Why the study?
Does isolated LBBB affect biventricular volumes and ejection fraction in adults without overt cardiovascular disease?
Does isolated LBBB affect biventricular volumes and ejection fraction in adults without overt cardiovascular disease?
Isolated LBBB is associated with greater LV volumes and reduced LVEF even without overt cardiovascular disease, which is important for interpreting imaging studies.
No takes yet. Share an insight, caveat, or question.
Isolated LBBB warrants caution in CMR interpretation of LV volumes and LVEF; leaves open causality and outcomes in prospective studies.
Akhtari et al. (2018) studied this question.
