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

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.
