Transcatheter aortic valve replacement (TAVR) is an effective, nonsurgical treatment option for patients with severe aortic stenosis. The optimal treatment strategy for treating concomitant coronary artery disease (CAD) has not been tested prospectively in a randomized clinical trial. Nevertheless, it is standard practice in the United States to perform coronary angiography and percutaneous coronary intervention for significant CAD at least 1 month before TAVR. All existing clinical trials were designed using this strategy...

Long-term clinical outcomes of new-generation drug-eluting stents in complex anatomic and clinical settings are not well defined. This study assessed the impact of patient and lesion complexity on 2-year outcomes after coronary revascularization with ultrathin strut biodegradable-polymer (BP) sirolimus-eluting stents (SES) versus durable-polymer (DP) everolimus-eluting stents (EES). In a prespecified analysis of the BIOSCIENCE randomized trial (NCT01443104), complex patients (911 of 2,119; 43%) were defined by the presence of acute ST-elevation myocardial infarction (MI); left ventricular ejection fraction ≤30%; renal dysfunction; insulin-treated diabetes; treatment of ostial lesion, bypass graft, unprotected left main lesion; or 3-vessel intervention...

BACKGROUND: Poststent fractional flow reserve (FFR) is a useful indicator of optimal percutaneous coronary intervention, and higher poststent FFR is associated with favorable long-term clinical outcome. However, little is known about the factors influencing poststent FFR. The purpose of this study was to determine the impact of lesion characteristics on poststent FFR. METHODS: For patients who had scheduled stent implantation for stable angina, FFR measurements at maximum hyperemia were performed before and after coronary stent implantation...

OBJECTIVE: With the demonstrated benefit of an early-invasive strategy for STEMI and VF/VT arrest patients, there is interest in assessing the potential benefit of early angiography for non-shockable (PEA/Asystole) arrest patients. We hypothesized that in cardiac arrest patients who obtain return of spontaneous circulation (ROSC) after a non-shockable initial rhythm and do not have STEMI the incidence of coronary intervention would be clinically insignificant (<5%). METHODS: Retrospective multicenter US clinical registry study of post-cardiac arrest patients at 18 hospitals between 1/00 and 5/14...

REVIEW
Matthew J Price
In clinical trials that assessed the safety and efficacy of cangrelor during percutaneous coronary intervention (PCI), cangrelor was administered as a 30-μg/kg bolus followed by a 4-μg/kg/min infusion for at least 2 hours or the duration of the PCI, whichever was longer. Cangrelor is currently indicated as an adjunct to PCI to reduce the risk of myocardial infarction, repeat coronary revascularization, and stent thrombosis in patients who have not been treated with a P2Y12 platelet inhibitor and are not being given a glycoprotein IIb/IIIa inhibitor...

BACKGROUND: There are some cases in whom a sufficient improvement in fractional flow reserve (FFR) could not be achieved even if anatomical results indicated satisfactory stent deployment. We investigated the relation of abnormal findings between intravascular ultrasound (IVUS) and coronary pressure pullback measurement (CP-PB). METHODS: IVUS and CP-PB were investigated after stent deployment in 60 vessels in 53 patients. CP-PB criterion for adequate stent deployment was defined as a ratio of coronary pressure at the stent distal edge to the proximal edge (Psd/Psp) that is greater than 0...

AIMS: Few data are available on outcomes of percutaneous coronary intervention (PCI) for coronary chronic total occlusions (CTO) in very elderly patients in the drug-eluting stent (DES) era. We investigated long-term survival in a single-center cohort of elderly patients following CTO PCI using DES. METHODS AND RESULTS: Consecutive 2002 patients who underwent PCI of a CTO at our center between 01/2005 and 12/2013 were followed for a median of 2.6 years (interquartile range 1...

BACKGROUND/PURPOSE: Drug-eluting stents (DES) reduce in-stent restenosis and repeat revascularization in comparison to bare metal stents. Individual DES vary, however, in regard to rates of restenosis and stent thrombosis; they also differ in regard to their platform and physical characteristics. The Promus Premier was designed to improve the performance of the Promus Element, with respect to conformability, trackability, and avoidance of longitudinal stent deformation; there is little published data, however, on clinical outcomes with Promus Premier...

