CIRCULATION. Relationship Between Arterial and Fibrous Cap Remodeling A Serial Three-Vessel Intravascular Ultrasound and Optical Coherence Tomography Study

Ryotaro Yamada, MD, Hiroyuki Okura, MD, Teruyoshi Kume, MD, Ken Saito, MD, Yoshinori Miyamoto, MD, Koichiro Imai, MD, Tetsuo Tsuchiya, MD, Tomoko Maehama, MD, Noriko Okahashi, MD, Kikuko Obase, MD, Akihiro Hayashida, MD, Yoji Neishi, MD, Takahiro Kawamoto, MD; and Kiyoshi Yoshida, MD

Background —Positive arterial remodeling and thin fibrous cap are characteristics of rupture-prone or vulnerable plaque. The natural course of the fibrous cap thickness and the relationship between serial arterial remodeling and changes in fibrous cap thickness are unknown. Therefore, the purpose of this study was to evaluate the relationship between changes in fibrous cap thickness and arterial remodeling by using optical coherence tomography (OCT) and intravascular ultrasound (IVUS) during 6-month follow-up.

CIRCULATION. Impact of Sirolimus-Eluting Stent Fracture on 4-Year Clinical Outcomes

Hisashi Umeda, MD, PhD, Tomoko Kawai, MD, Naoki Misumida, MD, Tomoyuki Ota, MD, Kazutaka Hayashi, MD, Mitsunori Iwase, MD, PhD, FACC, Hideo Izawa, MD, PhD, Shigeo Sugino, MD, Takeshi Shimizu, MD, PhD, Yasushi Takeichi, MD, PhD, Ryoji Ishiki, MD, PhD, Haruo Inagaki, MD, PhD, Yukio Ozaki, MD, PhD, FACC and Toyoaki Murohara, MD, PhD, FACC

Background—Although stent fracture (SF) after sirolimus-eluting stent (SES) implantation has been recognized as one of the predisposing factors of in-stent restenosis, it remains uncertain whether SF can increase the risk of major adverse cardiac events (MACE), especially beyond 1 year after SES implantation. The aim of this study was to assess the impact of SF relative to non-SF on 4-year clinical outcomes after treatment with SES of comparable unselected lesions. Copyright © 2011.

EHJ. Transcatheter aortic valve implantation: early results of the FRANCE (FRench Aortic National CoreValve and Edwards) registry

Hélène Eltchaninoff, Alain Prat, Martine Gilard, Alain Leguerrier, Didier Blanchard, Gérard Fournial, Bernard Iung, Patrick Donzeau-Gouge, Christophe Tribouilloy, Jean-Louis Debrux, Alain Pavie, Pascal Gueret and on behalf of the FRANCE Registry Investigators

Aims Transcatheter aortic valve implantation is a therapeutic alternative for high-surgical-risk patients with severe symptomatic aortic stenosis. Two models of prosthesis are currently commercialized in France, which can be implanted either via a transarterial or a transapical approach. The aim of the study was to evaluate in a national French registry the early safety and efficacy of transcatheter aortic valve replacement (AVR) using either the Edwards SAPIEN™ or CoreValve™ in high-surgical-risk patients with severe aortic stenosis.

EHJ. Transapical aortic valve implantation with a self-expanding anatomically oriented valve

Volkmar Falk1, Thomas Walther, Ehud Schwammenthal, Justus Strauch, Diana Aicher, Thorsten Wahlers, Joachim Schäfers, Axel Linke and Friedrich W. Mohr7

Aims The Medtronic Engager™ aortic valve bioprosthesis is a self-expanding valve with support arms facilitating anatomically correct positioning and axial fixation. Valve leaflets, made of bovine pericardium, are mounted on a Nitinol frame. Here, we report the first in man study with this new implant (Trial Identifier NCT00677638).

EHJ. Secondary stroke prevention: patent foramen ovale, aortic plaque, and carotid stenosis

Bernhard Meier1, Benedikt Frank, Andreas Wahl1 and Hans C. Diener

Stroke is a devastating event and remains as the third leading cause of mortality and the most important cause of serious, long-term disability.1 Most strokes are of ischaemic origin. Atherosclerosis plays a causative role as do other factors that vary among countries, genders, lifestyles, and a number of well-documented risk factors. In the USA, it is estimated that almost 90% of the roughly 800 000 strokes per year are ischaemic.3 Cardioembolic reasons account for 19% and carotid disease for 15% of those. A patent foramen ovale (PFO) is per se not yet considered a primary cause for stroke. It is subsumed under the ∼40% labelled cryptogenic. This paper deals with the stroke causes that are easiest to document and treat in the sense of primary and secondary prevention. Published on behalf of the European Society of Cardiology.

WJC. Management dilemmas in patients with mechanical heart valves and warfarin-induced major bleeding

Prashanth Panduranga, Mohammed Al-Mukhaini, Muhanna Al-Muslahi, Mohammed A Haque, Abdullah Shehab

Warfarin acts by inhibiting the enzymes involved in the formation of a reduced form of vitamin K, which is essential for γ-carboxylation of glutamate residues at the amino terminus of coagulation factors Ⅱ, Ⅶ, Ⅸ and Ⅹ and anticoagulant factors protein C and S. This results in production of partially carboxylated, biologically inactive clotting factors. World J Cardiol 2012 March 26; 4(3): 54-59. Copyright © 2012 Baishideng. All rights reserved

Iatrogenic free wall cardiac perforation is a rare but serious complication encountered during percutaneous cardiac procedures, which usually leads to tamponade and death. Septal occluder devices have been developed for sealing intracardiac shunts but may be also used in this emergency setting. Copyright 2011 Wiley Periodicals, Inc.
