Association of Clinical and Economic Outcomes With Permanent Pacemaker Implantation After Transcatheter Aortic Valve Replacement

Figure 1.. Cohort Selection All patients who underwent a transcatheter aortic valve replacement (TAVR) procedure from April 1, 2010, to March 31, 2015, were identified through the CorHealth TAVR registry. After excluding patients who had incomplete data, died during hospitalization, or had a permanent pacemaker (PPM) at baseline, patients were categorized into either the PPM group or the non-PPM group based on whether they had a PPM implanted during the index TAVR hospitalization. DAD indicates Canadian Institute for Health Information Discharge Abstract Database; IPTW, inverse probability of treatment weighting.

Figure 2.. Weighted Kaplan-Meier Curves Comparing Permanent Pacemaker (PPM) vs Non-PPM Groups Over the Entire Follow-up Period New PPM after transcatheter aortic valve replacement (TAVR) was associated with a longer duration of hospitalization and significantly greater all-cause mortality (A), all-cause readmission (B), and all-cause emergency department (ED) visits (C).
