BACKGROUND: The Mission: Lifeline STEMI Systems Accelerator program, implemented in 16 US metropolitan regions, resulted in more patients receiving timely reperfusion. We assessed whether implementing key care processes was associated with system performance improvement. METHODS AND RESULTS: Hospitals (n=167 with 23 498 ST-segment-elevation myocardial infarction patients) were surveyed before (March 2012) and after (July 2014) program intervention. Data were merged with patient-level clinical data over the same period...

BACKGROUND: There are only limited studies reporting clinical outcomes after bioresorbable vascular scaffold (BVS; Absorb; Abbott Vascular, Santa Clara, CA) implantation for coronary chronic total occlusions (CTO). The aim of this study was to evaluate the real-world feasibility and safety of BVS implantation for the treatment of CTO. METHODS AND RESULTS: We retrospectively evaluated CTO cases treated with BVS from a multicenter registry. The primary end point was target lesion failure defined as a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization...

BACKGROUND: The incidence of contrast-induced acute kidney injury is strongly related to the amount of the given contrast. Our objectives were to evaluate the efficacy and safety of coronary sinus aspiration (CSA) procedure to reduce the volume of the given contrast and attenuate the risk of contrast-induced acute kidney injury. METHODS AND RESULTS: The study included 43 patients with type 2 diabetes mellitus and renal impairment (creatinine 1.5-3 mg/dL) who were candidates for coronary angiography...

The experience with transcatheter aortic valve replacement is increasing worldwide; however, the incidence of potentially catastrophic cardiac or aortic complications has not decreased. In most cases, significant injuries to the aorta, aortic valve annulus, and left ventricle require open surgical repair. However, the transcatheter aortic valve replacement patient presents a unique challenge as many patients are at high or prohibitive surgical risk and, therefore, an open surgical procedure may not be feasible or appropriate...

BACKGROUND: Cangrelor is a potent intravenous adenosine diphosphate-receptor antagonist that in the CHAMPION trials reduced the 48-hour and 30-day rates of ischemic events during percutaneous coronary intervention without an increase in severe bleeding. METHODS AND RESULTS: CHAMPION PCI (A Clinical Trial to Demonstrate the Efficacy of Cangrelor), CHAMPION PLATFORM (Cangrelor Versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition), and CHAMPION PHOENIX (A Clinical Trial Comparing Cangrelor to Clopidogrel Standard Therapy in Subjects Who Require Percutaneous Coronary Intervention) were 3 randomized, double-blind, double-dummy trials in which cangrelor was compared with clopidogrel during percutaneous coronary intervention...

BACKGROUND: Readmissions after cardiac procedures are common and contribute to increased healthcare utilization and costs. Data on 30-day readmissions after transcatheter aortic valve replacement (TAVR) are limited. METHODS AND RESULTS: Patients undergoing TAVR (International Classification of Diseases-Ninth Revision-CM codes 35.05 and 35.06) between January and November 2013 who survived the index hospitalization were identified in the Nationwide Readmissions Database...

BACKGROUND: Tetralogy of Fallot with cyanosis requiring surgical repair in early infancy reflects poor anatomy and is associated with more clinical instability and longer hospitalization than those who can be electively repaired later. We bridged symptomatic infants with risk factors for early primary repair by right ventricular outflow tract stenting (stent). METHODS AND RESULTS: Four groups of tetralogy of Fallot with confluent central pulmonary arteries were studied: stent group (n=42), primary repair (aged <3 months) with pulmonary stenosis (early-PS group; n=44), primary repair (aged <3 months) with pulmonary atresia (early-PA group; n=49), and primary repair between 3 and 11 months of age (surg>3mo group; n=45)...

BACKGROUND: Clinical consequences of optical coherence tomographic (OCT) high-definition visualization of plaque/stent structures in acute patients remain undefined. In this retrospective substudy, we assessed the prognostic impact of postprocedural culprit lesion OCT findings in patients with acute coronary syndrome undergoing percutaneous coronary intervention. METHODS AND RESULTS: In the CLI-OPCI (Centro per la Lotta Contro L'Infarto-Optimization of Percutaneous Coronary Intervention) database collecting cases from 5 independent OCT-experienced centers, we retrospectively analyzed postprocedural OCT findings in acute coronary syndrome patients and explored its possible impact (specifically that of residual intrastent plaque/thrombus protrusion) on outcome...

BACKGROUND: The aim of this study was to assess whether deferred stenting (DS) reduces infarct size and microvascular obstruction (MVO) compared with immediate stenting (IS) in primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction. METHODS AND RESULTS: From February 2013 to August 2015, 114 patients (mean age: 69 years) were randomized into the following 2 groups: DS with an intention to stent 3 to 7 days later or IS after primary reperfusion in 2 centers...

BACKGROUND: There are currently inadequate data about whether late restenosis occurs after drug-eluting stent (DES) implantation in patients with DES restenosis. METHODS AND RESULTS: We collected data for 608 patients who received revascularization for DES restenosis between 2004 and 2012 and analyzed 688 lesions: 359 lesions treated with a first-generation DES (first DES) and 329 lesions treated with a second-generation DES (second DES). Two serial angiographic follow-ups were routinely planned for the patients (at 8 and 20 months after the procedure)...

BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main coronary artery disease. METHODS AND RESULTS: Digital databases and manual searches were performed for randomized trials comparing PCI and CABG for unprotected left main coronary artery stenosis...

BACKGROUND: The Navvus pressure sensor-equipped microcatheter allows to measure functional stenosis severity over a work-horse guidewire and is used as a more feasible alternative to regular sensor-equipped wires. However, Navvus is larger in diameter than contemporary sensor-equipped guidewires and may, thereby, influence functional measurements. The present study evaluates the hemodynamic influence of the Navvus microcatheter. METHODS AND RESULTS: In patients with intermediate coronary stenosis, coronary pressure and flow velocity were measured using a dual sensor-equipped guidewire before and after introduction of Navvus...
