INTRODUCTION: Risk stratification is nowadays crucial when estimating the patient's prognosis in terms of treatment outcome and it also helps in clinical decision making. Several risk assessment models have been developed to predict short-term outcomes in patients with acute coronary syndrome. This study was aimed at developing an outcome prediction model for patients with acute coronary syndrome submitted to percutaneus coronary intervention using data mining approach. MATERIAL AND METHODS: A total of 2030 patients hospitalized for acute coronary syndrome and treated with percutaneous coronary intervention from December 2008 to December 2011 were assigned to a derivation cohort...

Despite advances in percutaneous coronary interventions and the introduction of drug eluding stents, in-stent restenosis and stent thrombosis remain a clinically significant problem for bifurcations. The aim of this study is to determine the effect of dual bifurcation stenting on hemodynamic parameters known to influence restenosis and thrombosis. We hypothesized that double stenting, especially with a longer side branch (SB) stent, likely has a negative effect on wall shear stress (WSS), WSS gradient (WSSG), and oscillatory shear index (OSI)...

OBJECTIVES: The incidence of patients with refractory angina (RA) is increasing. Medical therapy for RA is limited and prognosis is poor. Experimental data suggest that the use of Extracorporeal shockwave myocardial revascularization (ESMR) may contribute to angiogenesis and improve symptoms of angina in patients with RA. Purpose of our study is to determine the efficacy of cardiac shock wave therapy (ESMR) in the management of patients with nonrevascolarized coronary artery disease (CAD)...

Antiplatelet therapy plays an important role in the treatment of patients suffering from acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) in order to prevent atherothrombotic events and restenosis or ischemic reocclusion, respectively. Moreover, stent implantation is often performed along with PCI to ensure that the arteries remain open. However, stent thrombosis ST is a possible complication which can occur up to about one year after the procedure. Therefore, it is standard to treat patients with a dual antiplatelet regime whereby aspirin is combined with either clopidogrel, prasugrel or ticagrelor...

Perforation of coronary arteries is a relatively rare yet life-threatening complication of percutaneus coronary interventions and is encountered in approximately 0.5% of these procedures. According to the type of coronary perforation, various methods of correction are employed, ranging from conservative approach to emergency cardiac surgery. Coronary stent-grafts are composed of two metal stents and a polytetrafluoroethylene layer between them. Advent of such stents enabled efficient endovascular repair of coronary artery perforation...

According to current guidelines surgical revascularisation is a gold standard of treatment in patients with multivessel and left main coronary disease. Hybrid revascularisation, in two stages: first - minimally invasive direct coronary artery bypass grafting procedure with left internal mammary artery conduit to left anterior descending artery and second stage - percutaneus coronary intervention with drug eluting stent in non-left anterior descending vessels may be safe and effective alternative in patients with multivessel and left main coronary disease...

Acute myocardial infarction (AMI) due to the occlusion of the left main coronary artery (LMCA) is a rare but serious condition in the era of percutaneus coronary intervention (PCI). Even more rare is AMI involved with both LMCA and its branches like trifurcartion or bifurcation: this is challenging for interventional cardiologists, because it involves the extension of the myocardium complicated by cardiogenic shock and its technical difficulties. Trifurcating coronary artery disease is a complex atherosclerotic process involving the origin of one or more of three side branches arising from a left main coronary vessel or trunk, with or without the involvement of LMCA itself...

ST-elevation myocardial infarction (STEMI), caused by acute occlusion of the infarct-related coronary artery, is an emergency condition. The primary therapy is restoration of full antegrade flow by either percutaneus coronary intervention (PCI) or thrombolytic therapy (TT). Although primary PCI is superior to TT in patients with STEMI, there are many limitations in clinical practice. TT decreases mortality in STEMI patients, but as experience with thrombolytic agents grows, the potential risks of serious side effects become more apparent...

