Intra‐Annular Versus Supra‐Annular Self‐Expanding Valves for Valve‐in‐Valve TAVR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background A limitation of Valve‐in‐Valve (VIV) transcatheter aortic valve replacement (TAVR) is patient‐prosthesis mismatch (PPM), which is associated with worse quality of life and heart failure hospitalizations. As such, strategies to avoid PPM are desired. We compared the clinical and hemodynamic results of VIV TAVR with intra‐annular self‐

The Verification of Co‐Axiality of the Three Self‐Expanding Transcatheter Aortic Valve Systems According to the Difference in Shaft Spine

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Accurate bioprosthesis implantation depth during transcatheter aortic valve replacement (TAVR) is crucial for optimal outcomes. Self‐expanding valves (SEVs) have evolved delivery catheter designs, from a double spine shaft in Evolut PRO+ (PRO + ) to single spine in Evolut FX (FX) and non‐spine in Navitor, to improve access ...

Long‐Term Impact of Prosthesis‐Patient Mismatch After Transcatheter Aortic Valve Replacement in Patients With Small Aortic Annuli

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Prosthesis‐patient mismatch (PPM) remains common following transcatheter aortic valve replacement (TAVR) and is associated with worse clinical outcomes. PPM is of particular concern in small aortic annuli (SAA). Aims To compare the incidence, predictors, and long‐term impact of PPM in SAA TAVR.

Annular Ellipticity and Sizing Strategy in Transcatheter Aortic Valve Implantation: Independent or Combined Risk Patterns?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Elliptical annular anatomy has been considered a risk factor for adverse outcomes after TAVI, particularly paravalvular leakage (PVL). Prosthesis oversizing is thought to improve sealing, but the interaction between annular shape and sizing strategy remains unclear.

Transendocardial injection of expanded autologous CD34+ cells after myocardial infarction: Design of the EXCELLENT trial

ESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.
Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.
