Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

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‐

Surgical Versus Transcatheter Aortic Valve Replacement in Patients Aged >60 Years With Bicuspid Valve Stenosis: A Time‐to‐Event Data Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The role of transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve stenosis requires further evaluation, particularly as its use has become comparable to surgical aortic valve replacement. We sought to compare midterm outcomes

Enabling automated device size selection for transcatheter aortic valve implantation [PDF]

, 2019
The number of transcatheter aortic valve implantation (TAVI) procedures is expected to increase significantly in the coming years. Improving efficiency will become essential for experienced operators performing large TAVI volumes, while new operators ...

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 ...

Prosthetic Valve Endocarditis After Aortic Valve Replacement With Bovine Versus Porcine Bioprostheses

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Whether a bovine or porcine aortic valve bioprosthesis carries a higher risk of endocarditis after aortic valve replacement is unknown. The aim of this study was to compare the risk of prosthetic endocarditis in patients undergoing aortic ...

Balloon‐Expandable Versus Self‐Expanding Valves in Low‐Flow, Low‐Gradient Aortic Stenosis: Does Valve Type Matter?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The optimal choice between balloon‐expandable (BE) and self‐expanding (SE) transcatheter heart valves (THVs) in patients with low‐flow low‐gradient aortic stenosis (LFLG AS) undergoing transcatheter aortic valve replacement (TAVR) remains unclear.

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.

Excessive Ostial Stent Protrusion: Evaluation of Management Strategies and Clinical Outcomes of the Side Flap Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Backgrounds Accurate stent positioning in aorto‐ostial lesions remains challenging due to complex three‐dimensional anatomy, lack of optimal fluoroscopic projections, and high rates of geographic miss. Stent overhang impairs guide catheter re‐engagement and complicates future revascularization.
