Endomyocardial Fibrosis Associated With Hypereosinophilic Syndrome: Diagnostic and Management Insights From a Case Report

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Endomyocardial fibrosis (EMF) is a rare form of restrictive cardiomyopathy associated with eosinophilic disorders, characterized by apical subendocardial fibrosis and thrombus formation. Cardiac magnetic resonance (CMR) provides a comprehensive, noninvasive evaluation, enabling diagnosis, assessment of disease activity, and guidance of therapy.

Commissural Misalignment Following Valve‐in‐Valve Transcatheter Aortic Valve Implantation

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data on commissural misalignment (CMA) during valve‐in‐valve transcatheter aortic valve implantation (ViV‐TAVI) for valve failure after surgical aortic valve replacement (SAVR) is scarce. Aims To study the impact of CMA on clinical and hemodynamic outcomes following ViV‐TAVI for failed SAVR.

Growth differentiation factor‐15 and N‐terminal pro‐BNP in acute heart failure with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 888-899, April 2025.
Abstract Aims Heart failure with preserved ejection fraction (HFpEF) continues to be an increasingly common health problem associated with a high mortality rate. Elevated levels of Growth differentiation factor‐15 (GDF15) and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) are reportedly associated with poor clinical outcomes in a broad range of ...
