title: [Principles of analysis and the value of coronaro-ventriculography in coronary surgery].
abstract: The examination which precedes any operation for revascularisation of the myocardium, coronaro-ventriculography, which has become a routine examination in specialised centres, should gain even further in reliability by anatomical examination of the vessels which it is used to study in vitro. A perfect knowledge of the distribution of the vessels (the numerous and sometimes unrecognised variations are a source of diagnostic error) and of the characteristics of the lesions (atheromatous in most cases) is essential for the accurate interpretation of a coronary arteriogram. Difficulties in analysis of the latter are numerous and the physician interpreting the examination should be fully aware of them before any decision regarding surgery is taken. Ventriculography routinely analyses, zone by zone, the contours of the left ventricle. In certain cases this segment study is associated with overall analysis of ventricular volumes and stroke fraction.
