A serious long-term complication of drug-eluting stent (DES) implantation is the occurrence of very late stent thrombosis beyond 1 year after implantation. We identified a series of patients who presented with acute myocardial infarction due to stent thrombosis more than 5 years after DES implantation and found that the risk persists even beyond 5 years after first-generation DES implantation. ...

A thoughtful commentary on the evolution of stent technology and resulting complications, as pertaining to this month’s article by Kaliyadan, et al....


High Femoral Artery Bifurcation Predicts Contralateral High Bifurcation: Implications for Complex Percutaneous Cardiovascular Procedures Requiring Large Caliber and/or Dual Access

Yerem Yeghiazarians, MD1;  Thomas A. Ports, MD1;  Jeffrey Zimmet, MD, PhD1

Kendrick Shunk, MD, PhD1;  Andrew J. Boyle, MBBS, PhD1,2

Recent technological advances have led to increased use of bilateral femoral artery access and the requirement for large-bore access. Our study examines the relationship between bifurcation level of one CFA and the contralateral CFA in order to better define the prevalence of high bifurcation of the CFA and the relationship between bifurcation level on both sides. ...

Clinical Outcomes in the Percutaneous Coronary Intervention of In-Stent Restenosis With Everolimus-Eluting Stents

Hyo-Soo Kim, MD3;  Moo Hyun Kim, MD4;  George Dangas, MD5;  James Hermiller, MD6;  

Mitchell Krucoff, MD7;  David Rutledge, PharmD8

Xience V USA is a prospective multicenter registry evaluating outcomes in patients treated with EES. Here, we present the 12-month clinical outcomes in patients who received EES for the treatment of in-stent restenosis (ISR) and non-ISR.     ...


The Efficacy and Safety of the “Hybrid” Approach to Coronary Chronic Total Occlusions: Insights From a Contemporary Multicenter US Registry and Comparison With Prior Studies

Advancements in equipment and the flexibility to switch between multiple technical approaches in a single procedure have dramatically increased the success of CTO-PCI. This study compares contemporary procedural outcomes of hybrid CTO-PCI with previously published CTO-PCI studies. ...

The Nature and Pattern of Coronary Stent Recalls

Sanjay Kumar, MD;  Antony L. Innasimuthu, MD;  Jonathan D. Marmur, MD

In rare cases stents have been recalled by their manufacturers due to unanticipated problems. This study examined the extent and pattern of these stent recalls. ...


Randomized Controlled Trial on the Impact of Music Therapy During Cardiac Catheterization on Reactive Hyperemia Index and Patient Satisfaction: The Functional Change in Endothelium After Cardiac Catheterization, With and Without Music Therapy (FEAT) Study

Lindsay Ripley, BS*;  Georgios Christopoulos, MD*;  Tesfaldet T. Michael, MD;  Mohammed Alomar, MD;  

Bavana V. Rangan, BDS, MPH;  Michele Roesle, RN;  Anna Kotsia, MD, PhD;  Subhash Banerjee, MD;  

Emmanouil S. Brilakis, MD, PhD

Our study objective was to determine the impact of music intervention on endothelial function, hemodynamics, and patient anxiety before, during, and after cardiac catheterization. ...


Corrected QT-Interval and Dispersion After Revascularization by Percutaneous Coronary Intervention and Coronary Artery Bypass Graft Surgery in Chronic Ischemia

Fardin Mirbolouk, MD1;  Samira Arami, MD1;  Arsalan Salari, MD1;  Bijan Shad, MD1;  

Ehsan Kazemnejad, PhD2;  Hassan Moladoust, PhD1

ECG parameters can predict cardiac events in ischemia. QT-interval parameters are potentially proposed as available non-invasive markers for assessing the ventricular homogeneity and electrical instability. Our study aim was to compare the effects of PCI and CABG on QT parameters in chronic ischemia.  ...

Standardized Methodology for Transfemoral Transcatheter Aortic Valve Replacement With the Edwards Sapien XT Valve Under Fluoroscopy Guidance

Albert M. Kasel, MD1,3;  Anupama Shivaraju, MD1,3;  Stephan Schneider, MD1;  Stephan Krapf, MD2

Frank Oertel, MD2;  Christof Burgdorf, MD3;  Ilka Ott, MD3;  Christian Sumer, MD1;  Adnan Kastrati, MD3

Wolfgang von Scheidt, MD1;  Christian Thilo, MD1

Transfemoral transcatheter aortic valve replacement (TAVR) is currently reserved for patients with severe, symptomatic aortic stenosis who are inoperable or at high surgical risk.  We provide a simplified, stepwise guide for transfemoral TAVR with the Sapien XT valve....

Comparison of Imaging Techniques to Assess Appendage Anatomy and Measurements for Left Atrial Appendage Closure Device Selection

José Ramón López-Mínguez, MD, PhD1;  Reyes González-Fernández, MD, PhD1;  

Concepción Fernández-Vegas, BSc1;   Victoria Millán-Nuñez, MD1

María Eugenia Fuentes-Cañamero, MD1;  Juan Manuel Nogales-Asensio, MD, PhD1

Javier Doncel-Vecino, MD1;  María Yuste Domínguez, MD1;  

Laura García Serrano, MD1;  Damián Sánchez Quintana, MD, PhD2  

Adequate device size selection for left atrial appendage closure is crucial to ensuring adequate implantation and for avoiding the need for multiple attempts that increase the risk of complications. We evaluate different imaging techniques to select the size of the closure device in a clinical environment....
