Bottom Line: The need for a patient to have a permanent pacemaker implanted while hospitalized after undergoing a transcatheter aortic valve replacement is a complication associated with worse survival and increased risk of more time spent in the hospital then and in the future.
Why The Research Is Interesting: Transcatheter aortic valve replacement (TAVR) is a common treatment for patients with severe narrowing of the aorta. Complications are a concern, in particular TAVR-related conduction disturbances and the need to have a permanent pacemaker implanted. Research on the impact of having a permanent pacemaker implanted has been inconsistent.
