Evaluation of the Transcatheter Aortic Valve Replacement Results in Patients with Borderline Aortic Annulus and the Impact of Under- or Oversizing the Valve

open access: yesAnatolian Journal of Cardiology, 2023
Background: Optimal valve sizing provides improved results in transcatheter aortic valve replacement. Operators hesitate about the valve size when the annulus measurements fall into borderline area.

Selective, segmental decalcification: a safe alternative to extensive debridement of a severely calcified annulus during repair of mitral regurgitation. [PDF]

open access: yes, 2016
Resection of the calcium bar and creation of a more compressible annulus with pericardium are necessary in case of extensive calcification of the mitral valve annulus in patients with advanced myxomatous degenerative disease.

Numerical Solution of Natural Convection Problems Using Radial Point Interpolation Meshless (RPIM) Method Combined with Artificial-Compressibility Model

open access: yesMathematical and Computational Applications
A numerical method is used to solve the thermal analysis of natural convection in enclosures. This paper proposes the use of an implicit artificial-compressibility model in conjunction with the Radial Point Interpolation Meshless (RPIM) method to mimic ...

Unsteady flow of fractional Oldroyd-B fluids through rotating annulus

open access: yesOpen Physics, 2018
In this paper exact solutions corresponding to the rotational flow of a fractional Oldroyd-B fluid, in an annulus, are determined by applying integral transforms. The fluid starts moving after t = 0+ when pipes start rotating about their axis.

Mitral annulus calcification

open access: yesInternational Journal of Clinical Practice, 1990
SummaryA 67‐year‐old woman had aortic and mitral annulus calcification resulting in severe stenosis and incompetence of the valves. Mitral annulus calcification produces specific echocardiographic abnormalities which may forewarn of technical difficulties during surgery.

Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Injectivity of the Dirichlet-to-Neumann Functional and the Schwarzian Derivative

open access: yesAnais da Academia Brasileira de Ciências, 2010
In this article, we show the relation between the Schwartz kernels of the Dirichlet-to-Neumann operators associated to the metrics g0 and h = F* (e²φ g0) on the circular annulus A R, and the Schwarzian Derivative of the argument function f of the ...
