Repositioning and optimization of left ventricular lead position in non-responders to Cardiac Resynchronization Therapy is associated with improved ejection fraction, lower NT-ProBNP values and less heart failure symptoms
BackgroundObservational data suggests that an anterior or apical left ventricular (LV) position in Cardiac Resynchronization Therapy (CRT) is associated with worse outcome and higher likelihood of “non-response”. It is not known whether the benefits of optimizing LV lead position in a second procedure outweighs the procedural risks.ObjectiveTo evaluate the clinical effects of LV lead repositioning
