Effect of hypertension on low-density lipoprotein transport within a multi-layered arterial wall: modelling consistent with experiments [PDF]

arXiv, 2016
The influence of hypertension on low-density lipoproteins intake into the arterial wall is an important factor for understanding mechanisms of atherosclerosis. It has been experimentally observed that the increased pressure leads to the higher level of the LDL inside the wall.

Automated segmentation of the pulmonary arteries in low-dose CT by vessel tracking [PDF]

arXiv, 2011
We present a fully automated method for top-down segmentation of the pulmonary arterial tree in low-dose thoracic CT images. The main basal pulmonary arteries are identified near the lung hilum by searching for candidate vessels adjacent to known airways, identified by our previously reported airway segmentation method.

Coronary Plaque Characteristics Assessed by Optical Coherence Tomography and Plasma Lipoprotein(a) Levels in Patients With Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood. Aims This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high‐risk subset of patients ...

Management of Cardiac Implantable Electronic Devices in Patients With Severe Symptomatic Tricuspid Regurgitation—Proposed Algorithm and Selected Case Examples

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe tricuspid regurgitation (TR) is associated with significant morbidity and mortality. Management of severe TR includes treatment of the underlying cause(s), medical therapy and less commonly surgical tricuspid valve repair. Newer transcatheter tricuspid valve repair devices show promise for those patients who remain symptomatic with ...

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Markov Chain Monte Carlo with Gaussian Process Emulation for a 1D Hemodynamics Model of CTEPH [PDF]

arXiv
Microvascular disease is a contributor to persistent pulmonary hypertension in those with chronic thromboembolic pulmonary hypertension (CTEPH). The heterogenous nature of the micro and macrovascular defects motivates the use of personalized computational models, which can predict flow dynamics within multiple generations of the arterial tree and into ...
