Proteomic Pattern Associated With the Diagnosis of Chronic Thromboembolic Pulmonary Hypertension : PROTEO-CTEPH Study.
Chronic ThromboEmbolic Pulmonary Hypertension (CTEPH) is a rare but severe complication of pulmonary embolism (PE). CTEPH is evoked in patients with persistent dyspnea. According to international guidelines, symptomatic patients with perfusion defects on lung scan and Pulmonary Hypertension (PH)-likely transthoracic echo (TTE) must be evaluated in Pulmonary Hypertension (PH)-centers with right heart catheterism, to confirm or rule out the presence of precapillary Pulmonary Hypertension (PH), and precise the group of Pulmonary Hypertension (PH).
• Patient with a suspicion of Chronic thromboembolic pulmonary hypertension (CTEPH) with a combination of a perfusion lung scan and transthoracic perfusion scan and transthoracic echocardiography compatible with the diagnosis (according to French recommendations)
• Patients who require a right heart catheterization.
• Patient affiliated or entitled to a social security plan
• Patient having received informed information about the study informed about the study
