Left bundle branch pacing cardiac resynchronization therapy vs biventricular pacing cardiac resynchronization therapy–time to write a requiem for biventricular pacing-cardiac resynchronization therapy

Figure 1 The criteria for determining selective left bundle branch area capture during left bundle branch area pacing. The blue dotted line represents a hypothetical left bundle branch area pacing lead. LV: Left ventricular; LVEF: Left ventricular ejection fraction; NYHA: New York Heart Association.

Figure 2 The potential advantages of left bundle branch area pacing based cardiac resynchronization therapy over biventricular cardiac resynchronization therapy based on randomized clinical trial’s and meta-analyses. LBBP: Left bundle branch pacing; LVSP: Left ventricular septal pacing.
