Valve-in-Valve Implantation of Medtronic CoreValve Prosthesis in Patients With Failing Bioprosthetic Aortic Valves: Mid-term Outcomes From the Italian CoreValve Clinical Service Project - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/35100553/
Objectives: We evaluated the acute and two-year safety and efficacy of using the Corevalve, Evolut R, and Evolut PRO valves for treating failed surgical bioprosthesis from the Italian CoreValve Clinical...
Conclusions: This real-world nationwide analysis demonstrates the acute and longer-term safety and efficacy of using the self-expanding Medtronic THV for ViV-TAVR.
Outcomes in Patients With Asymptomatic Aortic Stenosis (from the Evolut Low Risk Trial)

Transcatheter aortic valve implantation (TAVI) has comparable outcomes with surgical aortic valve replacement (SAVR) in symptomatic patients with severe aortic stenosis, including those at low risk for surgery. Less is...
Speckle tracking echocardiographic assessment of left ventricular function by myocardial strain before and after aortic valve replacement
Source : https://www.j-saudi-heart.com/jsha/vol33/iss4/16/
Background & Objectives: In patients of aortic stenosis and regurgitation, pressure and volume effects on left ventricular function are occult and missed by routine echocardiography markers like ejection fraction (EF)....
Relevance: In patients of aortic stenosis and regurgitation, pressure and volume effects on left ventricular function are occult and missed by routine echocardiography markers like ejection fraction (EF). Speckle tracking analysis by measuring global longitudinal strain and global circumferential strain seems to ascertain this occult LV...
Transcatheter aortic valve implantation in pure aortic regurgitation: Hemodynamic and echocardiographic findings in bioprosthesis vs. native valve
Source : https://onlinelibrary.wiley.com/doi/10.1002/ccd.30082
Objective The objective of this study is to compare hemodynamic and echocardiographic findings between valve-in-valve (VIV) and native-valve (NV) patients submitted to transcatheter aortic valve imp...
Conclusions: Successful TAVI induces a striking hemodynamic impact with major structural (reverse remodeling) consequences in patients with pure AR caused by both bioprosthesis degeneration or NV disease. In the immediate postrelease phase, VIV patients might exhibit a more pronounced early LV contractile and structural benefit.
One-year outcome after transcatheter aortic valve replacement for aortic regurgitation: A single-center study - PubMed

Conclusions: In high-risk patients undergoing transapical TAVR for AR, the use of the J-Valve is safe, and effective TAVR should be considered as a reasonable option for high-risk patients with pure AR.
