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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Resynchronisation Therapy of Right Ventricle in Pulmonary Arterial Hypertension
Study Start Date : July 2013
Estimated Primary Completion Date : June 2014

Arm Intervention/treatment
Experimental: Hemodynamic study, cardiac pacing
We propose to study the hemodynamic response to a temporary atrio-dual right ventricular stimulation in pulmonary arterial hypertension subjects.Patients will be is own comparator.
Procedure: Resynchronization therapy of right ventricle
Right atrio-ventricular resynchronization therapy combined with right intra-ventricular resynchronization therapy

Primary Outcome Measures :
  1. cardiac index measured during right catheterization [ Time Frame: After two minutes of right stimulation ]
