CONGENITAL HEART DISEASE Various reasons for repeat dilatation of stented pulmonary arteries in paediatric patients
Objective: To evaluate the reasons for repeat intervention in patients treated with balloon expandable stents for pulmonary artery stenoses, with particular analysis of the time intervals between interventions. Design: A retrospective observational study. Setting: A single paediatric cardiology centre. Patients: 38 patients, mean age 6.9 years, range 6 days to 34 years (one adult patient); mean...

متن کاملSPOTLIGHT REVIEW Biological responses in stented arteries
Vascular walls change their dimension and mechanical properties in response to injury such as balloon angioplasty and endovascular stent implantation. Placement of bare metal stents induces neointimal proliferation/restenosis which progresses through different phases of repair with time involving a cascade of cellular reactions. These phases just like wound healing comprise distinct steps consi...
متن کاملWall viscosity of the stented arteries.
Wall Viscosity of the Stented Arteries To the Editor: In the November 2003 issue of Stroke, Vernhet and colleagues reported a clinical analysis of wall mechanics in stented extracranial carotid arteries, and they concluded that stenting of these arteries induces a compliance mismatch between the native and the stented artery. Additionally, the authors observed a significant decrease in the dist...
متن کاملCollagen Matrix Remodeling in Stented Pulmonary Arteries after Transapical Heart Valve Replacement.
The use of valved stents for minimally invasive replacement of semilunar heart valves is expected to change the extracellular matrix and mechanical function of the native artery and may thus impair long-term functionality of the implant. Here we investigate the impact of the stent on matrix remodeling of the pulmonary artery in a sheep model, focusing on matrix composition and collagen (re)orie...