OBJECTIVES: Cardiogenic shock (CS) still remains one of the most important factors affecting the mortality rate of patients with ST segment elevation myocardial infarction (STEMI). However, the data with follow-up longer than 1 year are limited. The aim of this study was to evaluate the early and long-term treatment results of patients with STEMI, complicated or not by CS, who underwent percutaneus coronary interventions. METHODS: A retrospective registry included data of all patients with STEMI admitted to our centre from January 1999 to December 2001...

In industrial countries, cardiovascular diseases remain the primary cause of death. This review summarizes the role of percutaneous coronary interventions (PCI) in the treatment of coronary heart disease. Interventional therapy of coronary artery disease was initiated in 1977 with the introduction of balloon angioplasty by Andreas Grüntzig in Zurich. Technical progress since has been related to construction and materials of catheters, but also to digital processing of x-ray imaging. Additional methods - rotablation, atherectomy, laser, intravascular ultrasound, and most importantly stent implantation were developed...

A 65-year-old man was admitted to the hospital because of effort chest pain, 8 years after he received coronary artery bypass grafting [CABG: left internal thoracic artery (LITA) to left anterior descending artery (LAD), saphenous vein graft (SVG) to first diagonal branch (D1) and SVG to postero-lateral branch (PL)]. Emergent coronary angiography revealed right coronary artery occlusion with well patent bypass grafts. Percutaneus coronary intervention (PCI) was performed successfully, but 9 hours later, ventricular septal perforation (VSP) was occurred...

Current guidelines recommend dual antiplatelet therapy using aspirin and clopidogrel for non-ST elevation acute coronary syndromes (ACS). Despite the established benefits of this approach, many patients continue to have recurrent atherothrombotic events. Moreover, it is often difficult to achieve an adequate inhibition of platelet aggregation with clopidogrel in clinical practice. Prasugrel is an orally administered P2Y12 receptor antagonist that is more potent, more rapid in onset and more consistent in its inhibition of platelet aggregation than currently approved doses of clopidogrel...

After the approval of the drug-eluting coronary stent in Japan in 2004, Japanese cardiologists took the benefit of this new technology to improve the post percutaneus coronary intervention complication of restenosis. Post market studies of drug-eluting coronary stent are becoming available. Unfortunately, many of the results indicate the risk of late stent thrombosis. The chance of stent thrombosis seems elevated when a patient is without antiplatelet medication, dehydrated and in a stressed state. Operation puts the patient in such adverse conditions that might render him to thrombo-producting state...

BACKGROUND: Knowledge of the anatomy of the coronary venous system (CVS) is important for planning of cardiac interventions like cardiac resynchronization therapy or percutaneus mitral annuloplasty. Different methods have been used for preprocedural visualization of the CVS. However, limited data is available comparing invasive retrograde coronary sinus angiography (CSA) and non-invasive multi slice computed tomography (MSCT). Thus, a comparison of retrograde CSA and ECG-gated MSCT for the visualization of the CVS in patients with congestive heart failure (CHF) was performed...

A 76-year-old man presented with an anterior myocardial infarction. Coronary angiography showed 99% stenosis in the left anterior descending artery and total occlusion in the left circumflex artery (LCX). After successful percutaneus coronary intervention (PCI) for segment 7, a staged PCI to the LCX with a distal protection system was attempted, but the wire entered the subintima, creating a large dissection and intramural hematoma. Three sirolimus-eluting stents (SES) were implanted to cover the entire hematoma, but 2 weeks later intravascular ultrasound revealed stent malapposition, with healing of the residual hematoma, and vessel enlargement...

Medical doctors, who practice interventional cardiology, receive a noticeable radiation dose. In this study, we measured the radiation dose to 9 cardiologists during 144 procedures (72 coronary angiographies and 70 percutaneus translumined coronary angioplasties) in two Greek hospitals. Absorbed doses were measured with TLD placed underneath and over the lead apron at the thyroid protective collar. Based on these measurements, the effective dose was calculated using the Niklason method. In addition, dose area product (DAP) was registered...
