Clinical outcomes of aortic root replacement after previous aortic root replacement [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2013 The study objective was to examine the short- and long-term outcomes of reoperative aortic root replacement after a previous aortic root replacement.From September 1985 to February 2011, 84 consecutive patients underwent reoperative aortic root replacement. The patients' mean age was 46 ± 15 years (range, 19-80 years), and 86% were men.

Advanced Healthcare Materials, EarlyView.This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Advanced Healthcare Materials, EarlyView.This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...

Remodelling of the aortic root in severe tricuspid aortic stenosis: implications for transcatheter aortic valve implantation [PDF]
, 2018 Detailed knowledge of aortic root geometry is a prerequisite to anticipate complications of transcatheter aortic valve (TAV) implantation. We determined coronary ostial locations and aortic root dimensions in patients with aortic stenosis (AS) and ...

Geometric models of the aortic and pulmonary roots: suggestions for the Ross procedure [PDF]
, 2017 Objective: To discuss geometric factors, which may influence long-term results relating to homograft competence following the Ross procedure, we describe the 3D morphology of the pulmonary and aortic roots.
