Heart failure & cardiomyopathies

Left Bundle Branch Pacing vs Left Ventricular Septal Pacing vs Biventricular Pacing for Cardiac Resynchronization Therapy

JACC Clin ElectrophysiolPublished Prospective observational cohort study

Authors' conclusion

In patients undergoing CRT, LBBP was associated with improved outcomes compared with LVSP and BIVP, while outcomes between BIVP and LVSP are similar.
