[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.

New electron-capture gas-liquid chromatographic method for the determination of mexiletine plasma levels in man.

A method for the determination of mexiletine in human plasma by gas-liquid chromatography with electron-capture detection is described. Plasma samples are extracted at pH 12 with dichloromethane after addition of the internal standard, the 2,4-methyl analogue of mexiletine. A derivative is obtained using heptafluorobutyric anhydride; according to gas chromatography-mass spectrometry it is a monoheptafluorobutyryl compound. The minimum detectable amount of mexiletine is 5 pg. Accurate determinations of human plasma levels were performed after oral or intravenous treatment.

[Constrictive fibrous endocarditis. Surgical treatment].

An anatomo-clinical entity, fibrous constrictive endocarditis can betreated srugically, and we carried out this procedure for the first time in 1971, since when we have used it seven times; it consists of an internal stripping of one or both centricles, with removal of one or both the mitral and tricuspid valves. The results were encouraging in the first two cases, and so good in the succeeding ones that this endocardial resection could be put forward as the treatment of choice for a condition whose aetiology is still unclear.

The surgical treatment of constrictive fibrous endocarditis.

Constrictive fibrous endocarditis is a pathological entity described by Loëffler in 1936. Its etiology is unknown. The clinical course is characterized by an evolution towards cardiac insufficiency leading rapidly to a fatal outcome. Moderen paraclinical investigations are necessary to assess the diagnostic. Caridac catheterization brings the proof of adiastole and angiogardiography reveals the shape of amputation of the ventricle with auriculoventricular regurgitation. The operative procedure consists of resection of the ventricular fibrosis including the valves and auriculo-ventricular valve replacement by a prosthetic valve. The disease affects both Caucasians and Negros. Our experience includes 5 cases. The indications for operation and their results are discussed.

Emergency myocardial revascularization.

From 1969 to 1975, 175 patients with acute coronary insufficiency underwent emergency saphenous vein aorto-coronary bypass grafting (SVBG). The patients were divided into two groups: group I, unstable angina (165 patients) and group II, acute evolving myocardial infarction (ten patients). In group I, the hospital mortality was 8-4%, the incidence of post-operative myocardial infarction was 10-3%. Long-term follow-up was obtained for an average of 25 months, functional improvement was definite in the majority of the patients and actuarial survival curves show 87% patients alive at the end of 48 months. In group II, the hospital mortality was 30%; seven of ten patients had good results.

[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.
