Although proof-based medicine has generated much valid evidence for the drawing up of guidelines and recommendations for best clinical practice in symptomatic and asymptomatic carotid stenosis, whether and when it is better to employ endarterectomy or stenting as the intervention of choice still remain matters of debate. Moreover, guidelines have been targeted up to now to the 'representative' patient, as resulting from the statistical analyses of the studies conducted on the safety and efficacy of both interventions as well as on medical therapy alone...

Therapeutic devices for acute myocardial infarction (AMI) have evolved dramatically in recent years. However, the impact of the Killip classification of AMI outcomes in patients undergoing aggressive percutaneous coronary intervention remains unclear. We performed a 10-year retrospective review of 2062 patients diagnosed with AMI, and divided the data into two 5-year intervals: 2005-2009 (n = 1071), and 2010-2014 (n = 991). No difference was observed in in-hospital mortality rate between the two periods (first period, 11...

BACKGROUND: To eliminate some of the potential late limitations of permanent metallic stents, the bioresorbable coronary stents or 'bioresorbable vascular scaffolds' (BVS) have been developed. METHODS: We reviewed all currently available clinical data on BVS implantation. RESULTS: Since the 2015 position statement on the appropriateness of BVS in percutaneous coronary interventions, several large randomised trials have been presented. These have demonstrated that achieving adequate 1 and 2 year outcomes with these first-generation BVS is not straightforward...

For nearly half a century, coronary artery bypass grafting has been the standard treatment for patients with obstructive left main coronary artery (LMCA) disease. However, there has been considerable evolution in the field of percutaneous coronary intervention, and especially, percutaneous coronary intervention for LMCA disease has been rapidly expanded with adoption of drug-eluting stents. Some, but not all randomized trials, have shown that percutaneous coronary intervention with drug-eluting stents might be a suitable alternative for selected patients with LMCA disease instead of bypass surgery...

BACKGROUND: One of the disadvantages of carotid artery stenting (CAS) is high incidence of distal embolism (DE) during or after the procedure. It has been reported that unstable plaque cases are at high risk of DE and plaque protrusion (PP) after stent placement which will become a cause of post procedural ischemic complications. OBJECTIVE: The purpose of this study was to compare the rate and size of PP between CASPER stent which is a new generation double-layer micromesh stent and conventional stents detected by optical frequency domain imaging (OFDI) and to evaluate the efficacy of CAS with CASPER stent for cases with unstable plaque...
