Patients undergoing transcatheter aortic valve implant may need a pacemaker after the TAVR device, but a new study suggests that right bundle branch block may predict the need for pacing. The data may have implications for device selection as some devices are seen as less likely to trigger the need for a pacemaker, a development that may move the needle in the robust but increasingly competitive market for TAVR.
Preclinical animal and cellular models are notoriously bad at predicting drug candidate toxicity in humans. Animal biology is often fundamentally different on this front than in humans, while cells in the lab can't be counted on routinely to replicate the bodily response.
