[Ability to Overcome the Thrombocyte Resistance to Acetylsalicylic Acid in Patients With Coronary Artery Disease After Myocardial Revascularization With Coronary Stenting].

Resistance to acetylsalicylic acid (ASA) in patients with coronary artery disease is a poor predictor for the development of atherothrombotic complications. In 277 patients with coronary artery disease suffered uncomplicated coronary angioplasty with stent implantation, we was estimated arachidon-induced platelet aggregation during treatment with acetylsalicylic acid by bedside VerifyNow Assay test at 28-90 days after the intervention. It was found that 18.

Isolated absence of coronary sinus: two cases report.

Coronary sinus (CS) is the venous drainage system of the heart. Absence of the coronary sinus or atresia of ostium of the CS are rarely seen cardiac malformations. Congenital absence of CS usually is found together with other cardiac malformations, however, isolated congenital absence of CS is very rare.

[The role of reduction of glomerular filtration rate in outcomes of drug-eluting stents implantation in patients with ischemic heart disease and chronic kidney disease].

Patients (n=432) subjected to percutaneous coronary interventions (PCI) with implantation of one or more drug eluting stents (DES) in 2005 were included in this study. These patients were divided into 3 groups according to baseline glomerular filtration rate (GFR): group 1 - GFR 60 ml/min/1.73 m2, n=271, group 2 - GFR 30-60 ml/min/1.

Single right coronary artery-R-I subtype: a report of an extremely rare case.

A single coronary ostium with no associated congenital cardiac disease is a rare congenital coronary-artery anomaly. However, a single right coronary artery has a much rarer incidence. We report here the antemortem diagnosis of a case with R-I subtype single coronary artery supplying the entire myocardium.

Current role of laser angioplasty of restenotic coronary stents.

Treatment of in-stent restenosis (ISR) with conventional percutaneous transluminal coronary angioplasty (PTCA) causes significant recurrent neointimal tissue growth in 30-85%. Therefore, laser ablation of intrastent neointimal hyperplasia before balloon dilation can be an attractive alternative. However, the long-term outcomes of such treatment have not been studied thoroughly enough.

Femoral pseudoaneurysm due to diagnostic or interventional angiographic procedures.

The authors investigated the incidence of, diagnostic methods for, and treatment strategies for iatrogenic femoral pseudoaneurysms in their hospital and compared the results with those in the literature. The hospital records of 25,273 patients who had coronary or peripheral angiography and angioplasty in Sani Konukoglu Medical Center from September 1997 to December 2002 were collected retrospectively. All the complications were detected and femoral pseudoaneurysm cases were selected.

Management of 28 consecutive iatrogenic femoral pseudoaneurysms with ultrasound-guided compression.

We attempted to evaluate nonsurgical methods of treating postcatheterization iatrogenic femoral pseudoaneurysms at our hospital and compared the results with those in the literature. The hospital records of 25 273 patients who underwent femoral catheterization at our institution from September 1997 to December 2002 were collected retrospectively. All complications were detected and femoral pseudoaneurysm cases were selected.

Quantitative angiographic analysis of right ventricular global function in normal incidences and in patients with coronary artery disease.

At present right ventriculography data cannot be accurately estimated owing to the absence of software for quantitative analysis of the right ventricle (RV) volumes and function. The aim of this study was to use existing software for left ventriculography analysis to estimate right ventricular volumes and function in patients without coronary lesions and in those with coronary artery disease (CAD). Thirty-two patients without significant lesions of coronary arteries and 20 patients with CAD were examined with left ventriculography and right atriography.

Complications of cardiac catheterization: a single-center study.

In Turkey as well as in the whole world, cardiac catheterization is an invasive intervention that is being increasingly used both for diagnosis and treatment. With technological and pharmacologic development and experience, the indications for this intervention are ever increasing. This invasive intervention brings, of course, some complications with it.

[Prognosis of unstable angina resulting from restenosis after percutaneous angioplasty of saphenous vein grafts].

Aim: To assess frequency of unstable angina due to restenosis after percutaneous angioplasty of venous grafts and to elucidate risk factors of its development.

Material And Methods: Percutaneous interventions were successfully performed in 100 out of 106 patients with venous graft stenoses. These patients were followed up for 17+/-11 (maximum 36) months.

[Clinical, angiographical, and procedural causes of acute vessel closure during transluminal coronary intervention].

Aim: To elucidate factors related to acute vessel closure (AVC) after transluminal coronary intervention.

Methods: From population of 10439 patients subjected to transluminal coronary intervention 2 groups were formed: with (n=885) and without (n=885) acute vessel closure (AVC). Twenty five clinical, angiographical and procedural characteristics of patients of these 2 groups were included into mono and multifactorial logistic regression analysis.

Frequency in the anomalous origin of the right coronary artery with angiography in a Turkish population.

Objective: The estimate frequency of anatomic variations in origin of the right coronary artery in a Turkish population.

Material And Method: The angiographic data of 5253 consecutive adults patients undergoing coronary angiography were analysed retrospectively for the diagnosis of anomalous origin of the right coronary artery.

Results: Among 5253 adults patients, five (0.
