Management of patients requiring temporary, mechanical hemodynamic support during high- risk percutaneous coronary intervention (PCI) or in cardiogenic shock is rapidly evolving. With the availability of the Impella 2.5, CP, 5.0, LD, and RP percutaneous mechanical circulatory support devices, there is a need for continued surveillance of outcomes. Three factors underline the importance of a registry for these populations. First, large randomized trials of hemodynamic support, involving cardiogenic shock, are challenging to conduct...

We present possible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate planning for multi-messenger astronomy with gravitational waves. We estimate the sensitivity of the network to transient gravitational-wave signals, and study the capability of the network to determine the sky location of the source. We report our findings for gravitational-wave transients, with particular focus on gravitational-wave signals from the inspiral of binary neutron star systems, which are the most promising targets for multi-messenger astronomy...

To establish the clinical validity and accuracy of automatic thresholding and manual trimming (ATMT) by comparing the method with the conventional contouring method for in vivo cardiac volume measurements. CMR was performed on 40 subjects (30 patients and 10 controls) using steady-state free precession cine sequences with slices oriented in the short-axis and acquired contiguously from base to apex. Left ventricular (LV) volumes, end-diastolic volume, end-systolic volume, and stroke volume (SV) were obtained with ATMT and with the conventional contouring method...

Currently, there are no data on the use of mechanical circulatory support (MCS) in patients without severely depressed left ventricular ejection fraction (LVEF) during high-risk percutaneous coronary intervention (PCI). We analyzed data from the global catheter-based ventricular assist device (cVAD) registry on the clinical use of MCS in high-risk PCI in patients without severely depressed LVEF, defined as LVEF > 35%. Patients without cardiogenic shock from the catheter-based ventricular assist device registry, who underwent elective or urgent PCI with an Impella 2...

OBJECTIVES: To evaluate the outcomes of subadventitial stenting (SS) around occluded stents for recanalizing in-stent chronic total occlusions (IS-CTOs). BACKGROUND: There is little evidence on the outcomes of SS for IS-CTO. METHODS: We examined the outcomes of SS for IS-CTO PCI at 14 centers between July 2011 and June 2017, and compared them to historical controls recanalized using within-stent stenting (WSS). Target-vessel failure (TVF) on follow-up was the endpoint of this study, and was defined as a composite of cardiac death, target-vessel myocardial infarction, and target-vessel revascularization...

Stress testing is endorsed by the American College of Cardiology/American Heart Association Appropriate Use Criteria to identify appropriate candidates for Chronic Total Occlusion (CTO) Percutaneous Coronary Intervention (PCI). However, the relation between stress test risk classification and health status after CTO PCI is not known. We studied 449 patients in the 12-center OPEN CTO registry who underwent stress testing before successful CTO PCI, comparing outcomes of patients with low-risk (LR) versus intermediate to high-risk (IHR) findings...

De novo design provides an attractive approach to test the mechanism by which metalloproteins define the geometry and reactivity of their metal ion cofactors. While there has been considerable progress in designing proteins that bind transition metal ions including iron-sulfur clusters, the design of tetranuclear clusters with oxygen-rich environments has not been accomplished. Here, we describe the design of tetranuclear clusters, consisting of four Zn2+ and four carboxylate oxygens situated at the vertices of a distorted cube-like structure...

OBJECTIVES: Few studies have evaluated the relationship of diabetes with technical success and periprocedural complications, and no studies have compared patient-reported health status after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with and without diabetes. BACKGROUND: CTOs are more common in patients with diabetes, yet CTO PCI is less often attempted in patients with diabetes than in patients without. The association between diabetes and health status after CTO PCI is unknown...

OBJECTIVES: We sought to determine the impact of subintimal plaque modification (SPM) on early health status following unsuccessful chronic total occlusion (CTO) PCI. BACKGROUND: Intentionally dilating the subintimal space during unsuccessful CTO PCI to facilitate flow through dissection planes and improve success of repeat PCI attempts is a technique used by some hybrid operators, and may improve health status by restoring distal vessel flow despite unsuccessful CTO PCI...

Coronary perforation is a potential complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We analyzed 2,097 CTO PCIs performed in 2,049 patients from 2012 to 2017. Patient age was 65 ± 10 years, 85% were men, and 36% had prior coronary artery bypass graft surgery. Technical and procedural success were 88% and 87%, respectively. A major periprocedural adverse cardiovascular event occurred in 2.6%. Coronary perforation occurred in 85 patients (4.1%); The frequency of Ellis class 1, 2, and 3 perforations was 21%, 26%, and 52%, respectively...

OBJECTIVES: This study sought to accurately describe the success rate, risks, and patient-reported benefits of contemporary chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: In light of the evolving techniques to successfully revascularize CTO lesions, there remains a compelling need to more accurately quantify the success rates, risks, and benefits of these complex procedures. METHODS: Using a uniquely comprehensive, core-lab adjudicated, single-arm, multicenter registry of 1,000 consecutive patients undergoing CTO PCI by the hybrid approach, we evaluated the technical success rates, complication rates, and raw and adjusted health status benefits at 1 month among successfully as compared to unsuccessfully treated patients...

Single nanoparticles are shown to develop a localized acoustic resonance, the bouncing mode, when placed on a substrate. If both substrate and nanoparticle are noble metals, plasmonic coupling of the nanoparticle to its image charges in the film induces tight light confinement in the nanogap. This yields ultrastrong "acoustoplasmonic" coupling with a figure of merit 7 orders of magnitude higher than conventional acousto-optic modulators. The plasmons thus act as a local vibrational probe of the contact geometry...

This review explores the usefulness of multivessel revascularization with percutaneous coronary intervention in patients with multivessel obstructive coronary artery disease (CAD) presenting with and without cardiogenic shock. We also evaluate the literature regarding complete versus incomplete revascularization for patients with cardiogenic shock, acute coronary syndromes, and stable coronary artery disease.

INTRODUCTION: We examined the impact of proximal vessel tortuosity on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: The baseline clinical and angiographic characteristics and procedural outcomes of 1618 consecutive CTO-PCIs performed between 2012 and 2016 at 14 United States centers in 1589 patients were reviewed. RESULTS: Mean patient age was 65.3 ± 10.0 years and 85% were men. Moderate/severe proximal vessel tortuosity was present in 35...

We sought to examine the impact of calcific deposits on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The outcomes of 1,476 consecutive CTO PCIs performed in 1,453 patients (65.5 ± 10 years, 85% male) between 2012 and 2016 at 11 US centers were evaluated. Moderate or severe quantity of calcium was present in 58% of target lesions. Calcified lesions were more tortuous and more likely to have proximal cap ambiguity and interventional collaterals. PCI of moderately/severely calcified CTOs more often required use of the retrograde approach (54% vs 30%, p <0...
