Resynchronisation Therapy of Right Ventricle in Pulmonary Arterial Hypertension

Not Applicable

• Conditions: Pulmonary Arterial Hypertension

• Registration Number: NCT01905189
• Lead Sponsor: University Hospital, Caen

Brief Summary

Pulmonary arterial hypertension is a disease characterised by pathological changes in the pulmonary arteries leading to a progressive increase in pulmonary vascular resistance and pulmonary artery pressure. Right ventricular failure is the main cause of death in patients with pulmonary arterial hypertension, and the ability of the right ventricle to adapt to the progressive increase in pulmonary vascular resistance associated with changes to the pulmonary vasculature in pulmonary arterial hypertension is the main determinant of a patient's functional capacity and survival.

Right ventricular dyssynchrony was present in a substantial proportion of patients with pulmonary arterial hypertension and this dyssynchrony adversely affected right ventricular function.
