Despite available pharmacological and interventional therapies, refractory angina is a common and disabling clinical condition, and a major public health problem, which affects patients' quality-of-life, and has a significant impact upon health care resources. Persistent angina is common not only in patients who are not good candidates for revascularization, but also in patients following successful revascularization. Clearly, there is a need for additional treatment options for refractory angina beyond currently available pharmacological and interventional therapies...

Neoatherosclerosis is a form of accelerated atherosclerosis that occurs within stented segments of the coronary vessel late or very late after drug-eluting stent (DES) implantation via percutaneous coronary intervention (PCI). This proliferation of neointima with a formation of new atheromatous plaque within stent struts lacking re-endothelialization can provoke thrombotic occlusion and lead to catastrophic acute coronary events. Knowing that coronary artery disease is the leading single cause of mortality worldwide and that there is a constant trend of increase in PCI procedures, it is reasonable to conclude that late thrombotic events and neoatherosclerosis post-PCI remain an important therapeutic challenge...

Well into the 21st century, we still triage acute myocardial infarction on the basis of the presence or absence of ST-segment elevation, a century-old technology. Meanwhile, we have learned a great deal about the pathophysiology and mechanisms of acute coronary syndromes (ACS) at the clinical, pathological, cellular, and molecular levels. Contemporary imaging studies have shed new light on the mechanisms of ACS. This review discusses these advances and their implications for clinical management of the ACS for the future...

BACKGROUND: Movement of the stent delivery system in the coronary bed as a result of the cardiac cycle is a well-known clinical observation that usually is either underestimated or ignored. This effect may potentially jeopardize precise stent deployment. We used a novel technology to objectively measure the relative intracoronary device motion in the different coronary segments throughout the cardiac cycle. METHODS: A total of 193 patients undergoing coronary angiography were enrolled and their studies were analyzed for device movement using the SyncVision System (Philips Volcano)...

Drug-eluting stents (DES) have reached a high safety and efficacy profile, becoming the best option for percutaneous coronary interventions (PCI) based revascularization. However, despite their optimal performance, a few concerns remain regarding their use, mainly due to permanent caging of the vessels and its consequences, first of all late stent thrombosis (ST). Bioresorbable scaffolds (BRS) aim to overcome these issues. The results achieved in randomized controlled trials (RCT) by the first generation of poly-L-lactic acid (PLLA) based scaffolds were promising at 1 year, but the first long term reports (albeit flawed by non-optimal implantation technique) have been disappointing, showing, for instance, an increased risk of ST and target vessel myocardial infarction (TV-MI)...

New-generation drug-eluting stents (DES) represent the current standard of care in patients undergoing percutaneous coronary intervention (PCI). Biodegradable polymer DES (BP-DES) were recently developed to overcome current limitations of newer-generation durable polymer DES (DP-DES) attributed to sustained inflammatory responses induced by permanent polymers. The Orsiro DES (Biotronik AG, Bülach, Switzerland) is a novel thin-strut cobalt-chromium sirolimus-eluting stent with biodegradable polymer that features some of the latest developments in DES technology...

BACKGROUND: The development of coronary drug-eluting stents has included use of new metal alloys, changes in stent architecture, and use of bioresorbable polymers. Whether these advancements improve clinical safety and efficacy has not been shown in previous randomised trials. We aimed to examine the clinical outcomes of a bioresorbable polymer sirolimus-eluting stent compared with a durable polymer everolimus-eluting stent in a broad patient population undergoing percutaneous coronary intervention...

Four decades after its introduction into clinical practice, coronary balloon angioplasty is still used during most coronary interventions. Conventional balloon angioplasty is frequently used to predilate complex or severe lesions and remains of major value to optimise the results of stent implantation. Plain balloon angioplasty is still used alone in some anatomic scenarios where stent implantation is not desirable (very small vessels or diffuse lesions, large resistant thrombus burden, side branches of bifurcations)...

