Google Glass is a voice-activated, hands-free, optical head-mounted display device capable of taking pictures, recording videos, and transmitting data via wi-fi. We examined the accuracy of coronary angiogram interpretation recorded using Google Glass and found that the quality may be adequate for recognition of major findings, supporting its expanding use in telemedicine. ...

Heads Up! Introducing Wearable Health Technologies in Cardiology

Muthiah Vaduganathan, MD, MPH and Deepak L. Bhatt, MD, MPH

The authors comment on this month's article by Duong et al on the use of the Google Glass in cardiovascular medicine. They eagerly look forward to the continued development of the “smart” technological platform in cardiovascular medicine; however, prior to widespread uptake of these wearable devices, more thorough evaluation of the practicality, feasibility, and clinical implications of their use will be required....

Atrial and Brain Natriuretic Peptide Secretion After Percutaneous Closure of the Left Atrial Appendage With the Watchman Device

The left atrial appendage (LAA) plays an important role in the regulation of intravascular volume via release of of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). To date, there are no data suggesting substantial effects of hormonal interaction after percutaneous LAA closure for prevention of thromboembolic events in patients with non-valvular atrial fibrillation. This study sought to evaluate the effect of transcatheter closure of the LAA with the Watchman device on the secretion of ANP and BNP. ...

Lack of Survival Benefit Found With Use of Intraaortic Balloon Pump in Extracorporeal Membrane Oxygenation: A Pooled Experience of 1517 Patients

Intraaortic balloon pumps (IABPs) are frequently used as an adjunctive device to extracorporeal membrane oxygenation (ECMO) and are routinely placed at the initiation of ECMO at many institutions. We provide a meta-analysis to demonstrate that the routine insertion of concomitant IABP with ECMO is not supported by our findings....

Impact of Switching From Prasugrel to Clopidogrel Shortly After a Percutaneous Coronary Intervention Without a Loading Dose of Clopidogrel

Eddy Mizrahi, MD1;  Ramya Smitha Suryadevara, MD1;  Kulpreet Barn, MD1;  Gouthami Boga, MD1; Mian Muhammad Ali Akram, MD1;  Ibrahim Ismail-Sayed, MD2;  Yvette M. Henry, PhD3;  Melissa A. Troup, MHSA3; Peter B. Berger, MD4

The authors present a retrospective analysis to determine the safety and efficacy of administering prasugrel at the time of percutaneous coronary intervention (PCI), and switching to clopidogrel, without reloading. 

Comparison of Iodixanol and Ioxaglate for Coronary Optical Coherence Tomography Imaging

The impact of contrast type on coronary imaging using optical coherence tomography (OCT) has received limited study. We compared OCT imaging obtained using the non-ionic, iso-osmolar iodixanol with the ionic, low-osmolar ioxaglate. 

Repeated Aortic Balloon Valvuloplasty in Elderly Patients With Aortic Stenosis Who Are Not Candidates for Definitive Treatment

A sizable group of patients with symptomatic aortic stenosis can undergo neither surgical aortic valve replacement nor transcatheter aortic valve implantation. The aim of this study was to assess the potential role of repeated balloon aortic valvuloplasty (BAV) in these patients.
