Promoting endothelialisation to reduce vascular injury following coronary angioplasty and stent implantation
… outcomes in patients undergoing angioplasty and stenting for coronary artery disease. I sought to establish a new cellular model to study the coronary endothelium in patients with acute myocardial infarction, and to utilise this model to identify novel polymer substrates that promote …

The assessment of two year clinical outcomes after stent implantation for the treatment of coronary artery disease
Submitted in fulfillment of the Master’s Degree in Clinical Technology, Durban University of Technology, Durban, South Africa, Durban, South Africa, 2012.

Optimizing registration of complex vascular geometries
… for endovascular catheter intervention, such as stent implantation. Yet, these imaging modalities are not universally embraced; and thus, optimization of stent implantation and management of the adverse outcomes remain challenging. This is partially because full adoption of complex imaging awaits …

Mechanismen des Lumengewinns und der Restenosierung nach koronarer Stentimplantation von Patienten mit Metabolischem Syndrom
… on acute and long- term results after coronary stent imlpantation, however, is unknown. This systematic examination evaluated 322 patients undergoing coronary stent implantation. Clinical and angiographic follow- up was performed in all patients. In summary, there was no association between the …

Untersuchung von Krankenhauskomplikationen nach elektiver perkutaner transluminaler Koronarangioplastie bei kombinierter Vorbehandlung mit Ticlopidin und Azetylsalizylsäure
… with an increased use of coronary artery stenting in percutaneous transluminal coronary angioplasty (PTCA) was examined. Study endpoints were procedural success, the rate of PTCA-induced complications (necessity of reintervention, myocardial infarction, death, ischemic and hemorrhagic …

Prospektive randomisierte Untersuchung der Neointimaproliferation in goldbeschichteten Koronarstents im Vergleich zu herkömmlichen Edelstahlstents mittels intravaskulären Ultraschalls
In-stent restenosis is a major limitation of percutaneous coronary interventions and occurs due to neointimal hyperplasia after stent implantation. Gold coating of stainless stell stents showed an in-vitro-reduction of neointimal formation, an effect attributed to an assumed favourable …

Etablierung und Charakterisierung eines diabetischen Tiermodells zur Stent-Restenose
… disease as well as restenosis following coronary stent implantation than non-diabetics, despite tremendous advances in the fields of diabetology and invasive cardiology. Surprisingly, no acceptable diabetic animal model of in-stent restenosis has been developed to the present day. The development …

Clinical and angiographic outcome following percutaneous coronary intervention
… balloon angioplasty in the early to mid 1990s to stent implantation which has now become standard practice. It describes contributions to the extension of clinical situations in which percutaneous intervention has been found to be efficacious as well as refinements in practice and technique. I was …

The role of altered cyclic strain patterns on proliferation and apoptosis of vascular smooth muscle cells - implications for in-stent restenosis
… Coronary Angioplasty (PTCA) followed by stent implantation is the frontline treatment in the management of coronary artery disease. To-date the main drawback of stent implantation is in-stent restenosis. Restenosis is a partial re-occlusion of the arterial wall predominantly due to …

Evaluation eines Tacrolimus-beschichteten Stents zur Prävention der Restenosierung im diabetischen Tiermodell
… improved technical methods, restenosis following stent implantation remains a central problem in interventional cardiology, especially in diabetic patients. Eminent for the development of restenosis are the proliferation of smooth muscle cells, the production of extracelluar matrix and …

Klinische und angiographische Akut- und Langzeitergebnisse nach direkter Stentimplantation bei Patienten mit symptomatischer koronarer Herzkrankheit
… with coronary artery disease who undergo direct stent implantation. The values are resulted on one side from digital quantitative coronary coronarangiography (QCA) and on the other side from the clinical symptoms classified by the Canadian Cardiovascular Society (CCS) and the New York Heart …

Eine Stentimplantation außerhalb der FDA-Indikationen für DES ist unabhängig von der Wahl des Stenttyps mit einer erhöhten Stentthromboserate verbunden
For decades, implantation of stents in coronary lesions after baloon dilatation has been the gold standard therapy in stenotic coronary artery disease. With the use of bare-metal stents, the cardiologist often saw an instent restenosis, which led to the invention of drug-eluting-stents. …

Clinical outcome and Predictive factors of Coronary aneurysm after Percutaneous Coronary Intervention
… the adjacent reference vessel) at the site of stent implantation are rare and the reported incidence varies from 0.3% to 6%(Aoki et al., 2008). A new term, peri-stent contrast staining (PSS) was defined as contrast staining outside the stent contour extending to ≥20% of the stent diameter which …

Mechanismen der Restenosierung nach koronarer Stentimplantation : ein Paargruppenvergleich zwischen Diabetikern und Nicht-Diabetikern
… mellitus is an established risk factor for stent restenosis, in part as a result of smaller vessel dimensions and longer lesions. Aim of this study was to compare the magnitude of acute lumen gain and late lumen loss after elective coronary stent implantation in diabetic and non-diabetic …

Mobilisation zirkulierender endothelialer Progenitorzellen bei Patienten mit akutem Myokardinfarkt
… All patients underwent a successful PCA and a stent implantation. Both groups were matched according to age, sex and statin treatment as determinants of physiological EPC mobilization. Results showed that a STEMI lead to a homogeneous mobilization of mononuclear cells and EPCs and that acute …

Der Stellenwert der Hemobahn-Viabahn-Endoprothese in der Therapie chronisch- komplexer Läsionen der Arteria femoralis superficialis
… betrug 55 Monate. Der technische Erfolg der Stent-Implantation lag bei 98,3%. Die primären versus sekundären Offenheitsraten in den ersten 30 Tagen nach HVE-Applikation waren 90% vs. 95%. 59 primären Interventionen stehen 91 Gesamtinterventionen gegenüber. Die primären/sekundären …

Korrelation von genetischen Polymorphismen mit dem Schweregrad der Intimahyperplasie nach Stentimplantation
The instent-restenosis after coronary implantation is today the predominant problem in the cardiology. Many variables have been put in connection with instent-retenosis. After a pilot study on 100 patients this job investigated the influence of the PAI-1 promoter polymorphism on the "late loss" (a …

Computational analysis on stent geometries in carotid artery
Stent implantation is an altemative invasive technique for treating the narrowed artery or stenosis in carotid artery to restore blood to the brain. However, the restenosis process is usually observed after a few weeks of carotid stenting due to abnormal progression of atherosclerosis and …

Bleeding Risk Following Percutaneous Intervention in Patients with Diabetes Prescribed Dual Anti Platelet Therapy
… with diabetes (DM) experience higher rates of in-stent restenosis and therefore greater benefit from drug eluting stent (DES) implant at the time of percutaneous coronary intervention (PCI). DES stent implantation necessitates prolonged dual anti-platelet therapy (DAPT). While DAPT reduces the …
