CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Interventions. Long-Term Safety of an Everolimus-Eluting Bioresorbable Vascular Scaffold and the Cobalt-Chromium XIENCE V Stent in a Porcine Coronary Artery Model

Fumiyuki Otsuka, MD, PhD, Erica Pacheco, MS, Laura E.L. Perkins, DVM, PhD, Jennifer P. Lane, BS, Qing Wang, MD, PhD, Marika Kamberi, PhD, Michael Frie, BS, Jin Wang, PhD, Kenichi Sakakura, MD, Kazuyuki Yahagi, MD, Elena Ladich, MD, Richard J. Rapoza, PhD, Frank D. Kolodgie, PhD and Renu Virmani, MD

Background: The Absorb everolimus-eluting bioresorbable vascular scaffold (Absorb) has shown promising clinical results; however, only limited preclinical data have been published. We sought to investigate detailed pathological responses to the Absorb versus XIENCE V (XV) in a porcine coronary model with duration of implant extending from 1 to 42 months.

STROKE. Brief Report. Modification of Outcomes With Aspirin or Apixaban in Relation to Female and Male Sex in Patients With Atrial Fibrillation. A Secondary Analysis of the AVERROES Study

Gregory Y.H. Lip, MD; John Eikelboom, MD; Salim Yusuf, MD; Olga Shestakovska, MSc; Robert G. Hart, MD; Stuart Connolly, MD; on behalf of the AVERROES Investigators

Background and Purpose: The main objective of the present analysis was to assess the effect of treatment with aspirin compared with apixaban on ischemic stroke and major bleeding in women compared with men. Female patients with atrial fibrillation are at increased stroke risk compared with male patients, and the underlying reasons for higher risk are uncertain.

CIRCULATION. Editorial. How to Stay Cool in the Intensive Care Unit? Endovascular Versus Surface Cooling

Kees H. Polderman, MD, PhD

Dozens of observational studies published over the past 2 decades have shown that fever in patients with acute neurological injury, regardless of its cause, is independently linked to higher mortality, poor neurological outcome, and increased length of stay in the intensive care unit and hospital. This has been demonstrated for traumatic brain injury, acute ischemic stroke, subarachnoid hemorrhage, intracranial hemorrhage, and cardiac arrest (CA).1,2 Therefore, therapeutic temperature management is a key goal of care in all patients with acute brain injury. In most cases the goal is strict fever control, ie, controlled normothermia; in patients with posthypoxic injuries, the goal is often to achieve below-normal core temperature, ie, to induce therapeutic hypothermia.

Background: Targeted temperature management is recommended after out-of-hospital cardiac arrest. Whether advanced internal cooling is superior to basic external cooling remains unknown. The aim of this multicenter, controlled trial was to evaluate the benefit of endovascular versus basic surface cooling.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Physiologic Assessment and Imaging. Impact of Aortic Valve Stenosis on Coronary Hemodynamics and the Instantaneous Effect of Transcatheter Aortic Valve Implantation

Esther M.A. Wiegerinck, MD, Tim P. van de Hoef, MD, PhD, M. Cristina Rolandi, PhD, ZeYie Yong, MD, PhD, Floortje van Kesteren, MD, Karel T. Koch, MD, PhD, Marije M. Vis, MD, PhD, Bas A.J.M. de Mol, MD, PhD, Jan J. Piek, MD, PhD and Jan Baan Jr, MD, PhD

Background: Aortic valve stenosis (AS) induces compensatory alterations in left ventricular hemodynamics, leading to physiological and pathological alterations in coronary hemodynamics. Relief of AS by transcatheter aortic valve implantation (TAVI) decreases ventricular afterload and is expected to improve microvascular function immediately. We evaluated the effect of AS on coronary hemodynamics and the immediate effect of TAVI.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Structural Heart Disease. Routine Screening of Coronary Artery Disease With Computed Tomographic Coronary Angiography in Place of Invasive Coronary Angiography in Patients Undergoing Transcatheter Aortic Valve Replacement

Alaide Chieffo, MD*, Gennaro Giustino, MD*, Pietro Spagnolo, MD, Vasileios F. Panoulas, MD, PhD, Matteo Montorfano, MD, Azeem Latib, MD, Filippo Figini, MD, Eustachio Agricola, MD, Chiara Gerli, MD, Annalisa Franco, MD, Manuela Giglio, MD, Micaela Cioni, MD, Ottavio Alfieri, MD, Paolo Guido Camici, MD and Antonio Colombo, MD

Background: Coronary artery disease (CAD) screening is required before transcatheter aortic valve implantation (TAVR). Although invasive coronary angiography (CA) remains the gold standard for CAD assessment, computed tomographic CA (CTCA) could be a safe and effective noninvasive alternative for CAD screening in patients undergoing TAVR.
