilatation of the right side of the heart, and especially of the auricle. In addition, the ventricle was separated from the diphragm by a transparent non-fluid area. At operation, gross dilatation of the right atrium was confirmed, but no causative lesion could be found; there was also marked lipomatosis which involved particularly the area beneath the right ventricle. It is difficult to classify this most unusual case as either a classical dilatation of the right atrium, idiopathic or secondary, or as a cardiac lipoma or lipomatosis.

[Physiopathological concept of chronic cor pulmonale].

The chronic cor pulmonale is not a disease but a syndrome. The peripheral arterial gasometry is essential for the etiological diagnosis and consequently for treatment, as enabling to differentiate between CCP by alveolar hypoventilation and CCP by alveolar hyperventilation. The distinction is all the more important that with an identical hypoxia, acidosis increases the average pressure of the pulmonary artery and alkalosis decreases it.
