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

open access: yesCatheterization 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.

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

open access: yesCatheterization 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?

open access: yesCatheterization 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.

Around and Through: Successful Mitral Paravalvular Leakage Closure Using Both Anterograde and Retrograde Approaches

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Paravalvular leak (PVL) is a recognized complication after surgical mitral valve replacement and may cause heart failure, pulmonary hypertension, or hemolysis when moderate or severe. Although redo surgery is the definitive treatment, it carries substantial risk in elderly patients or those with multiple prior cardiac surgeries.

Single Centre Experience With the Balloon‐Expandable Myval Transcatheter Aortic Valve System in Patients With Bicuspid Anatomy: 1 Year Follow‐Up

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy remains challenging due to anatomical complexity and limited trial data. New‐generation balloon‐expandable valves, such as Myval, require further evaluation in this subgroup.

Pd(II)‐Catalyzed Strategies for the β‐Arylation of α‐Amino Acids: An Overview

open access: yesChemistry – A European Journal, EarlyView.
The graphical abstract summarizes the review “Pd(II)‐Catalyzed Strategies for the β‐Arylation of α‐Amino Acids: An Overview”, highlighting representative Pd(II)‐catalyzed methods for the β‐arylation of α‐amino acids. Key mechanistic features, substrate diversity, and synthetic relevance of these transformations are showcased. Abstract Metal‐catalyzed C─
