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

Table 1 Factors that patients prioritize

Left bundle branch-CRT	Biventricular-CRT
Typical LBBB with NICMP	LBBB with ischemic cardiomyopathy with septal scar
Pacing induced cardiomyopathy	nonspecific interventricular conduction delay with heart failure with reduced ejection fraction
Masquerading bundle branch block with NICMP	Structural heart disease with septal scar e.g. cardiac sarcoidosis, myocardial tuberculosis, hypertrophic cardiomyopathy, inherited cardiomyopathy

CRT: Cardiac resynchronization therapy; LBBB: Left bundle branch block; NICMP: Nonischemic cardiomyopathy.
