Summary

Pulmonary Veino Occlusive Disease (PVOD) is a rare form of pulmonary arterial hypertension, characterised by a poor prognosis. Recent studies demonstrated that heritable form of pulmonary veino occlusive diseaseis due to bi-allelic mutations in EIF2AK4 gene. heritable pulmonary veino occlusive disease is an autosomal recessive disease. In the french referal center of severe PH, ulmonary veino occlusive disease patients carriers of bi-allelic mutations in EIF2AK4 gene were identified. Genetic counselling in these families allowed to identified herozygous carriers of a single mutation in EIF2AK4 gene. However, to date, nothing is known about the risk of these persons of developping pulmonary diseases. It appears essential to determine the clinical, functional, echocardiographic and radiologics characteristics of these persons, and their risk of developping Pulmonary veino occlusive disease

Interventions

OTHER

Screening of adult without diagnosis of PH carrying an heterozygous EIF2AK4 mutation.

will be performed : a clinical evaluation (dyspnea assessed by New York Heart Association functional class (I-IV), signs of right heart failure), a 6min walk test, a Computerized Tomography scan of the chest, an electrocardiogram, an echocardiography (measurement of the velocity of tricuspid regurgitation, measurement of Tricuspid Annular Plane Systolic Excursion (TAPSE) and Tei index, pericardial effusion, dilatation and hypertrophy of the right ventricle), an abdomina ulstrasound, a stress Test (ventilation oxygen peak and ventilation oxygen specific, minute ventilation, dead-space ventilation / dead space, ventilatory reserve, alveolar-arterial gradient, pulse oxygen, PaO2), a lung function tests and measurement of Diffusing capacity or transfer factor of the Lung for Carbon mOnoxide (DLCO) and Nitric Oxide (DLNO), and a blood sample.
