Immediate Outcomes of Aortic Valve Neocuspidization with Glutaraldehyde-treated Autologous Pericardium: a Multicenter Study

Brazilian Journal of Cardiovascular Surgery
Objective: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. Methods: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 ...

Early Multicenter Outcomes of Dedicated Transcatheter Aortic Valve Replacement for Left Ventricular Assist Device‐Associated Pure Aortic Regurgitation

Artificial Organs, Volume 50, Issue 10, Page 1427-1433, October 2026.
LVAD‐associated aortic regurgitation impairs circulatory support, with limited surgical and off‐label options. In a multicenter registry (n = 30), the AR‐dedicated JenaValve Trilogy TAVR eliminated AR, achieving 96.7% (29/30) technical success and 93.3% (28/30) device success (VARC‐3), with 3.3% (1/30) 30‐day mortality.

Physiopathological mechanisms of severe low gradient paradoxical aortic stenosis

, 2020
Assessment of aortic stenosis severity is challenging in the current practice. Paradoxical low gradient severe aortic stenosis is defined by discordance between transvalvular gradient and valve area despite a preserve cardiac function.

Nucleic Acids as Emerging Regulators of Calcium Phosphate Biomineralization

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Calcium phosphate biomineralization has traditionally been considered a protein‐regulated process. This review highlights the emerging role of nucleic acids, which interact with mineral phases through adsorption, coprecipitation, and templating, thereby influencing crystal nucleation and growth.

Severe mitral stenosis as a cause of paradoxical low-flow, low-gradient severe aortic stenosis: an explorative study on hemodynamics and outcomes

Frontiers in Cardiovascular Medicine
BackgroundAortic stenosis (AS) and mitral stenosis (MS) are valvular heart diseases that may present concomitantly, particularly in regions where rheumatic heart disease remains prevalent.

Diagnostic Value of Aortic Valve Calcification Levels in the Assessment of Low-Gradient Aortic Stenosis

JACC: Cardiovascular Imaging
Chez les patients présentant une sténose aortique (SA) à faible gradient et un faible débit transvalvulaire, l'échocardiographie de stress à la dobutamine (DSE) est recommandée pour déterminer la gravité de la SA, alors que le degré de calcification de la valve aortique (CVA) est censé être corrélé à la gravité de la SA selon les directives européennes

Prevalence and prognostic implications of different aetiologies of low flow aortic stenosis

Cardiovascular Ultrasound
Background The prevalence and prognostic implications of low-flow (LF) aetiologies in aortic stenosis (AS) are unknown. This study aimed to characterize the specific causes of LF, their prevalence, and prognostic significance.
