VERMONT: Vessel Fractional Flow Reserve (vFFR) Assessment of Stenosis Severity: A Prospective Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vessel fractional flow reserve (vFFR) is an angiogram‐based technique validated in early studies; however, data on its real‐time diagnostic performance and integration into routine workflow remain limited. Aims The VERMONT study evaluated the diagnostic accuracy and time efficiency of real‐time vFFR versus conventional wire‐based ...

For Richer or For Poorer? Evidence from Indonesia, South Africa, Spain, and Venezuela [PDF]

, 2002
We analyze household income dynamics using longitudinal data from Indonesia, South Africa (KwaZulu-Natal), Spain and Venezuela. In all four countries, households with the lowest reported base-year income experienced the largest absolute income gains ...

Percutaneous coronary intervention in left main coronary artery disease with or without intravascular ultrasound: A meta-analysis.

PLoS ONE, 2017
This meta-analysis compared IVUS-guided with angiography-guided PCI to determine the effect of IVUS on the mortality in patients with LM CAD. Current guidelines recommend intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in ...

First evaluation of a novel pulsatile LVAD: Feasibility and haemodynamic impact in acute heart failure

ESC Heart Failure, EarlyView.
The pulsatile ventricular assist platform (pVAP) was connected to a membrane pump in six large swine models. The system, driven by a conventional intra‐aortic balloon pump console (IABP), was utilized to drain left atrial blood during systole and to eject the collected blood back into the ascending aorta during diastole.

Adaptation of right ventricular function following tricuspid transcatheter edge‐to‐edge repair

ESC Heart Failure, EarlyView.
Right ventricular remodelling following tricuspid transcatheter edge‐to‐edge repair. After T‐TEER, most patients either maintain or decrease their RVEF, while only a minority experience an increase. Patients with increased RVEF were associated with TR worsening and worse prognosis.

Phase chaos in the anisotropic complex Ginzburg-Landau Equation

, 1998
Of the various interesting solutions found in the two-dimensional complex Ginzburg-Landau equation for anisotropic systems, the phase-chaotic states show particularly novel features. They exist in a broader parameter range than in the isotropic case, and

Effect of high-dose rosuvastatin loading before percutaneous coronary intervention in Chinese patients with acute coronary syndrome: A systematic review and meta-analysis.

PLoS ONE, 2017
BackgroundAcute coronary syndrome (ACS) is an important disease threatening human life and health. Many studies have shown that the loading dose of atorvastatin can significantly improve the prognosis of patients with ACS, and reduce the mortality ...

An individual treatment effect approach to predict response to mineralocorticoid receptor antagonists in patients with heart failure and reduced ejection fraction

European Journal of Heart Failure, EarlyView.
Aims Mineralocorticoid receptor antagonists (MRAs) are often underused in patients with heart failure (HF) and reduced ejection fraction (HFrEF). Individual treatment effect (ITE) may assist physicians in making timely decisions about which patients are the best suited for personalized therapy.
