Myxoma of the aortic valve [PDF]

open access: yesInteractive CardioVascular and Thoracic Surgery, 2012
Myxomatous tumours can arise from different cardiac structures. They have a special predilection for the left atrium and are an exceedingly uncommon finding in cardiac valves. We report the case of a 28-year old man who presented with a stroke and was found to have a mass arising from his aortic valve.

Mechanical or Biologic Prostheses for Aortic‐Valve and Mitral‐Valve Replacement

open access: yesNew England Journal of Medicine, 2017
BACKGROUND In patients undergoing aortic‐valve or mitral‐valve replacement, either a mechanical or biologic prosthesis is used. Biologic prostheses have been increasingly favored despite limited evidence supporting this practice. METHODS We compared long‐

Wall shear stress and pressure patterns in aortic stenosis patients with and without aortic dilation captured by high-performance image-based computational fluid dynamics [PDF]

open access: yesarXiv, 2022
Spatial patterns of elevated wall shear stress and pressure due to blood flow past aortic stenosis (AS) are studied using GPU-accelerated patient-specific computational fluid dynamics. Three cases of moderate AS, one with a dilated ascending aorta and two within the normal range (root diameter less than 4cm) are simulated for physiological beat cycle ...

Valve-sparing aortic root replacement and remodeling with complex aortic valve reconstruction in children and young adults with moderate or severe aortic regurgitation [PDF]

open access: yes, 2014
ObjectivesThe durability of valve-sparing aortic root procedures with aortic regurgitation due to leaflet disease is questioned. Here, we review our experience in combined aortic root and valve reconstruction in children and young adults.MethodsAll valve-

Incidence, predictors, and clinical outcomes of coronary obstruction following transcatheter aortic valve replacement for degenerative bioprosthetic surgical valves: insights from the VIVID registry

open access: yesEuropean Heart Journal, 2018
Aims There are limited data on coronary obstruction following transcatheter valve-in-valve (ViV) implantation inside failed aortic bioprostheses. The objectives of this study were to determine the incidence, predictors, and clinical outcomes of coronary ...

Children With 22.Q.11.2 Deletion Syndrome: Sleep‐Disordered Breathing and Management

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Patients with 22q11.2 deletion syndrome (22q11DS) are predisposed to obstructive sleep apnea (OSA) due to an abnormal craniofacial anatomy with pharyngeal hypotonia, retrognathia, micrognathia, and glossoptosis. The aim of the study was to describe the prevalence and management of OSA in a cohort of children with 22q11DS.

Aortic Valve Sparing in Different Aortic Valve and Aortic Root Conditions

open access: yesJournal of the American College of Cardiology, 2016
The development of aortic valve-sparing operations (reimplantation of the aortic valve and remodeling of the aortic root) expanded the surgical armamentarium for treating patients with aortic root dilation caused by a variety of disorders. Young adults with aortic root aneurysms associated with genetic syndromes are ideal candidates for reimplantation ...

Histopathology reveals concealed aortic valve inflammation

open access: yesJournal of Cardiothoracic Surgery
Background The extent of aortic valve inflammation in patients undergoing aortic valve replacement (AVR) is unsettled. The significance of aortic valve histopathology in patients undergoing AVR is undetermined.

The bicuspid aortic valve - studies on valve morphology and pathology in relation to ascending aortic dilatation and coronary artery disease [PDF]

open access: yes, 2013
The prevalence of bicuspid aortic valve (BAV) is 1 - 2% and is thereby the most common cardiac malformation. BAV is highly associated with valvular dysfunction and aortic co nditions such as ascending aortic aneurysm and aortic ...
