The effect of varying degrees of stenosis on transition to turbulence in oscillatory flows [PDF]

arXiv, 2022
Many complications in physiology are associated with a deviation in flow in arteries due to a stenosis. The presence of stenosis may transition the flow to weak turbulence. The degree of stenosis as well as its configuration whether symmetric or non-symmetric to the parent artery influences whether the flow would stay laminar or transition to ...

Coronary Artery Semantic Labeling using Edge Attention Graph Matching Network [PDF]

, 2023
Coronary artery disease (CAD) is one of the primary causes leading deaths worldwide. The presence of atherosclerotic lesions in coronary arteries is the underlying pathophysiological basis of CAD, and accurate extraction of individual arterial branches using invasive coronary angiography (ICA) is crucial for stenosis detection and CAD diagnosis.

Remote Ischemic Preconditioning Neither Improves Survival nor Reduces Myocardial or Kidney Injury in Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI) [PDF]

, 2020
BACKGROUND: Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month ...

StenUNet: Automatic Stenosis Detection from X-ray Coronary Angiography [PDF]

arXiv, 2023
Coronary angiography continues to serve as the primary method for diagnosing coronary artery disease (CAD), which is the leading global cause of mortality. The severity of CAD is quantified by the location, degree of narrowing (stenosis), and number of arteries involved.

Preoperative and perioperative use of levosimendan in cardiac surgery: European expert opinion [PDF]

, 2015
In cardiac surgery, postoperative low cardiac output has been shown to correlate with increased rates of organ failure and mortality. Catecholamines have been the standard therapy for many years, although they carry substantial risk for adverse cardiac ...

Inhibition of in-stent stenosis by oral administration of bindarit in porcine coronary arteries [PDF]

, 2011
<p><b>Objective:</b> We have previously demonstrated that bindarit, a selective inhibitor of monocyte chemotactic proteins (MCPs), is effective in reducing neointimal formation in rodent models of vascular injury by reducing smooth ...

When stenting in renal artery stenosis? Update on pathophysiology of ischemic nephropathy and management strategies

Italian Journal of Medicine, 2013
In recent years, decisions taken on the optimal management of patients with renal artery stenosis have triggered off controversy and debate among clinicians dealing with renovascular disease. The main reason underlying this ongoing controversy may be the

Biohybrid Vascular Graft Made of Textile‐Reinforced Elastin‐Like Recombinamers and Its Preservation via Drying Processes

Advanced Healthcare Materials, EarlyView.
Clinical translation of biohybrid medical implants requires the previous implementation of drying schemes that can facilitate their sterilization and storage. This study addresses that critical aspect and elucidates the impact of drying on biohybrid vascular grafts, highlighting the need for implant‐specific drying strategies to ensure safety ...
