Safety and Effectiveness of Left Bundle Branch Area Pacing Versus Conventional Cardiac Resynchronization Therapy in Heart Failure

Summary

This study will compare two different methods to pace the heart to treat heart failure including: The current standard method of implanting a pacing lead in a vein on the surface of the left lower chamber of the heart (left ventricle) to deliver heart failure therapy. This method is called Cardiac Resynchronization Therapy (CRT). The other method is using a lead implanted in the Left Bundle Branch Area (LBBA) of your heart. This method is called Left Bundle Branch Area Pacing or LBBAP.
