[Genetic counseling in cardiology].

Progress in the recognition of genetic factors implicated in cardiovascular diseases is now such that it poses the question of how to integrate these data into a clinical perspective. To be able to give the most relevant information to the patient and his family, and to use this information to optimise the medical management have become new objectives. This can only be achieved with the close collaboration between cardiologist and the genticist, who knows the legislative framework which governs the performance of genetic tests. During the genetic counselling consultation, and after time for compiling information on the disease and the family, the geneticist gives the most suitable information on the genetic nature of the disease. Depending on the illness, cardiological investigation for the relatives could be advocated. The performance of a molecular test is then discussed, as a function of its feasibility, relevance and the wishes of the patient. The complexity of the medical and psychological stakes varies according to the situation (presymptomatic diagnosis, prenatal diagnosis, diagnostic test, prognostic test) and the condition. In all cases, strict rules perfectly laid down by legislation must be respected, in such a way as to protect the patient from possible unfavourable repercussions and to assure him of better medical management and a greater well-being.
