Outcome with an impaired left ventricle: can a good risk be predicted?

Whether a case of mild left ventricular impairment is still compatible with the physical and mental capacity to fly is considered, the question is: un de venis? quo vadis? That is, what is the rate of evolution? To define such a rate, two measurements separated by a sufficient delay are necessary. Th e left ventricle should be checked every 6 months later with great care. In a borderline situation the quality of evaluation and the qualification of the observers are of prime importance. If it is not possible to predict ind ividual risk, but classification of patients into low, intermediate and hig her risk groups is feasible and may be carried out annually.
