AbstractObjectivesWe aimed to compare the procedural and mid-term performance of a specifically designed self-expanding stent with balloon-expandable stents in patients undergoing hybrid palliation for hypoplastic left heart syndrome and its variants.BackgroundThe lack of specifically designed stents has led to off-label use of coronary, biliary, or peripheral stents in the neonatal ductus arteriosus. Recently, a self-expanding stent, specifically designed for use in hypoplastic left heart syndrome, has become available.MethodsWe carried out a retrospective cohort comparison of 69 neonates who

Abstract:
The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy. Balloon angioplasty is a basic treatment for central

Abstract:
The management of aortoiliac insufficiency has been improved considerably since the introduction of balloon-expandable stents in 1991. Although numerous studies have shown the safety and efficacy of balloon-expandable iliac artery stent placement, the procedure is not without potential complication. We report here a very unusual case of iliac artery stenting being complicated by deformation and elongation of the stent following balloon rupture at initial deployment with retention of the distal balloon marker and our successful approach to subsequent management with combined acetylsalicylic aci

Abstract:
Purpose: To describe a method for dealing with balloon rupture during stent deployment. Technique: A 10-mL Luer-Lock syringe containing contrast material and heparinized saline is used to re-expand a balloon ruptured during stent deployment, permitting maximum balloon expansion and successful initial stent-wall apposition. No adjunctive use of probing catheters or a power injector is necessary to achieve adequate stent expansion. Analysis of the rupture may identify procedural deficiencies that can be rectified. Conclusions: This technique is simple and timesaving, and interventionists should

In-stent restenosis still remains an obsession to cardiologist, especially in tapered vessels.

The effect of stent design parameters on stent tapering and foreshortening were also researched. Results show that the radial displacement of stent proximal end was always larger than that of stent distal end during stent expansion, and the stent had a tapered shape as a whole after expansion.

In-stent restenosis (ISR) after stent implantation, especially in tapered vessels, remains an obstacle in the long-term benefits of stenting. In the present study, a finite element method (FEM) was employed to investigate the expansion process of balloon-expandable stents in tapered vessels (the TV model) and their interactions. For comparison, a numerical model of the same stent deployment in a straight vessel was also investigated.

Abstract:
Advancement of a sheath or guide catheter into a small, diseased or angled branch vessel such as the superior mesenteric artery or renal artery can be difficult. Similarly, there are times when placement of a sheath up and over a sharply angulated aortic bifurcation can present a challenge. Obtaining a sheath position at or beyond a stenotic or occlusive lesion may be critical for delivering a stent, particularly with the inherent risk of dislodgment associated with balloon-expandable stents. The use of balloons as anchors has been described most commonly in the coronary vasculature, but it ca

Abstract:
Coronary heart disease is a major health threat for people in the developed countries. Narrowing of the coronary arteries is one of the most common types of coronary heart diseases and is often treated by percutaneous transluminal coronary angioplasty (PTCA) and recently by stenting. A stenting procedure involves inserting a slotted metal tube or coil into the artery and expanding it to help achieve a sufficient luminal size. To optimize the design of stents, we have developed a finite element model of the stenting procedure. The results showed the distal ends of the stent could damage arterie

The implantation of a balloon expandable stent induces chronic stent-induced stresses on the artery wall. These highly non-physiologic stresses can provoke inflammation and smooth muscle cell proliferation.

Since the initial human implantation of balloon expandable stents, technological advances in stent design, material properties, and deliverability have expanded the application and success rate of the procedure.
