Cardiac Resynchronization Therapy in Pulmonary Hypertension (CRT in PH)
September 19, 2017 updated by: Dr. Daniel P Morin, MD MPH FHRS
This study is being conducted to determine whether patients with advanced pulmonary hypertension when treated with cardiac resynchronization therapy improve hemodynamically and/or receive clinical benefit.

Detailed Description
This study aims to determine whether stimulating earlier activation of the failing right ventricle in pulmonary hypertension reduces the effects of interventricular dependence in human subjects, thereby improving overall cardiac function and symptoms in patients with pulmonary hypertension and right ventricle failure with NYHA Class 3-4 symptoms.

Experimental: Arms
Pacing wires used to stimulate ventricles in a synchronous matter
|
A CRT device sends small electrical impulses to both lower chambers of the heart to help them beat together in a more synchronized pattern.
