Comparative StudyComparison of early and late outcomes of TAVI alone compared to TAVI plus PCI in aortic stenosis patients with and without coronary artery disease.
To assess the safety and effectiveness of performing percutaneous coronary intervention (PCI) before transcatheter aortic valve implantation (TAVI). ⋯ Performing PCI before TAVI in high-risk elderly patients with significant CAD and severe AS is feasible and safe. This combined treatment approach did not increase the periprocedural risk for complications or the all-cause mortality.

Comparative StudyProlonged high-pressure is required for optimal stent deployment as assessed by optical coherence tomography.
Optimizing stent deployment is important for both acute- and long-term outcomes. High-pressure balloon inflation is the standard for coronary stent implantation. However, there is no standardized inflation protocol. We hypothesized that prolonged high-pressure balloon inflation until stabilization of inflation pressure is superior to a rapid inflation/deflation sequence for both stent expansion and strut apposition. ⋯ These data demonstrate that prolonged inflation is superior to a rapid inflation/deflation technique for both stent expansion and strut apposition. We recommend for routine stent deployment a prolonged inflation protocol as described above to optimize stent deployment.
