Valvular & structural heart diseaseCohort study
Contemporary Incidence and Procedural Volume of Transcatheter Aortic Valve Reintervention
- Retrospective cohort study
Authors' conclusion
In this study, annual volumes of both redo TAVR and TAVR explant continued to increase, particularly in recent years. Redo TAVR is frequently performed over 5 years from the index TAVR.
Study context
- Population
- Patients with prior transcatheter aortic valve replacement (TAVR) or SAVR undergoing subsequent TAVR or SAVR, US CMS data, January 2012 to June 2024410,720 TAVRs
- Participants
- 2,374 / 1,346 / 5,044 / 4,202
- Exposure
- Redo TAVR vs TAVR explant
- Redo TAVRn = 2,374
- TAVR explantn = 1,346
- Valve-in-valve (ViV) TAVRn = 5,044
- Redo SAVRn = 4,202
- Outcome
- Annual incidence and procedural volume of redo TAVR and TAVR explant
Main finding
As reported in the abstract
TAVR reintervention incidence and volume
| Group | Value | Since 2020 | Within 3 months of index TAVR (most common interval) | Share of reinterventions beyond 5 years | 1 to 2 years after index TAVR (most common interval) |
|---|---|---|---|---|---|
| Redo TAVR | 2374 events | 1518 | 410 of 2374 [17.3%] | 725 of 819 [88.5%] | |
| TAVR explant | 1346 events | 1007 | 259 of 1346 [19.2%] |
- Annual incidence of TAVR reintervention, 2019 to 2023
- 0.17% to 0.28%
Observational data: associations, not effects.
