Bioresorbable scaffold coated with antimitotic drug is the latest development in the coronary stents technology. The concept of temporary scaffolding and natural vessel healing after angioplasty is a very attractive alternative to conventional metal stents. The results of the first observational studies have confirmed their ultimate biodegradation. Newest results of randomised trials and registries in broader clinical and anatomical indications also revealed the limitations of the first generation of scaffolds...

REVIEW
Thierry Carrel, Bernhard Winkler
The procedure of coronary artery bypass grafting continues to be the "gold standard" for patients with multivessel coronary artery disease and left main stenosis due to favourable long-term and consistent outcomes despite the advent of new generations of stents. But the targeted better long-term outcome of surgical revascularization over percutaneous interventions depends on several variables and aspects; one of them is the choice of conduits used to bypass the stenosed arteries. Coronary artery bypass surgery has been studied and debated for decades and the same applies to the selection of grafts...

Complexity of the spatial configuration of an aortic implant with bifurcation in the distal part is related to changes in blood hemodynamic in the area of bifurcation which may disturb blood flow and lead to thrombus formation. This study was designed to characterize parameters which define spatial configuration of an aortic implant for which the risk of thrombus formation is the smallest. We used AngioCT data from 74 patients, aged 55 ±10 years, after endovascular procedure to prepare 3D geometries of stent-grafts...

Bioresorbable scaffolds (BRS) were designed more than 30 years ago to overcome the disadvantages related to the permanent implantation of a metallic stent and, at present, a number of these devices have obtained a CE mark on the basis of midterm follow-up studies. However, although BRS have already been introduced into clinical practice, intensive research is ongoing worldwide to clarify their long-term safety and effectiveness. This type of research has captivated the interest of the cardiovascular community after the recent publication of long-term follow-up data from randomised trials demonstrating increased late scaffold thrombosis in the Absorb™ BRS (Abbott Vascular, Santa Clara, CA, USA)...

Lack of evidence base on the use of 2-nd generation drug covered stents in patients with ST-elevation myocardial infarction (STEMI) with multivessel lesions in coronary vascular bed makes it important to conduct studies of new devices in a framework of multivessel stenting in primary percutaneous coronary intervention (PPCI) and staged revascularization. Controversial data on outcomes of the strategy of multiple revascularization in STEMI might be related to the use of previous generation coronary stents in this category of patients...

Trifecta valve is a 3rd-generation, stented bioprosthesis which is made from one bovine pericardial sheet. A 77-years-old male patient had undergone combine aortic valve replacement (AVR) using a 23-mm Trifecta valve and ascending aorta replacement for severe aortic valve regurgitation and ascending aorta aneurysm. The postoperative period was uneventful. However, he presented with dyspnea on effort and severe aortic valve regurgitation 31 months after operation. Re-do AVR with a new bioprosthetic valve was performed via 2nd sternotomy...

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...
