Insights
Cardiac implantable electronic device (CIED) implantation is more common and occurs earlier after transcatheter aortic valve replacement (TAVR) than surgical aortic valve replacement (SAVR). Mitral valve interventions showed similar CIED implantation rates between surgical and transcatheter approaches within 180 days.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Health Services Research
Background:
- Valvular heart disease interventions frequently necessitate cardiac implantable electronic device (CIED) implantation due to conduction disturbances.
- Limited data exist on delayed CIED implantation, surgical comparisons, and outcomes after mitral valve interventions.
Purpose of the Study:
- To compare the incidence and timing of CIED implantation within 180 days following surgical and transcatheter aortic and mitral valve interventions.
Main Methods:
- Analysis of the Nationwide Readmissions Database (2016-2021).
- Identification of patients undergoing transcatheter aortic valve replacement (TAVR), surgical AVR (SAVR), transcatheter mitral valve replacement/repair (TMVR/TEER), or surgical MVR (SMVR).
- Evaluation of 180-day readmissions for CIED implantation using weighted analyses and Cox proportional-hazards models.
Main Results:
- Transcatheter patients were older with higher comorbidity burden.
- 180-day CIED implantation readmission rates were higher after TAVR vs. SAVR (2.33% vs. 0.88%; aHR 2.05), occurring earlier post-TAVR (median 10 vs. 49 days).
- TMVR/TEER and SMVR showed similar 180-day CIED implantation rates (1.66% vs. 1.71%). Aortic interventions had early CIED clusters, while mitral interventions showed a more even distribution.
Conclusions:
- CIED implantation readmissions occur earlier after aortic valve interventions compared to mitral valve interventions.
- TAVR had a higher incidence of CIED implantation readmissions than SAVR, but mitral interventions had comparable rates between surgical and percutaneous approaches.
- Findings inform rhythm monitoring strategies post-discharge following valve interventions.
Introduction:
Valvular interventions are associated with conduction disturbances requiring cardiac implantable electronic device (CIED) implantation. While prior studies have focused on early device implantation post-aortic interventions, less is known about delayed events, comparisons with surgical approaches, and outcomes following mitral interventions.
Objectives:
This study aimed to compare the incidence and timing of CIED implantation within 180 days after surgical and transcatheter aortic and mitral valve interventions.
Methods:
We analyzed the Nationwide Readmissions Database (2016-2021) to identify patients undergoing transcatheter aortic valve replacement (TAVR), surgical AVR (SAVR), transcatheter mitral valve replacement/repair (TMVR/TEER), or surgical MVR (SMVR). Readmissions within 180 days for CIED implantations were identified. Weighted analyses and Cox proportional-hazards models adjusted for demographics, comorbidities, and hospital factors were used.
Results:
Transcatheter patients were older and had a higher comorbidity burden than surgical patients. The 180-day readmission rate for CIED implantation was higher after TAVR versus SAVR (2.33% vs. 0.88%; adjusted HR 2.05, 95% CI 1.84-2.29, p < 0.001). Readmissions with CIED implantation occurred earlier following TAVR vs SAVR (median 10 days vs. 49 days). TMVR/TEER and SMVR had similar overall rates at 180 days (1.66% vs. 1.71%; HR 0.97, 95% CI 0.80-1.19, p = 0.80). Compared to aortic valve interventions, where readmissions with CIED implantation clustered early, readmissions with CIED implantation after mitral valve interventions were more evenly distributed over the first 6 months.
Conclusion:
Readmissions with CIED implantation within the first 6 months post-procedure occur earlier following aortic valve compared to mitral valve interventions. Whereas the incidence of readmission for CIED implantation was higher with TAVR compared to SAVR, readmission rates for CIED implantation were comparable over the first 6 months following surgical and percutaneous mitral interventions. These data have implications for the timing and duration of rhythm monitoring after discharge following valve interventions.
