Effects of Right Ventricular Pacemaker Lead Position Assessed by MRI

Not Applicable

• Conditions: Late Complication From Cardiac Pacemaker Implantation

• Registration Number: NCT01682239
• Lead Sponsor: Medical University of Vienna

Brief Summary

Chronic right ventricular apical pacing has been associated with negative hemodynamic effects. Clinical outcome of right ventricular pacing can be influenced by multiple factors. An important factor seems to be optimal lead positioning. Data regarding left ventricular function impaired by lead positioning is insufficient. The aim of the present study therefore is to compare right ventricular apical pacing (RVAP) with right ventricular septal pacing (RVSP). Outcome measurements are echocardiographic features, magnetic resonance imaging and clinical outcome.

Primary Outcome Measures

Name	Time	Method
Ejection Fraction	6 month	As primary endpoint the difference of ventricular function in both groups will be taken. Therefore the Ejection Fraction is measured in cardiac MRI and Echocardiography. There may be a different development of contraction, whether the lead is placed in the ventricular apex or the ventricular septum.
