[Cineangiocardiographic evaluation of mitral valve lesions. Validity of the method according to 100 angio-surgical correlations].

In order to assess their validity, the findings on left bidirectional cineventriculography have been compared with the operative findings in 100 patients with mitral valve disease. This method of investigation has been shown to be a reliable one for the precise and complete evaluation of mitral valve lesions. The information which it provides about the morphology and kinetics of the valve, the site of any calcification, the state of the suspensory apparatus, and the degree and cause of any mitral incompetence often has a decisive influence on the indications for surgery and the choice of operation.

[Catheterization in orificial aortic stenosis].

By virtue of its relative simplicity and its rapidity, the investigation of aortic stenosis recently perfected (and used with a satisfactory percentage of success and without important incident) deserves wide usage in haemodynamic and angiograpnic laboratories. Even if it does not always provide the solution to a particularly delicate problem, which is often of vital importance, it provides data which, modifiable and better used, should provide an adequate notion of the anatomical and physiopathological state in aortic stenosis.

[Evaluation of 2 years' experience with assisted circulation by diastolic counterpulsation].

The authors report their two years' experience of circulatory assistance by diastolic counter-pulsation with an intra-aortic balloon. This technique was used in 23 patients: 9 cases of cardiogenic shock due to acute myocardial infarction, 9 septal ruptures, 1 rupture of the papillary muscle of the mitral valve, 1 acute ventricular aneurysm, 2 high risk coronary arteriographies and 1 case of early post-infarction recurrent ischemia. It confirms the gravity of cardiogenic shock as, in spite of the frequent improvement in hemodynamic parameters under counter-pulsation, there was only one survivor. The efficacy is greater in cases of septal rupture, where the author obtained 3 survivors out of 6 operated cases. The security of the method and its innocuity permit one to carry out high risk coronary arteriography and extend the indications for circulatory assistance, to certain cases of unstable angina or early recurrent anginal following acute infarction.

[Classification of primary myocardiopathies according to cineangiographic and hemodynamic data].

Based on the data of high-speed, synchronous, biplane left cineventriculography and of haemodynamic examination, a physio-pathological classification for primary cardiomyopathies is put forward. Besides obstructive cardiomyopathies, three groups were individualized: hyperkinetic hypertrophic cardiomyopathy, hypokinetic hypertrophic and hypokinetic hypotrophic cardiomyopathies. The individuality of each group was discussed together with its eventual evolution from one the other. A better defined therapeutic attitude should result from this classification which therefore has a practical interest as well.
