[Comparison of 14 methods for analysing left ventricle segmental kinetics by cineangiography].

Fourteen methods of analysing left ventricular wall motion on 30 degrees right anterior oblique left ventricular cineangiography were compared in 70 cases using a HP 9845 B computer. The methods included the superposition of the centres of gravity, perpendicular to the long axis, Leighton's Rickard 's, Ingels ' and others to determine the influence of the use of different anatomical points of reference on the results. A score was given for each programme in comparison with three groups of normal angiography, anterior infarction and inferior infarction limited to a single zone with no lesion on the opposite coronary artery.

[Complications of idiopathic mitral valve prolapse. Prevention and treatment].

Mitral valve prolapse is the most common form of heart disease, as it occurs in 4 to 6 per cent of the population. It has a benign course in the majority of cases, but 5 types of severe complication can occur in 15 per cent of cases. Mitral incompetence occurs in 14.
