Flow-volume curve analysis for predicting recurrence after endoscopic dilation of airway stenosis [PDF]

open access: yes, 2019
The flow-volume curve is a simple test for diagnosing upper airway obstruction. We evaluated its use to predict recurrence in patients undergoing endoscopic dilation for treatment of benign upper airway ...

Automated Detection of Coronary Artery Stenosis in X-ray Angiography using Deep Neural Networks [PDF]

open access: yesarXiv, 2021
Coronary artery disease leading up to stenosis, the partial or total blocking of coronary arteries, is a severe condition that affects millions of patients each year. Automated identification and classification of stenosis severity from minimally invasive procedures would be of great clinical value, but existing methods do not match the accuracy of ...

Presence Of A Congenitally Bicuspid Aortic Valve Among Patients Having Combined Mitral And Aortic Valve Replacement [PDF]

open access: yes, 2012
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent.

Flow and Deformation in a Multi-Component Arterial Stenosis Model

open access: yesJournal of Biomechanical Science and Engineering, 2011
Arterial stenoses consisting of atherosclerotic plaque are subject to mechanical forces under pulsatile blood flow that may cause plaque rupture, which often leads to heart attack or stroke.

Coronary atherosclerosis scoring with semiquantitative CCTA risk scores for prediction of major adverse cardiac events: Propensity score-based analysis of diabetic and non-diabetic patients. [PDF]

open access: yes, 2020
AIMS:We aimed to compare semiquantitative coronary computed tomography angiography (CCTA) risk scores - which score presence, extent, composition, stenosis and/or location of coronary artery disease (CAD) - and their prognostic value between patients ...

Simulation of hemodynamics in artery with aneurysm and stenosis with different geometric configuration

open access: yesJournal of Biomechanical Science and Engineering, 2014
In previous published research, the deployment of flow-diversion increases the intra-aneurysmal pressure by 20 mmHg in the case with a pre-aneurysm stenosis. The purpose of this study is to learn the influence to the aneurysm when a pre-aneurysm stenosis

Diagnostic Performance of Angiography-Based Fractional Flow Reserve for Functional Evaluation of Coronary Artery Stenosis

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: A new method for calculating fraction flow reserve (FFR) without pressure-wire (angiography-derived FFR) based on invasive coronary angiography (ICA) images can be used to evaluate the functional problems of coronary stenosis.Objective: The ...
