[Long-term results of aortocoronary bypass. 1. Clinical aspects].

Eighty patients undergoing one or several aorto-coronary bypass graft procedures had longterm clinical and arteriographic follow-up (mean follow-up period of two years, extremes 1 and 6 years). The indication fort operation in these patients was unstable angina in 39 (49%), threatened infarction in 16 (20%), Prinzmetal's angina in 8 (10%), and stable but incapacitating angina in 17 (21%). Significant lesions involved the three coronary trunks in 49 cases, two trunks in 25 cases, and one trunk in 6 cases. The longterm clinical results were excellent in 65% of cases, and fair in 26%; the procedure failed in 9% of cases. Angina pectoris either disappeared or improved in 96% of cases. After operation, myocardial infarctions occurred in 11 cases (14%), 7 of which were early and 4 late with a delay of 1 to 4 years. The pre-operative cardiac failure disappeared or decreased in 13 cases out of 16. Finally the quality of the clinical results does not seem to be influenced by the various indications for operation with the exception of Prinzmetal's angina, where the results have been excellent in all cases (8 cases out of 8).

[Long-term results of aortocoronary bypass. 2 Angiographic aspects].

Follow-up arteriograms carried out between one and six years (mean follow-up period two years) in 80 cases of aorto-coronary bypass graft procedures showed a good correlation between the quality of the clinical results obtained -- as detailed in the first part of this article -- and a larger proportion of patent grafts: 82% of 130 grafts had remained patent, and 94% of patients have all or some of their grafts patent. Late occlusion of the grafts is rare, and does not appear to be influenced by abnormalities of the graft found at early follow-up, these abnormalities being fairly stable. These follow-up have especially shown the good correlation between the quality of the clinical results and the functional status of the coronary network in the long term, a function not only of the permeability of the grafts which have been carried out, but also of the complete or incomplete correction of the lesions of the three coronary trunks. Such a complete procedure which was carried out or could have been carried out in only 30% of the total patients, was then successful in 94% undergoing it. The clinical results should therefore lead us to carry out operations which remove the lesions as completely as possible.

[Hemodynamic diagnosis of tricuspid insufficiency].

An analysis and comparison has been made of the value in the diagnosis and assessment of the degree of tricuspid incompetence of the following: the pressure curves of the right side of the heart, intracardiac phonocardiography and the venous dilution curves of ascorbic acid. The study was carried out on 49 patients, and a comparison made with selective right ventricular cineangiography, which was chosen arbitarily as a baseline. The information from the pressure curves and from intracardiac phonocardiography often contains errors of ommission or commission, but that from the venous dilution curves of ascorbic acid came out as the most reliable; these curves do tend to overestimate the degree of regurgitation, but they still allow us to reserve selective cineangiography, which is quantitatively a more precise method, for those cases in which the curves indicate a particularly severe degree of tricuspid incompetence.
