Prognostic significance of somatic mutations in myeloid cells of men with chronic heart failure – interaction between loss of Y chromosome and clonal haematopoiesis

European Journal of Heart Failure, EarlyView.
Abstract Aims Age‐associated clonal haematopoiesis of indeterminate potential (CHIP) has been linked to increased incidence and worse prognosis of chronic heart failure (CHF). CHIP arises from somatic mutations in haematopoietic stem and progenitor cells. Mosaic loss of Y chromosome (LOY), the most common somatic mutation in male blood cells, increases

A U‐shaped relationship between left ventricular ejection fraction and risk of worsening heart failure

European Journal of Heart Failure, EarlyView.
A U‐shaped relationship between left ventricular ejection fraction (LVEF) and clinical outcomes. A U‐shaped relationship can be observed between LVEF, the primary outcome, and the cardiovascular‐related outcomes, including cardiovascular death and the risk of worsening heart failure (HF).

Cardiac Imaging for Assessing Low-Gradient Severe Aortic Stenosis

JACC: Cardiovascular Imaging, 2017
Up to 40% of patients with aortic stenosis (AS) harbor discordant Doppler-echocardiographic findings, the most common of which is the presence of a small aortic valve area (≤1.0 cm2) suggesting severe AS, but a low gradient (

Diagnostic Value of Computed Tomography Angiography for Detecting Bronchial Artery‐Pulmonary Artery Fistula in Patients With Hemoptysis and Findings Associated With Its Presence

iRADIOLOGY, EarlyView.
The computed tomography angiography (CTA) is a very effective tool for detecting bronchial artery‐pulmonary artery fistula (BPF) in hemoptysis patients, the CTA and digital subtraction angiography (DSA) had high consistency in detecting the BPF in our finding.

Versatile and Highly Efficient MRI Simulation of Arbitrary Motion in KomaMRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To extend the KomaMRI simulator with motion capabilities that enable the simulation of both simple, parametrizable motion patterns and arbitrarily complex spin trajectories. Additionally, we introduce a novel file format for storing and sharing dynamic digital phantoms.

Coronary Artery Blood Flow Imaging Using 3D Flow MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.

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 ...

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.
