All 28 patients had symptomatic right ventricular failure and underwent heart-lung transplantation in our institution. Phydiopathologie a first study, we investigated PH screening with echocardiography in patients with advanced lung disease.

The RV was evaluated with parameters derived from pressure-volume loops, echocardiography, right heart catheterism and with circulating biomarkers.

However, none of those treatments cure the disease and new drugs are still needed. As pulmonary vascular cells exhibit a cancer-like hyperproliferative and apoptotic-resistant phenotype in PAH, we hypothesized that the activation of pulmonary vascular NMDARs may contribute to the vascular remodeling leading to PAH.

In a third study, we highlighted that a strong relationship between ventricular-arterial coupling and functional and molecular plasticity of the pressure overloaded right ventricle. These data provide a strong rational to develop specific biomarkers to evaluate tissue physiolathologie of the right ventricle and determine their clinical implications. The first model was a systemic-to-pulmonary shunt SHUNT between the aortic arch and the pulmonary trunk.

Therefore, we analyzed the role of endothelial dysfunction in the control of two types of altered immune responses: However, the pathophysiology of the transition from adaptive to maladaptive phenotypes remains unclear; and identification of RV therapeutic targets and noninvasive methods for its evaluation remains to developed.

A wide review of anatomic, embryologic and physiologic concepts was performed to help for the understanding of parameters of RV evaluation; then published and ongoing original studies were presented. It is suggested that mitochondrial metabolism is impaired in right ventricular failure.

La BPCO appartient au champ des maladies broncho-pulmonaires obstructives. It is also present in peripheral cells, including aortic and cerebral vascular cells, and promotes their proliferation. We characterized right ventricular changes during acute phgsiopathologie and pressure physioathologie and after hemodynamic restauration in a large animal model of chronic thromboembolic PH.

Mechanisms that involve the formation and persistence of thrombus leading to a fibrous vascular remodeling remain unknown. The aim of this thesis was to evaluate non-invasive screening of PH with echocardiography and to study the pathophysiology of acute right heart failure in the setting of chronic PH by performing precise phenotyping of a new large animal bronchitw.


Molecular pathways involved in both mechanisms are currently studied to find new targeted therapeutics. Right ventricular response to exercise or to pharmacological stress has been poorly reported in pulmonary hypertension.

Similarly, tyrosine kinase inhibitors have shown efficacy in PAH management but associated with severe adverse events as cardiac toxicity.
