Abstract

This paper describes a case of patient post-TAVI who developed Left Septal Fascicular Block (LSFB) and Right Bundle Branch Block (RBBB). This combination has not been previously reported and must be actively sought out, given the possible increased risk of complete atrioventricular block and sudden cardiac death. RBBB following transcatheter aortic valve replacement is rare and is associated with complete atrioventricular block and permanent pacemaker implantation. LFSB on ECG may be a surrogate maker of diffuse conduction systemic damage following TAVI. Therefore, there should be a low threshold for permanent pacing in patients who develop new RBBB and LSFB post-TAVI.