Coronary artery pressure-drop and distensibility (compliance) are two major, seemingly unrelated, parameters in the cardiovascular clinical setting, which are indicative of coronary arteries patency and atherosclerosis severity. While pressure drop is related to flow, and therefore serves as a functional indicator of a stenosis severity, the arterial distensibility is indicative of the arterial stiffness, and hence the arterial wall composition. In the present study, we hypothesized that local pressure drops are dependent on the arterial distensibility, and hence can provide information on both indices...

BACKGROUND: Dual antiplatelet therapy is recommended as a standard antiplatelet strategy in acute coronary syndrome. For those with reduced pharmacologic response to clopidogrel, strengthening antiplatelet therapy (clopidogrel 150mg daily) may reduce adverse clinical events. Ticagrelor is a direct-acting inhibitor of the adenosine diphosphate receptor P2Y12 that has a more rapid onset and offset than clopidogrel. METHODS: In this retrospective study, we compared ticagrelor (180mg loading dose 90mg twice daily thereafter), clopidogrel (300mg loading dose, 75mg or 150mg daily thereafter) for the prevention of cardiovascular events in 273 high-risk patients admitted to coronary care unit with acute coronary syndrome...

BACKGROUND: In-stent neoatherosclerosis is characterized by the delayed appearance of markers of atheroma in the subintima, but the pathophysiology underlying this new disease entity remains unclear. METHODS AND RESULTS: We collected 20 human coronary artery stents by removal from explanted hearts. The mean duration of stent implantation was 34 months. In all samples, neoatherosclerosis was detected, particularly in peristrut areas. It consisted of foam cells and cholesterol clefts, with or without calcification, associated with neovascularization...

BACKGROUND: Percutaneous coronary intervention (PCI) with bare-metal and first-generation drug-eluting stents (DES) for cardiac allograft vasculopathy (CAV) is associated with unexpectedly high restenosis rates and target lesion revascularization (TLR). Long-term outcomes of stenting for CAV using second-generation everolimus-eluting stents (EES) are not established. OBJECTIVE: To evaluate clinical and angiographic outcomes of CAV stenting with EES. METHODS: Patients who underwent PCI with EES for CAV were studied...

Coronary CT angiography (CCTA) suffers from a reduced diagnostic accuracy in patients with heavily calcified coronary arteries or prior myocardial revascularisation due to artefacts caused by calcifications and stent material. CT myocardial perfusion imaging (CTMPI) yields high potential for the detection of myocardial ischemia and might help to overcome the above mentioned limitations. We analysed CT single-phase perfusion using high-pitch helical image acquisition technique in patients with prior myocardial revascularisation...

Bioresorbable vascular scaffolds (BVS) have become an attractive option in the field of percutaneous coronary intervention due to the complete resorption process that occurs over a few years. On the other hand, current generation devices have several limitations when compared to metallic drug-eluting stents including bulky struts and relatively less radial strength, and it has been indicated that an optimized implantation strategy is required. In this article, various tips and tricks to optimize implantation of current generation BVS are discussed...

Background Patients with obstructive left main coronary artery disease are usually treated with coronary-artery bypass grafting (CABG). Randomized trials have suggested that drug-eluting stents may be an acceptable alternative to CABG in selected patients with left main coronary disease. Methods We randomly assigned 1905 eligible patients with left main coronary artery disease of low or intermediate anatomical complexity to undergo either percutaneous coronary intervention (PCI) with fluoropolymer-based cobalt-chromium everolimus-eluting stents (PCI group, 948 patients) or CABG (CABG group, 957 patients)...

BACKGROUND: Patients with coronary artery disease who undergo stent implantation and have concomitant indication for long-term oral anticoagulation represent a considerable proportion of the overall population. To date there is still no consensus about the optimal antithrombotic strategy to choose in this kind of patients, due to the difficult balance between an increased risk of bleeding and thromboembolic complications. Therefore, the aim of this study was to perform a meta-analysis to evaluate the risk and benefits of triple antithrombotic therapy versus dual antithrombotic therapy in patients undergoing coronary stent implantation, requiring long-term oral anticoagulation...

: Atherosclerotic renal artery stenosis is an increasingly recognized medical problem especially in elderly patients. It commonly occurs with systemic manifestations including hypertension (HTN), chronic kidney disease (CKD) or atherosclerotic diseases including coronary or peripheral artery disease. Significant renal artery stenosis may result in HTN, ischemic nephropathy, however it is still in debate about the benefit of revascularization. Although several randomized controlled trials including Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) and Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) study has failed to reveal a significant benefit of angioplasty, angioplasty with medical therapy is increasingly accepted in some patients with certain clinical conditions...
