Recent developments for surgical aortic valve replacement: the concept of sutureless valve technology [PDF]

, 2013
Aortic stenosis has become the most frequent type of valvular heart disease in Europe and North America and presents in the large majority of patients as calcified aortic stenosis in adults of advanced age.

Impact of Partial Echo on 4D Flow MRI: The Insight From Synthetic MRI

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3462-3475, June 2026.
ABSTRACT Purpose The aim of this study is to investigate the impact of the partial echo on 4D flow MRI sequences thanks to in silico coupled MRI‐CFD (computational fluid dynamics) simulations. Methods Two sequences are studied: one with a full echo (FE) and another using partial echo (PE) with an echo symmetry fraction of 0.75.

Delayed Time to Peak Velocity Is Useful for Detecting Severe Aortic Stenosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundTime to peak velocity (TPV) is an echocardiographic variable that can be easily measured and reflects a late peaking murmur, a classic physical finding suggesting severe aortic stenosis (AS).

Respiratory Motion‐Corrected Model‐Based 3D Water‐Fat MRA of the Thorax at 0.55 T

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3241-3252, June 2026.
ABSTRACT Purpose The goal of this study was to develop a 5‐min 3D MRA acquisition at 0.55 T with predictable scan time, 100% data efficiency, and robust water‐fat separation. Methods For full data efficiency, the proposed method combined self‐gating with retrospective motion correction while ensuring a predictable 5‐min scan time.

Mitochondrial Transplantation as a New Therapeutic Approach Against Cardiac and Renal Consequences in Male Rats With Myocardial Infarction

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim Myocardial infarction (MI) is one of the leading causes of death worldwide. MI is associated with cardiac structural and functional alterations. Among these, cardiac fibrosis may be significantly influenced by mitochondrial dysfunction. We sought to evaluate whether the injection of functional mitochondria from healthy muscle could improve

Long‐Term Outcomes of Transcatheter Aortic Valve Replacement in Low‐Flow Low‐Gradient Aortic Stenosis: A Reconstructed Time‐to‐Event and Multivariate Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background There are uncertainties regarding long‐term outcomes of low‐flow, low‐gradient (LFLG) severe aortic stenosis (AS) following transcatheter aortic valve replacement (TAVR). This study investigates long‐term outcomes of TAVR for high‐gradient (HG)

Addressing Key Limitations of Diastolic Function Assessment in Mouse Echocardiography by Enabling Robust Retrospective Analysis From a Standard Imaging View

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim Echocardiographic assessment of diastolic function in mice remains challenging because parameters translated from clinical practice are constrained by murine physiology. In particular, parameters derived from early (E) and late (A) transmitral filling velocities are frequently compromised by wave fusion at higher heart rates.

Calcification Characteristics of Low-Flow Low-Gradient Severe Aortic Stenosis in Patients Undergoing Transcatheter Aortic Valve Replacement

Cardiology Research and Practice, 2015
Low-flow low-gradient severe aortic stenosis (LFLGAS) is associated with worse outcomes. Aortic valve calcification patterns of LFLGAS as compared to non-LFLGAS have not yet been thoroughly assessed.

Cardiovascular Health in Women—Across the Lifespan

Clinical Endocrinology, Volume 104, Issue 6, Page 539-555, June 2026.
ABSTRACT Cardiovascular disease (CVD) remains the leading cause of mortality and morbidity among women worldwide. However, CVD continues to be perceived as a predominantly male issue. CVD in women therefore remains understudied, underrecognized and undertreated.

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 ...
