Trial in Cardiac Resynchronization Therapy (CRT): Right Ventricular Apex Versus High Posterior Septum

Haukeland University Hospital

Status and phase: Unknown; Phase 2

Conditions: Heart Failure

Treatments: Device: CRT in heart failure; Right ventricular apex v.s. high posterior septum

Study type: Interventional

Funder types: Other

Identifiers

NCT01035489

2009/1991

Details and patient eligibility

About

In heart failure patients we hypothesised that right ventricular high posterior septum is superior to right ventricular apex in CRT and DDD pacemaker. In two separate trials we prospectively randomized the right ventricular lead placement to find evidence of differences in heart failure symptoms (NYHA-class), 6 minute hall walk and echocardiographic measurements of reverse remodelling and dyssynchrony.

Enrollment: 85 estimated patients
