Why the study?
TAVI for prosthetic valve dysfunction is frequently associated with suboptimal echocardiographic outcomes, and the effect of anticoagulation on preserving valve function is not well understood.
Does anticoagulation improve valve hemodynamics in patients undergoing transcatheter valve-in-valve implantation?
Does anticoagulation improve valve hemodynamics in patients undergoing transcatheter valve-in-valve implantation?
Anticoagulation after valve-in-valve TAVI may improve valve hemodynamics at 1 year, though further data are needed to confirm clinical benefits.
Does not support routine anticoagulation post valve-in-valve TAVI for hemodynamic benefit; leaves open need for randomized trials.
Background: Transcatheter aortic valve implantation (TAVI) for prosthetic valve dysfunction is frequently associated with suboptimal echocardiographic outcomes. The effect of anticoagulation on preserving valve function is not well understood. Methods: ), and dimensionless index over time. Results: = .104) at 1-year post-TAVI. Conclusions: Anticoagulation postvalve-in-valve TAVI may lead to lower mean gradients and peak velocities at 1-year follow-up. More data are needed to understand its impact on nonflow-dependent indices and clinical outcomes.