It has been 40 years since percutaneous coronary intervention (PCI) was introduced into the clinical setting. Over these years significant advances in device technology and the invention of new therapeutic strategies have broadened its applications in the clinical arena, rendering this treatment the first-line therapy for patients with obstructive coronary artery disease. The evolution of PCI would not have been possible without intravascular imaging which provided unique insights about coronary artery pathology, enabled evaluation of vessel wall response following PCI and allowed meticulous evaluation of the advantages and limitations of emerging devices...

In the early days of coronary angiography, the precise quantification of luminal narrowing was challenging. The introduction of balloon angioplasty (percutaneous transluminal coronary angioplasty [PTCA]) by Andreas Grüntzig in 1977 was perhaps the greatest incentive to the development of quantitative coronary angiography (QCA). QCA has played a crucial role in evaluating interventional techniques and assessing the results of new technologies. With the advent of drug-eluting stents (DES), QCA metrics such as late lumen loss and diameter stenosis (restenosis) proved to be instrumental in assessing new technologies...

Percutaneous coronary intervention in patients with cardiac allograft vasculopathy is burdened with a lot of difficulties. Although they have allowed significant progress in comparison with plain balloon angioplasty and bare metal stents, drug-eluting stents have not fully overcome problems of diffuse lesions and small-vessel disease that are so common in transplant coronary artery disease. There is growing evidence that drug-eluting balloons might be a better choice for patients with small vessel atherosclerotic coronary disease and yet there is no experience with this technology in patients with cardiac allograft vasculopathy...

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...

Optical coherence tomography (OCT) is an intra-coronary diagnostic technique that provides detailed imagings of blood vessels in the current cardiac catheterization laboratory. The higher resolution of OCT often provides superior delineation of each structure compared with intravascular ultrasound (IVUS), and it can reliably visualize the microstructure of normal and diseased arteries. The capabilities of OCT are well suited for the identification of calcified plaque and neointima formation after stent implantation...

The OPTIS integrated system (St. Jude Medical) is a new technology allowing the online co-registration of optical coherence tomography (OCT) images with the angiogram in the catheterization laboratory. Additionally, 3D navigation can be performed. This integration of OCT information on an angiographic roadmap could find broad application in the characterization of substrates causing acute coronary syndromes with normal or near-normal coronary arteries. The utility of OCT with co-registration for the guidance of percutaneous coronary intervention could be considerable in the management of patients with acute coronary syndromes...

BACKGROUND: Amphilimus sirolimus-eluting stents (A-SES) represent a novel elution technology in the current era of drug-eluting stents with promising results in patients with diabetes mellitus. At present no large trial has been designed to evaluate clinical outcomes of A-SES as compared to new-generation drug-eluting stents in unselected patients. Accordingly, we designed this trial to evaluate clinical noninferiority of A-SES as compared with zotarolimus-eluting stents (ZES) in a real-world, all-comers setting...

Intravascular ultrasound (IVUS) imaging provides two-dimensional (2D) real-time luminal and transmural cross-sectional images of intravascular vessels with detailed pathological information. It has offered significant advantages in terms of diagnosis and guidance and has been increasingly introduced from coronary interventions into more generalized endovascular surgery. However, IVUS itself does not provide spatial pose information for its generated images, making it difficult to construct a 3D intravascular visualization...

BACKGROUND: Continuous improvements in stent technology make percutaneous coronary intervention (PCI) a potential alternative to surgery in selected patients with unprotected left main coronary artery (uLMCA) disease. The optimal duration of dual antiplatelet therapy (DAPT) in these patients remains undetermined, and in addition, new stent designs using a bioabsorbable polymer might allow shorter duration of DAPT. STUDY DESIGN: IDEAL-LM is a prospective, randomized, multicenter study that will enroll 818 patients undergoing uLMCA PCI...

Physical activity is associated with a lower risk of coronary heart disease/cardiovascular disease mortality, and current guidelines recommend physical activity for primary prevention in healthy individuals and secondary prevention in patients with coronary heart disease/cardiovascular disease. Over the last decade, playing classic video games has become one of the most popular leisure activities in the world, but is associated with a sedentary lifestyle. In the new era of rapidly evolving augmented reality technology, Pokémon Go, a well-known augmented reality game, may promote physical activity and prevent cardiovascular disease risks - that is, diabetes, obesity, and hypertension...
