Final answer:
TAVR is often associated with a higher incidence of pervalvular leaks but has lower risks of AKI, afib, and major bleeding compared to SAVR. SAVR may involve greater risk of postoperative complications due to its more invasive nature and the use of cardiopulmonary bypass.
Step-by-step explanation:
Transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) are both procedures used to treat aortic stenosis. When comparing the two in terms of pervalvular leak, acute kidney injury (AKI), atrial fibrillation (afib), and bleeding risk, there are some notable differences.
- Pervalvular Leak: TAVR may have a higher incidence of pervalvular leaks compared to SAVR due to the nature of the procedure and the fit of the valve.
- AKI: The risk of AKI is generally lower in TAVR compared to SAVR, likely due to the less invasive nature of TAVR and reduced manipulation of the aorta.
- Afib: SAVR has been associated with a higher risk of postoperative afib compared to TAVR, which may be related to surgical trauma or the use of cardiopulmonary bypass during SAVR.
- Bleeding Risk: TAVR typically presents a lower risk of major bleeding compared to SAVR, in part due to the minimal invasiveness of the procedure and the reduced need for anticoagulants like Rivaroxaban (Xarelto), Dabigatran (Pradaxa), Apixaban (Eliquis), Heparin (various), and Warfarin (Coumadin).
