[Right intraventricular biopsy. Indications and results. 116 cases].

The indications for endomyocardial biopsy were evaluated from 116 consecutive cases. The diagnostic value of this invasive but well tolerated procedure was in agreement with data from the literature. An accurate diagnosis, unforseeable in 8% of the patients, was established in 12%.

[Distribution of lactate dehydrogenase isoenzymes in human myocardium obtained from endomyocardial biopsies].

The distribution of lactate dehydrogenase and its isoenzymes in myocardial tissue obtained by biopsies from within the right ventricle can be studied by electrophoresis in a similar manner to that for making serum determinations. Results are comparable to radioimmunologic dosing (Peters) and microelectrophoresis (Schultheiss) and complete the findings obtained from the histological study of biopsied fragments.

[Histological aspects of congestive cardiomyopathy caused by alcohol. Comparison with so-called primary cardiomyopathies].

The endoventricular biopsies of nine patients with alcoholic congestive cardiomyopathy were studied under the light microscope and under the electron microscope. These were compared with the results of nine cases of primary congestive cardiomyopathy, at a similar clinical stage. In the absence of specific signs, the overall appearance on both light and electron microscopy is sufficiently suggestive to allow differentiation of the two forms of cardiomyopathy.

[Right endoventricular biopsy using the femoral percutaneous approach: a simple procedure, harmless, reliable and repetitive. Modification of the Konno technic].

The technique of right endoventricular biopsy by femoral percutaneous path is described based on 300 incident-free samples. Ability to multiply and then repeat sampling supports a method which can be performed at the same time as examination of the conduction channels. This is of diagnostic, prognostic, therapeutic and research interest.
