CIRCULATION. Quality of Care at Hospitals Identified as Outliers in Publicly Reported Mortality Statistics for Percutaneous Coronary Intervention

Stephen W. Waldo , James M. McCabe , Kevin F. Kennedy , Corwin M. Zigler , Duane S. Pinto and Robert W. Yeh

Background: Public reporting of percutaneous coronary intervention (PCI) outcomes may create disincentives for physicians to provide care for critically ill patients, particularly at institutions with worse clinical outcomes. We thus sought to evaluate the procedural management and in-hospital outcomes of patients treated for acute myocardial infarction before and after a hospital had been publicly identified as a negative outlier.

CIRCULATION. Complete Immediate Revascularization of the Patient With ST-Segment–Elevation Myocardial Infarction Is the New Standard of Care

Keith G. Oldroyd

Approximately half of patients with ST-segment–elevation myocardial infarction (STEMI) have angiographically significant multivessel disease and, in these patients, the European (2012) and US (2013) guideline recommendations have been that only the culprit artery should be treated acutely. In the setting of cardiogenic shock, the guidelines recommend treating any nonculprit arteries to achieve as complete a revascularization as possible. Both of these recommended strategies are based on level C evidence (observational studies and consensus opinion). In the past 4 years, there have been 3 new randomized trials that have contributed to the knowledge base in this area (Table).

CIRCULATION. Percutaneous Coronary Interventions for Chronic Total Occlusions: As the Technology Expands, Our Responsibilities Increase

Theodore A. Bass

The continuing evolution of new technologies has resulted in a noted improvement in procedural outcomes in patients undergoing percutaneous coronary interventions (PCI) for chronic total occlusions (CTO). We now have an expansive selection of interventional tools and techniques to successfully perform these complex interventional procedures. Coronary guide wires specifically engineered to facilitate crossing almost any CTO lesion are now available. We have developed plaque modification tools, devices facilitating directed subintimal tracking and reentry, and retrograde CTO techniques resulting in previously unimagined procedural success rates approaching >80% in the hands of experienced operators. These tools have allowed us to expand the group of patients that we now consider approachable, although CTO PCI currently represent only 3% to 4% of all PCI procedures performed in the United States. Similarly, procedural complication rates continue to decline, although other factors such as radiation exposure, contrast volume, and the increased use of costly resources remain problematic. Overall, these observations underscore the need for the cardiac interventional community to more objectively understand the risks and benefits of CTO PCI.

CIRCULATION. Brain Emboli After Left Ventricular Endocardial Ablation

Isaac R. Whitman , Rachel A. Gladstone , Nitish Badhwar , Henry H. Hsia , Byron K. Lee , S. Andrew Josephson , Karl M. Meisel , William P. DillonJr. , Christopher P. Hess , Edward P. Gerstenfeld and Gregory M. Marcus

Background: Catheter ablation for ventricular tachycardia and premature ventricular complexes (PVCs) is common. Catheter ablation of atrial fibrillation is associated with a risk of cerebral emboli attributed to cardioversions and numerous ablation lesions in the low-flow left atrium, but cerebral embolic risk in ventricular ablation has not been evaluated.

Background: Mitral valve (MV) repair is preferred over replacement in clinical guidelines and is an important determinant of the indication for surgery in degenerative mitral regurgitation. However, the level of evidence supporting current recommendations is low, and recent data cast doubts on its validity in the current era. Accordingly, the aim of the present study was to analyze very long-term outcome after MV repair and replacement for degenerative mitral regurgitation with a flail leaflet.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Efficacy and Safety of Coronary Sinus Aspiration During Coronary Angiography to Attenuate the Risk of Contrast-Induced Acute Kidney Injury in Predisposed Patients

Osama Ali Diab, Mostafa Helmy, Yasser Gomaa and Reem El-Shalakany

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.
